Title:
応力に敏感な材料上に溶接するための方法
Document Type and Number:
Japanese Patent JP4729248
Kind Code:
B2
Abstract:
For stress-crack-sensitive materials, a weld pool is formed on a substrate. The weld pool is simultaneously plastically strained and cooled while the temperature of the hot metal weld pool lies substantially within a predetermined range in which hot cracking typically occurs. The hot metal is plastically strained and cooled until the temperature of the weld material is below the predetermined temperature range associated with hot cracking or until residual stresses in the weld are sufficiently low to preclude cracking in the completed weld.
