| Popis: | This paper presents a research of the lap joint shear strength of S350GD+Z sheet material joined by resistance spot welding. The resistance spot welding process was done for five values of welding current. The joints strength structure analysis was done for the shearing curves. The influence of the welding current on the joints maximum strength and the shear curve of the resistance spot welded joints was presented. Welding current increase influence efficiency on the joints strength was analyzed. The analysis of the cold plastic formed joining technologies (clinching) was also presented. The clinching joints were made by using different tool types and uniform values of embossment minimum thickness. The influence of tool shape on the joint strength was described. In the case of round clinching joints the influence of forming force increase on the joints strength was studied. |
