New Automotive Welding Technology Expected to Create Much Stronger Bond

1. Surface tension transfer process

Surface tension transfer process (STT) developed and patented by Lincoln Electric is intended for boosting productivity by replacing such older welding methods as gas metal arc welding, gas tungsten arc welding. The benefits of this process include: reducing welding fumes and typical spatters, decreasing amount of time spent to train someone in welding technology, and increasing speed. STT welding is ideal when working with stainless steels and galvanized steel.

2. Friction stir welding


Automakers around the world are continuously looking for new ways to reduce manufacturing costs without scarifying quality and automotive safety. Companies like Honda Motor have relied on aluminum as a lower cost material, and to ensure the process of joining aluminum and steel is simple and safe, they have innovated new forms of friction stir welding. This new method helps generate more stable, secure bond between two materials by moving a rotating tool on the top of aluminum, which is then bonded to steel.

Honda engineers also have developed assembly line techniques that helps with mass production of vehicles utilizing friction stir welding – for example, a six-axis robot. According to the Assembly Manager, by replacing the conventional steel sub-frame with one comprising aluminum and steel, Honda engineers can reduce body weight by 25%. This highly efficient method also helped reduced up to 50% electricity costs during the welding process.

NASA – the hottest name in launch technology, has applied this innovative welding technique to develop the world’s largest welding tool. See more here.

3. Laser welding


Laser welding is quite new technique that involves conversing light energy into heat energy. The radiation emitted through laser welding allows beams to travel larger distances with suffering considerable loss of quality. Though initial costs for laser welding is higher than conventional spot welding methods, a significant reduction in cycle time eventually makes laser welding more efficient option.

4. Resistance spot welding


Resistant spot welding has to do with direct application of opposing forces using the pointed-tip electrodes. General Motors has availed this technique in producing lighter weight, more fuel-efficient vehicles from aluminum. By getting rid of about 2 pounds of rivets from the vehicles’ hood, doors and lift gates, engineers can utilize that weight surplus in other vehicle areas if necessary. Thanks to the resistance spot welding technology, aluminum pieces can be directly welded together using a multi-ringed dome electrode.

Keep up with changes in welding technology

In wake of rapid development of new welding technology, it’s more important than ever for your welders to be most current about changes in the technology. Being familiar with STT, resistance spot welding and friction stir welding is especially important. Vietnam Manpower Service and Trading Company ensure supplying your company with welders who are willing to learn and keep up-to-date with modern technologies.

5 Very Important Persons in Welding - Did You Know?

Welding has been around in our life and for thousands of years. Welding artifacts from the Bronze Age and Iron Age are displayed at many museums and undeniably, welders from all ages and backgrounds have contributed to welding and helped make it the way it is today. Still, there are people whose accomplishments make them most significant figures in welding.

1. Baron Auguste de Méritens

As a French electrical engineer living in 1800s, Baron August de Méritens  was the first person to find out how to use the heat generated by arc to weld the lead plates onto manufacture storage batteries. In 1881, he got the French patent for the first arc welding process. Not all, he developed welding equipment with enclosed hood and fume extraction pipe to control hazardous lead oxide fumes from hot lead. This was the beginning of the carbon arc welding technique that are commonly used today, though it was Nikolay Benardos  - Baron’s student – that went on to acquire a patent for creating the first electrode holder.

2. Nikolay Benardos

A Soviet postage stamp solely dedicated to N - the father of arc welding
Nikolay Benardos was a down-to-earth Russian inventor of 18th century. He was credited with 200 inventions in the electrical engineering realm. Benardos not just invented and marketed electric welding but produced a special electric welding battery to supply needed current for electric welding jobs. His welding inventions can be named as welding with indirect arc, welding in a gas stream, arc cutting on land and underwater as well, carbon arc welding. Carbon arc welding become especially popular in 1890s and early 1900s as it allowed individuals to weld iron and lead.

The patent for arc welding method named Elektrogefest granted to Benardos and his sponsor Stanisław Olszewski in 1887

3. Nikolay Slavyanov

Nikolay Slavyanov was another notable inventor from Russia who lived just about the same time as Nikolay Benardos. He introduced shielded arc welding 8 years or so after Benardos had invented carbon arc welding. Shielded arc welding is now one of most popular welding techniques in the world and is often used for maintenance and repair, construction of heavy steel structures and industrial fabrication. It works well in iron, aluminum, different types of steel, nickel and copper alloys.

