Efficient welding of dissimilar materials imposed a major obstruction due to the non-uniformity in thermal mechanical and chemical properties of the materials to be welded under common welding conditions. Microstructures of the welded materials may be affected by welding parameters like change in materials, weld current, weld angle, weld position, hold time and other parameters which cause a sudden change of the thermal, mechanical and chemical properties along the weld. Different defects come up in dissimilar materials welding like surface defects, residual stresses during welding causing stress concentrated on one side of the weld, tensile and compressive thermal stresses, corrosion cracking, etc. The current research includes experimental investigation for the welding of dissimilar materials with different parameters (i.e. materials, weld current, hold time and weld position) to improve microstructure and thermal, mechanical and chemical properties of welded joints. Non destructive testing and Scanning Electron Microscopy (SEM) will be carried out for the analysis of the welded materials and their microstructures.
