Joining the car-body sheets using clinching process with various thickness and mechanical property arrangements

The clinching joints are more and more used when assembling sheet plate elements, especially in an automotive industry. The clinching joint is created by local stamping of joined sheets without heat effect on the material structure. This paper presents the analysis of effect of the thickness layout change and sheet type and die on the joint strength change. The shearing strength analysis of created joints has been presented. The shearing test results of the clinching joint have been compared with results achieved for spot welding joints of similar joint diameter.
