Interfacial reaction control during pulsed argon arc welding of SiCp/Al composites

The interfacial reaction control of SiCp/2124Al composites was investigated during pulsed argon arc welding. Meanwhile, the mechanical properties, the metallographic structure and interfacial microstructure of the induced welding joint were tested and detected. respectively. The results reveal that the joint with excellent properties could be achieved by the proper selection of the special filling material and the addition of the pulse during welding. Moreover, the formation mechanism of the welding joint was discussed and the corresponding measures on further improving the quality of the welding joint of SiCp/2124Al composites were put forward in the condition of pulsed argon are welding.
