Experimental investigation of en24 steel properties by varying flux core arc welding parameters

Different type of welding used in joining the metals plays a major role in determining the change in properties. This research is about the after-effects of flux cored arc welding on EN 24 steel. This was chosen because of its high deposition rates and less skill required for operators to perform. In total 9 specimens were welded using flux core arc welding (FCAW) at 9 different parameters varying the welding current, arc voltage and gas pressure. Three different tests namely hardness, ultrasonic for flaw detection and tensile test for strength were performed to measure the deviation from the recorded values and the analysis of the obtained value shows that the parameters which are best suitable for EN24 FCA Welding are 180 amps, 20 volts, and 4 bar gas pressure. The three test results for all the parameter combinations are shown in further sections of the article.
