Abstract Spot welding is widely used in car industry to create a cheap and light body and chassis. Engineers tend to use spot-welding in order of reducing the production costs, also lowering the stress intensity which can cause failure and fractures of the body or chassis. Our goal here is to examine spot-welding of a car body with different tests and find out later if there is a possibility of using a different technology that can produce a better seam that can be automated with industrial robots.

Abstract The optimization of a car body in terms of cost can be achieved by using different materials in various positions of the car in order to utilize specific properties of each different material. Resistance spot welding is the most used method of joining in car body production, but it is not always easy or even possible to join some combination of materials by this method. Clinching is an alternative method to spot welding, as a combination of drawing and forming. The research is focused on the evaluation of clinched joints’ properties using shearing test and metallographic observation of material structure.

Resistance spot welding is the dominant method for joining the materials in the car body production. Progressive materials are being developed to improve the car’s fuel consumption and the safety of passengers as well. Advanced high strength dual-phase steels are such materials. Despite of the dominancy of resistance spot welding in car body production, innovative methods are being developed to reduce the joining time, process costs and improve the load-bearing capacity of a particular joint. Mechanical clinching is such process. The research focused on the evaluation of the possibility of clinching as an alternative method to the resistance spot welding. Experimental samples were prepared from dual-phase steel sheets DP600. The samples were tested by uniaxial tensile test, microhardness test and metallographic observations. Both joining methods have advantages and disadvantages which could destine them for specific utilization. Clinching joining is a progressive, fast and low-cost technique, but the joint’s load-bearing capacity is lower when compared to resistance spot weld.

Various ferrous and non-ferrous materials and their combinations are used in car body production in automotive industry. The most commonly used method for joining the materials is resistance spot welding. Some materials or combinations of materials are very difficult or impossible to join by resistance spot welding. Therefore, car producers are seeking for alternative joining methods. One of the innovative joining alternatives is clinching. The paper presents the results of evaluation of clinched joint properties. The high-strength dual-phase steel sheet DP600 in combination with the drawing grade steel sheets DC06, DX53D+Z and DX51D+Z were used for experiments. The influence of position of the sheets relative to the punch and die of the tool on the carrying capacities of the clinched joints was observed as well. The tension test and metallographical analysis were used for the evaluation of clinched joint properties.
