Paper Abstract

A face welding technology of a titanium sheet on a steel plate for adding corrosion resistance was investigated. In the welding tests, 1800 W YAG laser beam was irradiated at different locations near a touching line of both plates through f:θ lens and was scanned within 13 mm width along the line at the frequency of 10 Hz, 20 Hz or 40 Hz. Twin rolls were set to load forces on both plates subjected to welding and simultaneously for pulling them out. The tensile shear test was carried out on each piece. Consequently, the highest strength was obtained at the frequency of 40 Hz. SEM observation and EDX analyses revealed that the formation of intermetallic compounds was smallest in this weld.
