Robotic automatic welding of the car seat bracket is difficuh because of its complex structure and solder joints. By analyzing the welding process of the automobile seat bracket,the main welding parameters and the feasible instruction scheme of robotic automatic wehting are given. And a welding work manual is made to streamline the robotic welding process.Robotic automatic welding can solve the problems caused by high welding rate and complicated solder joints. It gives solutions on the welding process incidents. And it reduces the high labor cost and intensity and improves the labor environment. Robotic automatic welding makes no pores, cracks, wear, undercut and slag inclusion, and makes smaller splash. The stability and the consistency of welding robot can overcome the shortage of human factors, and make the products beautiful, stable and reliable, so welding robot has strong engineering practicability.
