We succeeded in mass production of epoch-making single-layer metal gasket by laser welding. The effects of manufacturing conditions on the joint strength are investigated experimentally. Based on the experimental results, (1)Joint strength increases linearly with the increase of welding bead width. (2)If there is a gap between shim and substrate which are welded together, joint strength becomes small. Therefore, clamping at welding is an Important manufacturing conditions. (3)The range of focusing the position of laser beam to get the-optimum joint strength is quite narrow.
