Final answer:
The statement is true; the GMAW process can indeed be used in both semi-automatic and automatic modes, with the welder controlling the welding gun manually in the former and machinery taking over in the latter.
Step-by-step explanation:
The statement that the GMAW process can be used either semi-automatically or automatically is true. GMAW, or Gas Metal Arc Welding, allows for both modes of operation. In semi-automatic GMAW, a welder manually controls the welding gun and feeds the wire at a steady rate, but the welding power supply remains controlled automatically. Whereas, in automatic GMAW, both wire feeding and the movement of the welding gun are controlled by machinery or robotic systems, which allows for continuous welding without manual intervention.Welding itself is a critical fabrication process that has been developed over thousands of years, from traditional forge welding performed by blacksmiths to modern techniques employing various forms of energy such as gas, electricity, and lasers to join metal materials with solder and heat.
The GMAW process, also known as Gas Metal Arc Welding, can be used both semi-automatically and automatically. In semi-automatic GMAW, the welder manually operates the welding gun while the welding wire is automatically fed into the weld pool. In automatic GMAW, the entire welding operation is mechanized and controlled by machines or robots.
