Welding technology is an important connection technology in the aerospace field. It plays an increasingly important role in promoting the development of aerospace manufacturing technology, achieving weight reduction and high efficiency of aircraft; to a large extent, it improves the quality of welding and improves The efficiency of the production of aircraft parts effectively reduces costs and fully realizes efficient production. We believe that with the continuous advancement of welding technology, the level of my country's aerospace industry will also be significantly improved.

1 Laser welding is mainly applied to the splicing of large aircraft skins and the assembly of fuselage accessories.

2 Friction stir welding technology has been widely used in the assembly of aircraft skins and wings, as well as aircraft floors and other structural parts.

3 Linear friction welding is mainly used in the manufacture of integral titanium alloy blisks of engines.

4 Diffusion welding technology has been applied to the titanium alloy rotors of helicopters, the beams of aircrafts, the engine casing and the overall turbines.
