Purpose: of this paper is to present the recent possibility of evolutionary optimization method application to predicting the proper welding parameters in the weld process. The objective of the welding simulation is to study the temperature generated during the welding process and to investigate residual stresses in the component after the welding. Such results give the possibility to determine...

Dissimilar Welding of Austenitic and Martensitic Stainless Steel Joints are commonly preferred in Nuclear Reactors where high temperature applications needed. There has been a huge demand for materials which sustain corrosive environment with rupture strength along pressure. These can be directly replaced the traditional nickel based alloys to compensate cost cutting satisfy requirements. weldi...

Inert-gas Arc Welding of Aluminium Aluminium is used widely in metal fabrication processes, chiefly on account of its lightness, the ease with which it may be cast, and its extreme ductility. It is also highly resistant to corrosion, owing to the formation of a protective film of oxide on the surface of the metal. This latter property, however, becomes a disadvantage when it is desired to weld ...

The pulsed laser welding of Al ribbon to Cu sheet was investigated for the electrical interconnections in power electronic modules. various experimental conditions with different powers, scan speeds, and heat inputs were employed obtaining defect-free Al/Cu joints. During welding, intermetallic compounds formed zone. An electron probe microanalyzer transmission microscopy confirmed phases compo...

Martensitic stainless steel AISI 431 and low carbon 1020 are materials used together in many different industries. However, important problems encountered when welding (fusion welding) these to each other. For this reason, friction process (Solid-state is join dissimilar metals. There very few studies on joining with welding. Therefore, the optimization of parameters pairs great important. In a...

Friction stir welding (FSW) is a recently developed solid-state joining process that uses a specially shaped rotating tool to produce lap or butt joints. At the National Research Council, an inter-institute collaboration was started in 2007 with the goal of exploiting the NDE expertise and applying it for the characterization of friction stir welds for various industrial applications. In partic...

Health monitoring of structural joints is a major concern of the engineering community. Among joining techniques, spotwelding play a major role. Spot welding is the traditional method of assembly for steel-based automotive structures, while spot-welding of aluminum is being considered for future vehicular structures. Though spot welding of steel is well researched and understood, the spot-weldi...

Hollow sections are most suitable for welded connections between members. The welding procedure is fairly straightforward in RHS, because they do not require profiling which is necessary for circular hollow sections. Although many multiplanar and uniplanar joints in structures are present, limited evidence is available for the fatigue behaviour of joints made of rectangular hollow sections. Thi...

Friction Stir Welding (FSW) is considered to be the most significant development in metal joining technologies to join high strength aerospace aluminum alloys. In order to improve the reliability and quality of the products manufactured by FSW process input process parameters such as tool rotational speed, welding speed and axial force are to be optimized. This study deals with the optimization...
