Joining Car Body Steel Sheets Using the Clinching Method

Emil Spišák, Ľuboš Kaščák

The paper deals with joining steel sheets for automotive industry using the clinching method. This method is a relatively new technique in joining car body sheets and it is beginning to find its place in the automotive industry as an alternative to resistance spot welding, especially in joining materials of different qualities or materials with different surface treatment. Combination of three hot-dip galvanized steel sheets: microalloyed steel sheet H220PD with the thickness of 0,8 mm, TRIP steel 40/70+Z100MBO with the thickness of 0,77 mm and drawing grade sheet DX51D+Z with the thickness of 0,9 mm were used for the experiments. The tensile test and metalographical analysis were used for the evaluation of the clinched joints properties. We observed the influence of the sheets' position during clinching (taking into consideration the materials and the active parts of the tool - punch and die) on the carrying capacity of the joint.
