Tailor-welded blanks tensile tests in which the weld lines parallel to the axis of tension are performed and the weld metal properties are determined using a "rule of mixtures" type of calculation. 采用两种焊缝建模方法对拼焊管的轴向变形进行了数值模拟和实验研究,分析了不同建模方法和料厚比对拼焊管轴向变形的影响。
Height track system of weld gun adopts height displacements sensor to time inspect the height of work part, and inspected signal after A/ D transferred and signal PC bias calculation is used to drive axis motor to adjust height of weld gun. 焊枪高度跟踪采用高度位移传感器,实时检测工件高度,检测信号经A/D转换、单片机偏差计算,驱动焊枪高度轴电机进行焊枪高度的实时纠偏。
Because the side beam is asymmetric, and the external four longitudinal weld locate four corner of longitudinal neutral axis ( X axis) of the side beam. For the groove weldment, the shrinkage of weld metal is the main factor making residual welding deformation. 由于侧梁非严格对称,且外部4条主焊缝环绕在纵向中性轴(X轴)的四个角点;焊缝金属收缩是形成焊接残余变形的主要因素。