4. Julio Gonzalez

Born in Barcelona, Spain in late 1800s, Julio Gonzalez was a remarkable sculptor and painter. Indeed, he wasn’t the first artist to create metallic sculptures using welding. What made him stand out is not only that he was a master at artistic welding but also that he strongly influenced other famous sculptors who were interested in this field. Julio Gonzalez worked extensively with Pablo Picasso – one of greatest and most influential artists of 20th century.  Gonzalez gave Picasso welder training and collaborated with him in creating many sculptures, among them is “La Tete Painte en Fer.” Julio Gonzalez is recognized as a top-notch artist from his time period. Over one hundred of his sculptures are now displayed in Museum of Modern Art (Valencia, Spain).

5. David Smith

David Smith is perhaps best known for the Cubis, which were among the last pieces he accomplished before his death. The sculptures in this series are made of stainless steel with a hand-brushed finish reminiscent of gestural strokes of Abstract Expressionist painting. The Cubi works consists of arrangements of geometric shapes, which shed light on his interest in balance and the contrast between positive and negative space.
Borned in early 1990s, David Smith was an abstract expressionist American sculptor and painter. He is famous for using various styles of welding to create sculptures. His earlier works were created using oxyacetylene torch, but later he mastered his welding art with electric arc welder. He utilized various techniques for visual effects that looked like paintings, and made his sculptures using steel, cast bronze and other metals. Also, he was an accomplished welder who worked at an auto-manufacturing factory and in locomotive construction at different points in his life.

The list is unfinished…

Welding has an ever-long and fascinating history, and unsurprisingly, famous welders have been influenced by those that had gone before them. Even so, this famous welder list isn’t finished. Let’s await other amazing people entering the list; and who knows, one or some of them may be welders from your company. These days, welders around the world are working to master the art of welding by creating new techniques, improving quality and consistency and creating new works of art.

Aluminum Welding Safety Precautions – Do You Know?

Welding does raise safety issues, especially welding aluminum. But proper aluminum welding safety precautions will ensure your welders stay safe and sound, improving productivity. 

Safety in welding has been a hot topic in this industry. Aside from general safety measures, aluminum welding safety precautions should be highlighted. You know, aluminum welding is different from other welding in many ways. Due to unique characteristics of aluminum, extra precautions need to be taken to ensure a safe and productive working environment. Ensure your welders are noticed of below things when welding this metal:

1. The appearance of heated aluminum doesn’t change

It is much more difficult to differentiate cold material from hot material when welding aluminum. More complicatedly, aluminum has about 4 times the thermal conductivity of steel. That’s why welders are recommended to label the recently completed welds as ‘hot’ and wear leather gloves to reduce the injury risk. 

2. Aluminum welding can cause electric shock. 

Just like steel welding, aluminum welding can cause electric shock, but for different reasons. In steel welding, a high-frequency arc starting option is initially applied, and then turn off in the end. In aluminum welding, this option must stay active for the weld duration; and in turn, the risk of electric shock increases. A well-insulated welding system and proper grounding can help protect welding workers in such cases.

3. Aluminum has high reflectivity. 

When welding steel, radiated light is a common concern, but it can be a serious problem in aluminum welding. Due to its high reflectivity, aluminum becomes a bigger threat when it comes to light-caused injuries. Luckily, such measures as long-sleeved clothing and light-blocking curtains can help minimize your exposure. 

4. Aluminum fumes are known as a throat irritant when inhaled, and can even cause a host of chronic symptoms. 

These symptoms include decreased nervous system performance, pulmonary fibrosis, impaired cognitive function, bronchitis, pneumoconiosis, motor dysfunction, peripheral neuropathy. To protect their breathing zone and surrounding working area, welders should: ensure cleaned welding surfaces to avoid toxic exposure; position themselves to avoid breathing welding fumes (for example, stay upwind when welding in outdoor or open environments); apply general ventilation, natural or forced movement of fresh air; use local exhaust ventilation systems; consider substituting a less toxic or lower fume-generating welding type or consumable; have respiratory protection.

As you can see, there are safety issues from aluminum welding, but the proper precautions will ensure your welders stay safe and sound, improving productivity. Check out here to have more in-depth look at safety in welding. They are helpful information, tips given by Vietnam welding manpower supplier

Just wander around the Internet, searching for welding songs to find out that there have not been one full playlist of songs about this occupation on the Internet, not even a list of some nice songs. And funnily enough, there are lots of search results about wedding songs instead of welding songs. That’s why for the post today, I will be listing as many as good songs about welding for you to complete your welding playlist. Enjoy!

