针对高强钢低匹配对接焊接头,提出了接头静载强度与母材等强、接头疲劳强度满足某一焊趾应力集中系数要求的接头尺寸设计原则,并通过有限元计算给出了30~80 mm厚板的低匹配对接接头尺寸参数设计图。
Aiming at the low-strength butt-welded joint of high-strength steel, the design principle of joint size is proposed, in which the static strength of joint and base metal are equal and the fatigue strength of joint meets the stress concentration factor of one weld toe. mm thick plate of low matching butt joint size parameter design.
