    摘要： A method for weldbonding together metal sheets includes applying adhesive on the surface of a first sheet and placing a second sheet atop the first sheet. The sheets are heated at a selected location to a high temperature forming a metallic weld nugget between the first sheet and the second sheet. The adhesive may be a heat curable adhesive that is cured by the heat, or the adhesive may be heated at ambient temperatures. One or both of the sheets is then cooled in the area surrounding the selected location of heating so that the high temperature needed to created the metallic weld nugget is prevented from transferring so far beyond the selected location as to overheat the adhesive layer and thereby degrade the quality of the adhesive bond.

    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.