1. "Welding Burns" - Rod Picott

This pure and simple song stole my heart right from the first time I heard it. Being a welder is the best thing in this world. Listening to this song, and you sure will be much prouder that you are one of hard working, tough welders. And as it's so real, it can touch someone's heart deeply to the extent that makes them cry. “Some things you’re born to. Some things you better learn. My father was born bone, muscle and blood, and welding burns”.  These lines kept lingering on my head and coming into my heart.

2. “He’s a welder” - E. Frank Murphy

Love this song. Composed by a Canadian E. Frank Murphy, it is about a real welder. The video and the song match perfectly. “He used to be a pretty nice feller...but now, he's a welder.” Great lyrics!

Powerful Tips to Boost Welding Productivity and Profitability


4 biggest welding challenges that create headaches for employers are justifying new equipment, increasing productivity, reducing cost, and finding skilled welders and/ or training new welding operators. How do you address these challenges? Below are practical tips for overcoming these pains, increasing productivity and profitability. 

These pains are shown differently depending on a company’s business emphasis, organizational structure, management outlook. They are often interrelated, and the remedy to one pain usually improves the other areas. 

Before giving you helpful tips, this post will first help better your understanding of your true cost of welding, which is an important 1st step when addressing the welding challenges. 

Understanding your true cost of welding

Many welding companies claim that people are their most important asset. In fact, most of the time, most of welding costs comes from labor (50%-85% of total expenses).  According to various different industry sources, labor almost always constitutes manual and semi-automatic welding costs (85%), while 10% of the costs come filler materials, 3% from shielding gas and 2% from power. 

But if human resources are so important, why do so many firms spend an excessive amount of effort on reducing equipment and consumables costs while neglecting the most important cost component – optimizing labor and welding efficiency?  That can only be because these companies haven’t measured, tracked, analysed and enhanced the variables that impact their welding cost and operator factor (arc time/ total labor time). Unless you measure something, you can’t manage it. To this point, here is list of items and costs that you should measure and track over time to get a baseline for managing welding operation and deciding operator factor: 

Fixed costs (hard goods):

Labor rate
Filler metal (including deposition efficiency)
Shielding gas (if used)
Other consumables (grinding wheels, gun components, backing bars, anti-spatter compound, etc.)
Raw materials (per part, if applicable)
Materials related to rejection rates (important when working with exotic or highly allowed metals)

Time-based costs and operator factor:

Preparing welding metal (degreasing, shot blasting, etc.)
Preparing the joint (cutting, beveling, grinding, if applicable)
Assembling components (place in fixtures, etc.)
Applying anti-spatter compound, if used
Pre-heating time, if required
Positioning/ repositioning weldment, if required
Tack welding components, if required
Arc-on time
Air time (moving between welds)
Interpass cooling time, if applicable
Chipping slag
Grinding spatter
Grinding/ polishing the weld bead to final size/ appearance
Getting rid of anti-spatter compound
Welder self-inspecting the weld
QA/ QC inspection and tests
Reworking/ repairing the welds and subsequent re-inspection and re-testing
Time lost because of rejected components
Changing electrodes (spool of wire, new stick rod, etc.)
Process changeover time (switch between Mig root and flux cored fill passes, etc.)
Cylinder swap-outs
Post-weld heat treating costs and time, if applicable

Fixed costs are quite easy to track (just by looking at vendor invoices), which can reason why procurement analysts often focus much on them. Time-based costs and operator factor ask for more effort to measure and track. Still, the results are worth it. 

How to spot waste

To detect waste in a system, ask yourself this key question: Is step B in a true preparation for step C or is it a compensation for inefficiency of step A?

If you spend time on such activities as chipping slag, grinding spatter, grinding welds down to the final size or re-working/ re-pairing parts, you aren’t really preparing the part for the next step in your manufacturing process. Indeed, you’re compensating for the inadequacies or undesired result of the previous step. Statistically, the labor time wasted by the compensatory activities decreases operator factor to 20% or lower in many operations. Efficient firms have an operator factor of 20-30% or higher, and they get significant financial savings as a result. 

