Welding of niobium TIG
Use a non-consumable tungsten electrode. The weld zone is protected with inert gas both on the front and back sides of the welding zone.
Electron beam welding
This type of welding in a high vacuum can be welded niobium sheets with a thickness of 1 mm.
Comparative efficiency
The content of carbon and oxygen in the weld metal did not change during TIG welding, but was significantly reduced in electron beam welding. The content of nitrogen in the weld metal and the hardness of the welded seam in electron-beam niobium welding were greater than when welding TIG in an atmosphere of 99.99% argon. During the test of the strength of the welded seam by electron beam welding, the gap occurs only over the weld zone, while the gap in welded joints obtained by the TIG method occurs in the region of the thermal impact zone, or even over the base metal.
Storage
In closed warehouses or under a canopy, where adequate protection against mechanical and other damages is provided.
