Welding, Brazing and Soldering
Commercially pure titanium and most titanium alloys can be welded by procedures and equipment used in welding austenitic stainless steel and aluminum. This article describes weldability of unalloyed titanium and all alpha titanium alloys. It reviews the selection of fusion-welding processes that are used for joining titanium and titanium alloys. The processes include gas-tungsten arc welding (GTAW), gas-metal arc welding (GMAW), plasma arc welding (PAW), electron-beam welding (EBW), laser-beam welding (LBW), friction welding (FRW), and resistance welding (RW). The article discusses the role of filler metals and shielding gases in welding titanium and titanium alloys. It describes the equipment used for gas-tungsten arc welding and concludes with information on repair welds.
