Robot automation systems are rapidly taking the place of the human work force. One of the benefits is that this change provides the human work force with the time to spend on more creative tasks. The highest population of robots is in spot welding, spray painting, material handling, and arc welding. Spot welding and spray painting applications are mostly in the automotive industry. However, arc...

Abstract The resistance spot welding (RSW) method was used to join aluminum alloy AA 1050 and copper UNS C50100 sheets. Mechanical properties of the joints were examined. influence process parameters on tensile shear force discussed. design experiments (DOE) analyze mechanical joints. Three RSW used: current, squeeze time, time. results showed that joint stress increased with increasing current...

Dissimilar metal welds have numerous industrial applications in area of thermal power generation, chemical, petrochemical, automobile, aerospace industries and nuclear plants etc. The purpose of this paper is to review: (a) Dissimilar metal welds, their Metallurgical and Mechanical aspects...

Micro-friction stir spot welding (µFSSW) is one type of that suitable for joining lightweight materials. One the challenges in materials with µFSSW material easily perforated, or join not strong enough, so it necessary to select right parameters. In this article discusses about investigates micro-Friction Stir Spot Welding parameters on weld geometry, mechanical properties, and metallography di...

In order to design a future multi-material car body, both an appropriate selection of the advanced materials and suitable assignment joining methods are essential technologies, where data-base joint performance has be prepared. this research various dissimilar lap joints were fabricated tensile shear strength those was evaluated. The used ultra-high steel (UHHS), carbon fiber reinforced thermo-...

Abstract The friction stir spot welding of polymeric materials has been examined extensively; conversely, only a few researchers have addressed the dissimilar polymers. In this study, possibility polycarbonate to high-density polyethylene is examined, which not previously investigated. influence parameters, namely, tool rotational speed and dwell time, was investigated experimentally, whereas p...

High strength low alloy steel (HSLA DOCOL 500 LA) is utilized in the automotive structure because of its superior qualities such as good fatigue resistance, a high strength-to-weight ratio, assisting reducing weight vehicle, increasing fuel efficiency and lower CO2 emissions. Resistance Spot Welding (RSW) most welding technique that used to join automobile parts together. This study investigate...

Resistance spot welding is the most economical joining method for production of automotive steel bodies. In modern car body construction, however, its future applicability limited due to growing mix materials in multi-material design. response increasing weight reduction requirements protect environment and natural resources, lightweight materials, fibre-reinforced plastics (FRP) particular, ar...
