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： A method of controlling an indentation depth of an electrode into a metal substrate during formation of a weld includes selecting a weld force, current, duration, minimum indentation depth, and maximum indentation depth, contacting the substrate with the electrode to apply the force to the substrate, supplying the current to the electrode to initiate formation of the weld according to a first condition in which the depth is less than the minimum, a second condition in which the depth is greater than or equal to the minimum and less than or equal to the maximum, and a third condition in which the depth is greater than the maximum, and comparing the depth, minimum, and maximum. For the first condition, duration is changed. For the second condition, each of the force, current, and duration is maintained until the weld is substantially formed. For the third condition, current ceases to be supplied.

摘要： Method and apparatus for detecting unacceptable misalignment of welding electrodes. An electrode-alignment station is positioned adjacent a welding station. A robot controls the movement of the electrodes, and occasionally moves the electrodes out of the welding station and into an electrode-alignment station. At the electrode-alignment station, the electrodes are closed on a fixture that transfers electrode-misalignment into movement of a plate that triggers an alarm if the misalignment is greater than a prescribed amount.

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.