Tips for reducing welding costs

Understand the true cost of welding and react accordingly
Lower the weld metal volume (prevent over-welding, etc.)
Minimize the rejection, reworking and scrap rates
Eliminate pre-weld preparation steps (applying anti-spatter spray, etc.) 
Eliminate post-weld grinding of spatter and excessive weld metal
Avoid paying overtime
Lower wasted effort, unnecessary motions and delays
Decrease arc time

For example, OEM Fabricators, Inc.- leading custom metal fabrication company in US., reduced its welding costs after using one type of machine, one wire and one gas for almost all of its welding. In the process, OEM managed to eliminate grinding, spatter, chipping slag, gas changeover time. The company also decreased weldment reposition and enhanced operator-to-operator consistency. 

In case you like reading:

Tips for increasing productivity

Decrease cycle time and arc-on time
Improve the operator factor (arc time/ total labor time)
Raise the deposition rates/ travel speed
Minimize rejection and reworking rates by welding it right first time
Eliminate unnecessary/ unplanned downtime
Understand root causes of bottlenecks and eliminate them
Eliminate activities that fail to add value (implement Kaizen, etc.)
Implement lean manufacturing techniques

For those who are interested in:

Tips for justifying new equipment


Understand payback and ROI calculations that are used by owners, senior managers, accountants, banks
Analyse and understand the true sources of welding costs
Get energy efficiency and utility rebates
Reduce maintenance costs/ time
Minimize unscheduled downtime

For example, by working with the local utility Puget Sound Energy, Bellingham Technical College (USA) got a $1000 per welder financial incentive that help compensate for the cost of XMT and Maxstar welding power sources. The new inverters draw 1/3 to 1/6 less amperage the college’s old welders, removed nuisance circuit breaker trips and decreased utility bills by about $200 per year per welder. 

Tips for improving operator efficiency and/ or dealing with welder shortage

Use machines that are easier for your operators to set up and understand to reduce training time
Use machines that maintain/ ensure the optimum welding parameters ( for example, machines with parameter limiting/ lockout features)
Enhance operator productivity/ efficiency to help remove the need to hire additional welders
Conduct programs and procedures to improve operator skills and enhance consistency. 

For example, Greenheck Fan Corporation - leading supplier of air movement and control equipment in U.S, had hard time finding welders, so it started its own internal training program. The company hire people that will be good employees for it, or take some of its existing good employees that are interested in becoming welders, and the company trains them to weld. It is good that they already know how to weld. Still, whatever welding experience, all welders are involved in the training program and learn what they need to know to weld at Greenheck Fan Corporation.

If you have hard time finding welders, you can rely on our welding manpower service. VMST supply Vietnamese welding workers at all levels. They are dependable, have good code of ethic and willing to learn and will be well integrated into your workplace environment.

What Kind of Welding Fumes Management Your Facility Needs?


Proper management of welding fumes is not only morally and legally imperative but also a proven way to improving productivity and quality. A safe and comfortable workplace helps better employee performance, boosts productivity and thus adds to your company’s competitive advantage. 

You may also want to have a look at:

Below is a 4-phase approach that you can use to evaluate the kind of welding fumes management your facility needs. Each phase is a possible solution to managing fumes. If you find that the phase you are considering isn’t enough to help your shop, move on to the next one.

1. Substitution

Review welding processes of your shop. It is possible to reduce fume production by changing some of the current materials. For example, you can substitute the current shielding gas with a cleaner alternative. 

2. Isolation

If substitution isn’t enough, consider capturing fumes by using vacuum extraction methods or through hoods arranged over welding zones. Fume extraction systems come in various shapes and sizes with assorted vacuum intensities and air volume displacement abilities. That means you have lots of options for fume management

3. Ventilation

If the two phases above aren’t feasible, ensuring that your workshop has good airflow is an advisable way to reduce welding fumes

4. Safe work practices

Exposure to welding fumes can be reduced by improving the safety measures, using improved housekeeping methods, using better personal protective equipment, and even ensuring proper body positioning. For instance, such respiratory protection as half masks, dust masks, supplied air solutions can reduce your workers’ exposure to fumes. Still, these respirators will be fully effective if they are well maintained, properly fit and have clean filters. They also should be tested to make sure they are compliant to OSHA safety standards. By combining the utilization of better equipment with improved housekeeping practices, you can substantially reduce fume exposure in your workshop. 

Though you’re recommended to consider these phases in order, any improvements to your shop are a positive. That’s why if using substitution and improved housekeeping practices are both feasible ways of reducing welding fumes, don’t just stop at substitution.
