Abstract
A comparison test of conventional MIG welding and ultrasonic-MIG hybrid welding was carried out in this paper. The effects of transverse ultrasonic vibration on weld formation, weld microhardness and weld microstructures during ultrasonic-MIG hybrid welding of 1 mm thick galvanized steel sheet were discussed. Microstructures of weld were analyzed with optical microscopy and scanning electron microscopy, and microhardness of weld joint was measured with Vickers hardness tester. The results show that the grains in welded zone of ultrasonic-MIG hybrid welding are finer and uniformly distributed; the hardness of the whole weld zone is more uniform; weld width increases; and weld depth and residual height decrease compared with the conventional MIG welding.
