A Study on the Bead Stability in High Speed TIG Welding

고속 TIG 용접의 비드 안정성에 관한 연구

  • Published : 1994.08.01


TIG welding process is applied for the active metal such as aluminum and titanium, also sometimes for overlay welding of superalloy. However the welding speed to be applied is very low because of the unstable bead formed in the region of high current and high welding speed. The present study was carried out to examine the basic phenomena of high speed TIG melt run welding by the 2% Th - W electrode(dia.3.2mm) of various tip shapes.
