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...

Electron beam welding has shown a remarkable job in the space industry for welding of components. It is performed under a vacuum environment that eliminates foreign matter such as hydrogen, oxygen, and other gases. Joining of similar and dissimilar materials is the main advantage of electron beam welding with high depth to width ratio as well as sharp focus at the point where parts are to be we...

Microstructural changes during laser welding and laser surface treatment has been regarded by many researchers. Most researches have focused on studying the effect of various process parameters on the size and microstructure of the heat affected zone. But some studies show that the initial microstructure of the base metal can also affect the heat affected zone dimensions and final microstructur...
