Heat flow in welding is mainly due to heat input by welding source in a limited zone and it subsequent flow into body of work piece by conduction. A limited amount of heat loss is by a way of convection and radiation. Local Heating and cooling of metal shrinkage on solidification and structural change on solidification cause temperature distribution. In the present work, authors have investigated the width of HAZ with various process parameters like heat input & welding speed. In manual metal

In manual metal arc welding (MMAW), selecting appropriate values for process variables is essential in order to control heat-affected zone (HAZ) dimensions and get the required bead size and quality. In this study, the effect of various welding parameters on the weldability of Mild Steel specimens having dimensions 125mm× 75mm× 5 mm welded by manual metal arc welding (MMAW) for single V-Butt joint were investigated. The welding current, arc voltage, welding speed, heat input rate are chosen as welding parameters. The effect of these parameters on the size of Heat affected zone is investigated.
