本文叙述了常用的碳素钢、低合金钢焊接件焊后热处理的目的和选择热处理规范时的注意事项,并指出我们现行焊接件退火工艺的不足之处。此外,还对异种钢焊接热处理问题作了一番探讨,并提出改善焊接件退火工艺及管理的若干设想和建议。 This article describes the commonly used carbon steel, low alloy steel welding parts after the purpose of heat treatment and selection of heat treatment precautions, and pointed out that our current welding parts of the annealing process deficiencies. In addition, the heat treatment of dissimilar steel welding was also discussed, and some ideas and suggestions to improve the annealing process and management of the welding parts were put forward.
