In this welding the arc should be steady and uniform Literature review report that comprehensive studies of Hardness had been carried out by so several authors, tranquil there is general lack of empirical data on different types of Hardness mostly for butt weld (v-groove) joint.
EFFECT OF WELDING TECHNIQUES (GTAW & SMAW) ON
Two different Welding techniques (SMAW, GTAW) were applied to mild steel of ASTM grade SA 516 Gr. 70 which is frequently used in boiler and pressure vessel etc. Welding was carried out according to commercial practice under controlled welding conditions. For each welding techniques three portions i.e. base metal, HAZ and weld zone were examined microscopically on optical microscope.EXPERIMENTAL INVESTIGATION TO DETERMINE In this thesis MIG welding is performed on the Mild steel pieces by varying the welding current at weld speeds of 3.2mm/sec, 3.7mm/sec and 4.2mm/sec. The welding currents are 150amps, 200amps and 250 amps. Hardness and tensile tests are performed on the pieces. The brinell hardness of mild steel is 120HRB. By observing the hardness test results, the hardness is decreased after welding.Experimental Investigation on Welded Joints of Dissimilar mild steel hardness specimen WeldingA perfect welded joint can be achieved by using mild steel filler for welding mild steel with stainless steel. In all scenarios, the welded joints have high hardness and are brittle in nature. Welding parameters are vital when welding dissimilar steels.
