METHOD FOR MANUFACTURING A WELDED ASSEMBLY

摘要

A method for manufacturing a welded assembly from first and second components which are comprised of similar or dissimilar metals. The first and second components are aligned so that they are in contact with one another along an abutment line and are welded together to form an as-welded assembly in which the first and second components are joined together by a weld joint extending along the abutment line. After formation of the weld joint, the as-welded assembly is heat treated by first heating it to a pre-determined temperature and then cooling it. The method provides a welded assembly in which the properties of the heat-affected areas in the region of the weld joint are normalized with remaining portions of the assembly.
