A literature review of studies and researches has been attempted in the field of dissimilar metal welding. 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...

The material flow and microstructural evolution in the friction stir welds of a 6061-Al alloy to itself and of a 6061-Al alloy to 2024-Al alloy plates of 12.7 mm in thickness were studied under different welding conditions. The results showed that plastic deformation, flow, and mechanical mixing of the material exhibit distinct asymmetry characteristics at both sides of the same and dissimilar ...

the aim of this paper is to characterize welding of aisi 310 austenitic stainless steel to inconel 657 for use in oil-refining industries. the welds were produced using four types of filler materials; nickel-based alloys designated as inconel 82, a, 617, and 310 ss. the interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. interfaces on the two sides...

Laser welding of dissimilar aluminium alloys with filler material Luís Filipe Amaro Pinto Instituto Superior Técnico – Technical University of Lisbon – Portugal September 2008 Abstract The aluminium alloys are materials with great potential because of its high strength and low weight. However, the welding of dissimilar aluminium alloys is difficult in autogeneous welding, due to these alloys ar...

in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

In the automotive industry, a barrier to widespread implementation of friction stir welding (FSW) for aluminum joining is the perceived need for high cost, custom capital machinery. The reason for this perception is that the FSW process requires relatively large forces that commonly used automation machinery (e.g. an industrial robot) has difficulty producing. Further complicating the issue, is...
