Characteristics of laterally bonded tri-metal sheets (stainless steel/Invar/stainless steel) fabricated by laser beam welding are compared to those of samples by Imphy and Hitachi Co-operations. Residual stess of tri-metal is calculated by using of the hole-drilling stain gauge method. The aging effect of stainless steel strip on welding is also discussed. In addition to, a numerical approach for laser beam welding is tried. Finally, laser beam welding system of tri-metal can be designed on th basis of experimental and theoretical results.

High Mn steel has been developed for automotive applications since the steel has an excellent combination of strength and ductility. However, from the viewpoint of welding, high Mn steel has a few problems related to its chemical composition. In this study, development of dissimilar laser welding technology has been investigated for expanding application of high Mn steel. The results have shown that dissimilar weld joint between high Mn steel and carbon steel has poor erichsen property using STS309L filler wire or not.

Welding process of ultra thin stainless steel foil was investigated using a single mode Yb-fiber laser with a CW maximum output power 40W. In micro welding, critical power density for keyhole welding was 1 to 2 orders larger higher than in macro-welding due to larger thermal conduction, extremely high speed welding becomes possible.
