Optimization of Gas Metal Arc Welding Process Parameters on Structural Steel Plates by Taguchi Method.

Steel welding is one of the most contentious academic topics nowadays. Shielded metal gas techniques’ impact on AISI1040 steel have been qualitatively investigated (MIG and TIG). The experimental layout must be developed using Taguchi approach. Arc voltage, arc current, speed, nozzle to work distance, pressure all found an effect weld quality. backing plate’s thickness as well both matter. A trial design based orthogonal array used create weldments. To determine how successfully weldments were welded, a set tests are performed them. ANOVA assess suitability data. computed result contribution from each parameter obtain optimum values for fault minimization. Weldments examined angle beam test, outcomes assessed ultrasound testing (UT). presence faults in tested specimens, such LOP, LOF, Blowholes, Cracks.
