摘要： Method of welding a carbon steel and a austenitic stainless steel involves using high density energy beam like a laser beam or electron beam. Welding using high density energy beam is effective to obtain a high precision welding. For the purpose of obtaining both high precision and no cracks, and no deformation, the method of the invention controls the structure of a weld portion to be a mixed structure of an austenitic structure and not greater than 20 wt % of a ferritic structure.

摘要： A method whereby defect-free welds can be produced in joining metallic members of dissimilar materials by electron-beam welding. The method consists in inserting one of the metallic members in openings formed in a metallic plate of the same material as the other metallic member and welding one metallic member to the metallic plate by providing a weld metal, providing by overlay welding on the weld metal a padding metal of a material substantially similar to that of the other metallic member but lower in oxygen content, effecting machining of the outer surface of the padding metal to form a faying surface, and joining by electron beam welding the faying surface of the padding metal to a faying surface formed on the other metallic member whereby the faying surfaces can be rigidly welded.
