In addition, to weaken the effect of double quenching on the microstructure and properties of ASTM4130 steel, multi-pass welding and temper bead should be adopted.
另外为消除二次淬火对ASTM 4130钢组织和性能的影响，应采用多层多道焊，并添加回火焊道。
If a temper bead technique is used to control the maximum hardness of the HAZ then any change in the bead sequence or placement of the temper bead shall require a new qualification.
如果这个回火焊逢工艺被用作控制热影响区的最大硬度，那么，在回火焊缝工艺中焊缝的排列顺序的任何改变，都将符合新的标准。
