A reliable way to improve the quality of spiral pipe was the substitution of high frequency butt welding for HF lap welding.
高频对焊代替高频搭焊是提高中直径螺旋焊管质量的可靠途径。
According to the different product structure, butt fusion welding process and lap seam welding process are used to respectively weld left and right half shell of upper body.
上体左、右半壳直焊缝视产品结构不同，分别采用对接熔化焊和搭接缝焊工艺。
The results shown that a deformation-free joint with good weld surface appearance can be obtained with suitable welding conditions for butt-joint and lap-joint of the dissimilar materials.
结果表明，当焊接工艺参数合适时，可以获得表面成形良好、无变形的铝合金与钢的对接接头和搭接接头。
