Inverter GMAW process characteristics based on new cotrol method

With the application and development of GMAW,the common used welding machine usually cant adapt to new environment and requirement ,for example pipeline welding in western gas to east part,container high-speed welding,short welding line welding in automobile industry,size control in angle welding line and melding pool deep control in narrow space,in addition,super sheet welding,double PMIG/PMAG welding,twin arc welding,TIME high efficiency welding and magnetic controlled MAG welding,these welding processes with special function are called characteristic welding,which have their own characteristics and can satisfy some special welding,it will be new increasing point of GMAW application.
