Study Notes
Gas Metal Arc Welding (GMAW)
- GMAW stands for Gas Metal Arc Welding.
Process Overview
- The external gas in GMAW protects the arc and molten metal from atmospheric gases, such as nitrogen and oxygen.
Wire Feeding
- A continuous wire electrode is fed from a spool to the arc zone in GMAW.
Process Characteristics
- GMAW is considered a semi-automatic process because the wire is continuously fed, but the gun movement and weld direction are controlled manually.
Wire Specifications
- The range of wire diameters used in GMAW is typically from 0.6 mm to 2.4 mm.
