Summary, etc. The present study focused on evaluating mechanical and microstructural properties of Gas Metal Arc (GMA) welded High Strength Low Alloys (HSLA) steel weldments at different heat inputs. Heat input plays a significant role in influencing welded joints' mechanical properties and microstructure. Nine different values of heat input were considered and the range of heat input value was from 1.89-2.61Kj/mm. From the results it was found that on increasing the heat input in the form of input parameters, the average Ultimate Tensile Strength (UTS) was increased and then decreased but at the same time grain coarsening in microstructure was also observed. From the rest result, it was also observed that on increasing the heat input value toughness of weldment also increases.<br />
