In this investigation, were studied that how the heat treatments after welding affect the weld properties of titanium alloys (5% Al-2.5% Sn-Ti, 2% Al-2% Mn-Ti and 5% Al-3% Mn-Ti alloys) which thought to be practical. These titanium alloys, except 5% Al-3% Mn-Ti alloy, have considerably good weld properties in as welded, and to do the properties excellently, the following heat treatments are available after welding. 1) For 5% Al-2.5% Sn-Ti alloy, give water cooling after heated in 800 to 900℃ 2) For 2% Al-2% Mn-Ti, 5% Al-3% Mn-Ti, and 8% Mn-Ti alloys, give water cooling after heated in 650 to 700℃ And the properties of welds of such heattreated, in high temperature, are as good as the base metal.
