Abstract

In this research, CMT-Plus was applied to spot weld aluminum 5052 using Al-5Si filler metal with the different feed speed of 2, 4, 6, 8 and 10 m/min. To study the weld base high, microstructure, and strength of the welded joint. The investigation results showed that the different wire feed rate of filler metal significantly affected the all results of the welded joint. The weld base high, microstructure, and peeling resistance was excellent when using the feed speed at 4 m/min. The filler metal was very well spread, complete fusion and the spot weld exhibited a little of weld base high. The microstructure exhibited a low defect of micro crack and porosity. Fusion zone occurred only the Al9Si intermetallic phase in the Al matrix with a face-centered cubic structure. The intermetallic phase in spot weld was small and uniform distribution. The peeling resistance was excellent when using the optimal feed speed. The larger areas of fracture failure and the maximum peel strength was 0.39 kN.
