Why a giant tent? Why not normal MIG/TIG welding that floods just the weld area with argon?

- msandford 11y agoBecause I misspoke and it's actually that any hot titanium will form brittle oxides. The Heat Affected Zone (HAZ) extends far further than the weld puddle, so you need to substantially increase the coverage of your flood, usually far enough that it makes sense to do the welding inside of a bag, down in a tank, etc. I heard that one of the titanium bicycle manufacturers actually had whole rooms that they flooded and the welders just wore masks that gave them air. Totally a "I heard it from a friend who heard it from a guy" kinda situation though. http://www.twi-global.com/technical-knowledge/job-knowledge/welding-of-titanium-and-its-alloys-part-1-109/ http://www.twi-global.com/technical-knowledge/job-knowledge/...
