[Abstract]:Pulsed Bypass coupled arc inert gas welding is a new low heat input welding method. In view of the poor stability of coupling arc in the welding process of this method, the control scheme of controlling the stability of coupling arc by changing the wire feeding speed and adjusting the main arc length is put forward, and the simulation analysis is carried out. At the same time, the rapid prototyping technology is used to design the welding process control system and carry out welding experiments. The simulation results show that the proposed control scheme can guarantee the stability of the pulsed by-pass arc inert gas shielded welding process, and the simulation results are verified by welding experiments. At the same time, stable welding process and well-formed weld are obtained.
