摘要： A method to diagnose weld integrity in a welding process includes monitoring a weld indentation characteristic, comparing the monitored weld indentation characteristic to a threshold weld indentation characteristic, and identifying a discrepant weld when the weld indentation characteristic comparison shows the monitored weld indentation characteristic violates the threshold weld indentation characteristic.

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.
