Performance characteristics of welded tantalum crucible
Welded tantalum crucible
Strength: Due to the presence of welds, its overall strength may be slightly lower than that of seamless tantalum crucibles. The weld may be a weak link. When subjected to greater external force or high temperature and high pressure environment, the weld may crack and other problems.
Sealing: Although post-processed, there may still be tiny pores or defects in the weld, resulting in poorer sealing than seamless tantalum crucibles. In some applications with extremely high sealing requirements, additional sealing measures may be required.
Corrosion resistance: The chemical composition and organizational structure of the weld may be different from those of the parent material. In some corrosive environments, the weld may be more susceptible to corrosion. However, for general corrosive media, welded tantalum crucibles still have good corrosion resistance.
