The rear axle is one of the key components for automobiles as the transmission of power and the backstop of car load. The rear axle was welded using GMAW with PLC. The welding process was researched through the analysis of welding material and welded construction. The mechanical property and microstructure of welded joint were studied to define optimal welding procedure parameters. The results show that the properties of welded joint are improved by means of PLC. The properties of rear axle meet the need of responding criterion.
