摘要： A joining operation for a stack of three metal sheets performed using only a single welding step, with access to only one sheet side being required. An inner sheet of the stack has formed therein a pair of bifurcated projections, wherein at least one first apex faces in one direction and at least one second apex faces in the opposite direction. First and second outer metal sheets are assembled with the inner sheet, wherein the first outer sheet abuts the at least one first apex, and the second outer sheet abuts the at least one second apex. A projection welding apparatus welds the sheets, using only access to the first outer sheet superposed the bifurcated projections, wherein a majority of the current flows through the second outer sheet.

摘要： A method of monitoring and maintaining a weld cap which is executing successive resistance welds on a plurality of workpieces includes measuring a first weld indentation formed during a first resistance weld and measuring a second weld indentation formed during a second resistance weld. The measured first and second weld indentations are compared with a severe threshold. If either of the measured first or second weld indentations is greater than the severe threshold, an abnormal condition is signaled. The method may include tip dressing the weld cap based upon the signaled abnormal condition. The method may further include determining a degradation rate between the first resistance weld and the second resistance weld. The degradation rate is the time differential between the measured first and second weld indentations, and either a first or a second tip dressing schedule is chosen based upon the determined degradation rate.
摘要翻译：一种监测和维护在多个工件上执行连续电阻焊接的焊接帽的方法包括测量在第一电阻焊接期间形成的第一焊接压痕和测量在第二电阻焊接期间形成的第二焊接压痕。将测量的第一和第二焊缝凹陷与严重阈值进行比较。如果所测量的第一或第二焊缝中的任一个大于严重阈值，则发出异常情况。该方法可以包括基于发出信号的异常情况来对焊接盖进行末端修整。该方法还可以包括确定第一电阻焊和第二电阻焊之间的退化率。降解率是测量的第一和第二焊缝之间的时间差，并且基于所确定的降解速率来选择第一或第二末端修整程序。
