Weldability of titanium and titanium alloys
, 1965 The literature on the welding of titanium and its alloys is reviewed. Titanium is very reactive and is easily contaminated by carbon, hydrogen, oxygen or nitrogen. During welding, the hot metal must be protected at all times from the atmosphere, and it may be necessary to pay special attention to the purity of inert gases used for shielding ...
