The fatigue resistance of the butt welds can be improved by means of removing the weldreinforcement and designing the weld in the maximum shear stress plane.
去除焊缝余高或将焊缝设计在最大剪应力平面内可明显改善对焊接头的疲劳性能。
2
While the butt weld lap and the weldreinforcement exist simultaneously, the detecting methods of reinforcements are described.
叙述了对按焊缝错边与焊缝余高同时存在时的焊缝余高检测法。
3
Produced stress concentration if weldreinforcement too large for submerged arc welding, so it should be control.
