Welding is one of the most important processes in manufacturing and construction industries. Various categories of welding exist and there are many welding processes available from which and industrial engineers can select for a particular application. The fusion category include the arc welding processes, resistance welding and gas welding methods; the non-fusion or solid state include cold welding, forge welding, ultrasonic welding, friction welding, friction stir welding, resistance welding, diffusion bonding, and explosion welding. The high energy densities/low dilution welding method in this category are pulse arc welding (PAW), laser beam welding and electron beam welding. The choice of a welding process and the welding input parameters are determined by some factors. This review highlights the categories of welding, factors influencing the choice of a particular welding process for a given application, Various areas of application of these categories of welding were discussed and it also address the effect of some of these welding input parameters on the integrity and quality of weld joints. The goal is to achieve high-quality welded joints with desired bead geometry and performance while minimizing detrimental internal stress and distortion and the corrosion rate characteristics of these regions, are all demonstrably influenced by the selected welding parameters. In essence, this review underscores the critical role of precise process control in achieving optimal weld quality and mitigating potential drawbacks in the welding industry
