Abstract

Titanium alloy is known as the “third metal” after steel and aluminum. Due to the characteristics of low density, high specific strength, high stiffness and good corrosion resistance, it is widely used in aerospace, rail transit and weapon military industry. With the rapid development of equipment manufacturing industry, the demand for titanium alloy materials is increasing, so more stringent requirements are put forward for welding manufacturing process of titanium alloy structures. The development status of titanium alloy welding technology was reviewed, including laser filler wire welding, laser-arc hybrid welding, metal inert gas welding, argon arc welding and so on. The development trend of new welding technology of titanium alloy was prospected. It was found that traditional welding processes such as metal inert gas welding and new welding processes such as laser welding could be used in titanium alloy welding. Traditional welding technology had lower use and maintenance costs, higher welding efficiency but poor weld formation, which made it more suitable for manufacturing large titanium alloy parts. The welded joints of the new welding process were more well-formed, but the welding efficiency was low and the equipment use and maintenance costs were higher, which made it more suitable for the production of precision titanium alloy parts.
