How Does the Welding Machine Function in GMAW?

The welding machine in Gas Metal Arc Welding (GMAW) functions by supplying a continuous flow of electric current and a steady feed of filler metal. The process begins when the operator triggers the machine, which generates an electric arc between the welding gun and the workpiece. This arc creates intense heat, melting both the electrode wire and the base metal.

The machine feeds the electrode wire through the welding gun at a controlled rate. As the wire melts, it forms a molten pool that joins the base metals together. Meanwhile, a shielding gas flows through the welding gun to protect the molten weld from contamination. The shielding gas surrounds the weld area, preventing exposure to the atmosphere.

The welder adjusts parameters such as voltage, wire feed speed, and gas flow rate to control the process effectively. This careful management ensures strong and clean welds. Overall, the welding machine in GMAW synergizes electric current, filler metal, and shielding gas to create high-quality welds efficiently.
