3.4.1 GMAW welding, to analyze the hardness value. Yield point, tensile strength and elongation percentage 1. cutting stainless steel with mechanical saws, tool coolant with water 80mm 65mm * size and making a neat, sharp needle, delete. 2. place the work piece in position per v-1G tha rap. 3. adjust the variables in welding according to the welding current, like in the level. Welding speed Enter the welding wire speed in welding angle The gas flow rate and the Ark cover 4. cleaning the pieces at the joints to remove dirt. 5. place the workpiece flat on the welding in position, after Pier pads with workpiece clamping work jigs. 6. open the gas flow, covered later on, behind the work piece at the trial of 15 l/min. 7. connect the workpiece. Welding workpiece, use a stainless steel Welding workpiece in welding process with GMAW tha rap from the beginning until the end plate to the workpiece. 8. after welding is finished, leave the work piece. Bring the workpiece to be cleaned and brought to the temple measured strength and elongation percentage. 9. when a change in a variable to adjust the gas cover. Value flow in the weld and the welding wire speed to replenish.
