Design and implementation of welding workstation of second frame beam assembly

Automatic welding of light truck frame second beam is difficult because the beam has too many full welding structures and welding points,and the welding parts vary in thickness.Through the analysis of assembly welding process of second beam frame,the design scheme and the instruction of second frame beam assembly welding workstation is given.Automatic welding robot has solved problems of complex welding position,adapted to high welding rate,reduced labor intensity and improved working environment.It makes the welding process totally automatic and improves the welding efficiency.Effective countermeasures are put forward in the debugging process of welding to solve the problems of bum-through,welding undercut,small welding nuclear defects.The consistency of automatic welding workstation has overcome welding problems caused by human factors,which guarantees the stable quality and the beautiful appearance,and has very high engineering application value.
