weld heat-affected zone

基本解释

Using the heat of welding to vapour water, cooling rates are lowered on the weld bead and heat -affected zone.
利用焊接时的加热使水汽化，不仅使焊道而且使热影响区的冷却速度减慢。
The fatigue crack growth (FCG) behavior of the weld heat-affected zone of 14MnNbq bridge steel was systematically investigated in this paper.
从最弱链模型的物理本质出发，探讨了影响焊接热影响区脆性断裂的主要因素。
The basic requirement of welding the steel 2205 is that the weld metal and heat-affected zone obtain a favorable phase balance and retain the performance as the base metal after welding.
平衡铁素体和奥氏体两相组织在焊缝金属和热影响区中的比例，保证焊接接头的性能，是双相不锈钢焊接的基本要求。
