Welding Metal In Space. Do metals fuse together in space. But the dexterity and precision required for TIG welding would be difficult to accomplish in zero gravity.
Since aluminum is the main metal used in space construction TIG welding would be the go-to technique for repairing parts of a spacecraft. Welding in space can be used to assemble large spacecraft and orbital stations repair spacecraft equipment and produce materials and articles with special properties that cannot be obtained on earth. In space metals can weld together without heat or meltingCheck out Audible.
Welding in space focusing on solidification heat and mass transfer and fluid flows in microgravity.
As space is always in vacuum cold welding fuses the two metal pieces. Do metals fuse together in space. Ad High Performance Wide Range Structural Adhesives Bonding Plastic and Metal. In space metals can weld together without heat or meltingCheck out Audible.
