welding heat affected zone

基本解释

However, as a king of quenched and tempered medium carbon steel, welding heat affected zone is the area with weak performance.
但作为一种中碳调质钢，焊接热影响区是其性能薄弱的区域。
In frequent bending stress condition, fatigue cracking occurred due to the cracking source had been initiated in welding heat affected zone.
在承受频繁的弯曲应力作用后，在其焊接热影响区萌生了裂纹源进而发生疲劳开裂。
In this paper, the process of grain growth in the welding heat affected zone(HAZ) of the super pure stainless steel of EB26—1 was simulated by a MC method.
结合焊接工艺试验和热模拟试验，运用蒙特卡罗（MC）技术模拟了超纯铁素体不锈钢EB26-1焊接热影响区（HAZ）晶粒生长过程。
