Welding heat input is the most important factor in any fusion welding process which is basically an outcome of the combination of different process variables. It offers significant contribution towards the quality of weldment particularly in weld zone and heat affected zone. Manual Metal Arc Welding (MMAW) is the widely used welding process in the industries because of its low cost and versatile applications. The consumable electrodes with flux coating are used in this welding process which produces shielding gases to protect the weld zone from atmospheric contamination during welding. A lot of research work has been performed in order to investigate the effect of process parameters on the weldment of mild steel plates developed by MMAW process. In this study, an effort has been taken to understand the influence of welding heat input in weld zone and heat effected zone in butt joint of manual metal arc welded mild steel plates with a variation in process parameters.
