What is the Name of the World's Largest Welding Tool?

This welding tool is part of the family of leading-edge tools developed to weld the key stage of Space Launch System - the most efficient rocket designed for deep-in-space mission.

By aluminium, many people think of aluminium foil or flimsy can of soda.

While it can’t be denied that aluminium is kinda foil, it is one of the most crucial metals when it comes to space. That’s because of its light weight and durability. To consider aluminium as the only protection against the killing void of space may not be comforting. Still, NASA’s cutting-edge aluminium alloy has, evidently, the best design for its newest generation of manned spacecraft.

In this point, NASA has designed a brand-new terrestrial welding tool shaking up aerospace manufacturing, and standing as a gigantic monument to the reasoning of measure-twice and cut-once.

Without fail, welding in space is possible in case of emergency. Still, the process isn’t really easy all the time. Laser welding gives a means of emergency repair in spite of temperature, gravity or air, but obviously, the ideal spaceship is the one that just needs welding together right in the first time.

Do Big Using Vertical Assembly Center

2014 unveiled NASA’s Vertical Assembly Center in Michoud Assembly Facility (New Orleans). It is the world’s biggest spacecraft welding equipment with 170 feet in height and 78 feet in width. Also, it’s part of leading-edge tools developed to weld key stage of SLS (Space Launch System) – the most efficient space rocket ever designed.

The Vertical Assembly Center would lift the SLS’s components up and down its striking height utilizing a big mobile ring. This ring helps swiftly and correctly position the rocket’s components when moving along rails. Then they can be welded in situ. This center applies friction stir welding – the favored welding techniques for welding aluminium in aerospace manufacturing – to connect the SLS’s components into one vehicle.

NASA's Friction Stir Welding tools (FSW) bring out qualified and strong welds in aluminum alloys employed to manufacture the Orion spacecraft, Space Launch System rocket which will travel a 4-person craw to Mars.
In March, 2015, Boeing, the manufacturer of the Vertical Assembly Center found out that its rails suffered a slight misalignment, retarding the device production in 3 months or so. This misalignment might have resulted from a shift in the soft Louisiana soil making up the center’s foundation. Still, there is no elimination to the possibility of a uncomplicated manufacturing error. Regardless of the cause, the retardation is pretty mirror, and the rocket will still be launched in 2018 as scheduled.
