Nowadays the automotive, aviation, and space industries increasingly seek low-cost, high-strength, lighter, and
more efficient welding processes. CMT welding, which gives these qualities, shines out when joining aluminum
alloys. In the investigation, cold metal transfer (CMT) was used to join AA6061-T6 sheets with AlMg4.5Mn
filler wire. The mechanical characteristics and microstructures of welded joins generated at various torch
angles, shielding gas flow rates, and welding speeds were examined. The Taguchi experimental design approach
was used to determine the most optimal process parameters. The optimum levels for tensile strength were
determined as A2-B2-C1 (70° - 12 L/min - 40 cm/min) and for hardness as A2-B1-C1 (70° - 8 L/min - 40
cm/min). In addition, the contribution of the process parameters to the findings was evaluated using ANOVA.
The experimental study revealed that the most effective parameters on mechanical properties were welding
speed, torch angle, and shielding gas flow rate. The mechanical characteristics decreased as the welding speed
increased. High gas flow rate and torch angle were shown to have a negative impact on mechanical
characteristics.
