The MIG Welding of Thin-Walled Tantalum Elements

Research-related tests discussed in the article included the manual TIG welding of thin-walled elements made of tantalum, i.e. a sheet having a thickness of 0.55 mm, a tube (Ø10×1.0 mm) and a chemical equipment nozzle tip. Welding jigs were placed in a chamber filled with argon. The verification of the correctness of the welding technology developed during the tests included the welding-based filling of the crack in the girth fillet weld of the tantalum tube and the making of a repair weld in the nozzle tip.
