“…No additional elements are needed in this process. It is used for joining materials of 0.5 mm to about 3 mm in thickness, up to a total joint thickness of about 10 mm [1][2][3][4]. As the joints are made by local plastic deformation of the sheets, the materials should have sufficient ductility to avoid cracking [23].…”

“…Some research was focused on suitability of mechanical clinching of titanium sheets [3], even suitability of mechanical clinching of hybrid metal-polymer joints [4,5]. The optimization of a vehicle in terms of cost and performance can be achieved only by using different materials in different positions of the vehicle in order to exploit the peculiar characteristics of each different material optimized to specific use conditions [6].…”

Combination of steel sheets and aluminium alloys in components are widely used in various industrial areas because of their high performance. At times it is not possible to join this material combination utilizing conventional joining techniques, especially welding methods, therefore other alternative techniques are developed. One of the alternatives are mechanical clinching as a cold joining process. The paper evaluates the properties of clinched joints. The following materials utilized in automotive industry in car body production were used in the joining process: hot-dip galvanized steel sheet H220PD (thickness of 0.8 mm) and aluminium alloys EN AW 5754 (0.8 mm). The following tests were performed to evaluate the properties of the clinched joints: tension test -to determine the load bearing capacities and the force-elongation diagrams; microhardness test -to determine the changes in the materials joined by clinching; and a metallographic analysis observing the clinched joints' structures. Clinching proved to be suitable methods for joining the observed combination of hot-dip galvanized steel and aluminium alloy.

“…The high flexibility of clinching has allowed employing mechanical clinching for a wide range of materials. Currently, researches have been conducted on steels and aluminium alloys, recent developments have dealt with copper, mag- nesium, titanium alloys [15,16], carbon fiber-reinforced plastics [17] along with hybrid metal-plastic polymers [18][19][20], metal-reinforced plastics [21][22][23] and metal-wood [24]. Some of these materials were joined by hole-clinching process [25].…”

Joining three car body steel sheets by clinching method

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.

“…Studies on the joinability of rigid thermoplastic polymers with aluminum AA6082-T6 alloy sheets by mechanical clinching have revealed that fracture at the metal or polymer sheet was the main factor contributing to unsuccessful joinability. Joinability has been examined by studying mechanical interlocking manipulated by tool geometry [30], tool shapes [31] or temperature [32]. These studies focused on tool shapes that directly influence mechanical interlocking at the microstructural level.…”

Abstract:In this research, polyethylene terephthalate (PET), as a high-density thermoplastic sheet, and Aluminum A5052, as a metal with seven distinct surface roughnesses, were joined by friction spot welding (FSW). The effect of A5052's various surface states on the welding joining mechanism and mechanical properties were investigated. Friction spot welding was successfully applied for the dissimilar joining of PET thermoplastics and aluminum alloy A5052. During FSW, the PET near the joining interface softened, partially melted and adhered to the A5052 joining surface. The melted PET evaporated to form bubbles near the joining interface and cooled, forming hollows. The bubbles have two opposite effects: its presence at the joining interface prevent PET from contacting with A5052, while bubbles or hollows are crack origins that induce crack paths which degrade the joining strength. On the other hand, the bubbles' flow pushed the softened PET into irregularities on the roughened surface to form mechanical interlocking, which significantly improved the strength. The tensile-shear failure load for an as-received surface (0.31 µm R a ) specimen was about 0.4-0.8 kN while that for the treated surface (>0.31 µm R a ) specimen was about 4.8-5.2 kN.
