no welding zone 不结合区
zone of welding current 焊接电流调节范围
welding heat affected zone 焊接热影响区
welding pool reacting zone 熔池反应区
welding heat affecting zone 焊接热影响区
The changes of microstructure in welding zone and its vicinity were observed, and flexural strength of the welding zone was also tested.
观察分析了焊接区及其附近的组织变化，测试了焊接区的室温弯曲强度。
The stress of the welding zone decreases with the increase of the distance between the welding zone and other stress concentration zone.
焊缝位置越远离其他应力集中区，焊缝应力越小；
By using this process to repair castings, there is no obvious separating line, no slag inclusion and gas hole between the welding zone and base metal.
用此工艺焊补铸件，焊补区域与基体间没有明显的熔合线，无渣孔、气孔等缺陷。
