通过描述车体组成大部件侧墙的焊接结构,分析单双丝MIG焊接的优缺点,并根据理论计算,最终确定工装上蘑菇头的反变形量,有效控制了侧墙的焊接变形。
The advantages and disadvantages of single and double wire MIG welding are analyzed by describing the welding structure of the large body side wall of the car body. Based on the theoretical calculation, the inverse deformation of the mushroom head is finally determined, which effectively controls the welding deformation of the side wall.
