摘要
研究了以低合金钢 WDL 61 0 D为试验材料所得埋弧焊缝 ,经 SR处理 (即消除应力处理 )后对其机械性能 (包括强度、硬度、韧性 )和组织的影响 。
This paper has mainly studied the effect on properties and microstructure of WDL610D that has been welded by submerged are welding post weld stress relief treatment. It provides a dada base of the effect of WSRT on properties when annealing system is selected in work.
