The effects of welding force and welding electric current on the tensile strength of mash seam welded joints in the interstitial-free (IF) steel have been studied.
研究了焊轮压力和焊接电流对无间隙原子钢(if钢)压平缝焊接头抗拉强度的影响。

Also, improve the overlapped length of the tail frame and the frame and change the welding seam into intermittent seam, therefore the frame strength can be effectively increased.
改善尾架与车架的搭接长度,将连接焊缝改为断续焊缝,从而有效地提高了车架的强度。
