The invention discloses a
titanium and
titanium alloy component
arc welding adding material
remanufacturing method. In the
arc welding adding material
remanufacturing process, the pulse MIG
welding technology is adopted, the mode of
metal transfer is spray transfer, a double-microdomain adjusting mode is adopted in
gas protection, the appearance structure is a
bell jar type or a ship type, and a front stretching and back extending mode is adopted in protection gas supplying and non-supplying; the inclination angle theta and the inclination angle
omega of opposite
welding lines of a
welding gun are controlled;
argon or
argon-
helium or
helium-
argon or
helium is adopted as the double-microdomain protection gas; an
arc welding robot is adopted to control the
moving speed and posture of the welding gun. The
titanium and
titanium alloy component arc welding adding material
remanufacturing method solves the problems of
gas protection, technology optimization and
quality control in the titanium and
titanium alloy component MIG arc welding adding material remanufacturing, adding material remanufacturing of abraded or broken titanium and
titanium alloy components is achieved, the
gas protection structure is simple, easy to use and good in protection effect, a sealing
gas chamber is not needed, more than 40 percent of materials can be saved, the thermal input can be reduced by more than 20 percent, and the titanium and titanium
alloy component arc welding adding material remanufacturing quality is improved.
