Abstract

A feasibility study was performed to see the welding possibility of dissimilar thin-plat materials. These materials were welded for finding the optimum welding condition and evaluating the soundness of welding zone. The welding was attempted under the condition of laser power 500~600w, Pulse width 1.0~2.5ms and frequency 11~18Hz. In this study, the highest tensile-shear strength was observed at laser the low frequency. The suitable welding condition can be obtain at the large pulse width and the low frequency.
