Abstract: The quality of welded joint is depends on metallurgy of weld bead, Weld metallurgy depends upon the rate of heat and metal transfer to the joint. Many authors reported that quality of weld can be enhanced by optimize the factors i.e. current, electromagnetic force, surface tension. In order to control the size of droplet, rate of detachment and mode of metal transfer plays a vital role. Out of various mode of metal transfer, cold metal transfer has a extensive and promising performance in the application of ferrous to non-ferrous joining. Submerged arc welding (SAW) and Gas metal arc welding (GMAW) is more popular due to its inherent advantage such as faster metal deposition, deeper penetration, good surface emergence and high strength in the application of steel structural building, turbines, pressure vessels and for the joining of thick plates. In the present studies, work carried out by many authors on heat transfer and mass transfer for similar and dissimilar metal joining applications have been reviewed under various aspects.
