抄録

This paper describes the wledability for diffusion welding of stainless steel to mild steel. For this purpose, the joint tensile strength and microstructures were investigated. And the effect of insert materials was also examined.<BR>The results obtained are as follows.<BR>(1) The joint strength depends on the welding temperature and the surface roughness remarkably. The relation between the strength and the surface roughness for the dissimilar joint of stainless steel to mild steel has the same tendency as that of the similar joint between the mild steels.<BR>(2) When the joint is welded at about 800°C, chromium carbide is formed at the stainless steel near the joint interface due to carbon migration. If the welding temperature is higher than the sensitizing temperature range, chromium carbide precipitated zone along the joint interface is not formed.<BR>(3) To avoid the formation of chromium carbide precipitated zone and decarburized zone due to carbon migration, the insert material, nickel is effective.<BR>(4) To increase the weldability of the joint, which surface has been roughly treated, the insert material, silver is useful, when the welding temperature is high.
