During arc welding of zinc coated steel, or galvanized steel, the zinc coating vaporizes at 1600°F (871°C). This temperature is much lower than steel’s melting point of 2800°F (1538°C). Controlling heat input and welding speed is essential to manage zinc vaporization and ensure good welding quality. Best practices for arc welding zinc-coated steel include thorough … Read more

Flux cored arc welding (FCAW), or dual shield welding, is a semi-automatic process. It uses a continuous wire electrode and a constant-voltage power supply. FCAW offers advantages like versatility and efficiency. It is ideal for applications in construction and manufacturing, especially when compared to MAG welding. In FCAW, an electric arc forms between the continuously … Read more

In arc welding and cutting operations, use electrical tape for temporary repairs on minor cable damage. Ensure the cable is not deeply cut to prevent exposing wires. Wrap multiple layers tightly around the damaged section. For permanent solutions, replace the cable. Always prioritize safety by using shielding and noncombustible screens for employee protection. Using electrical … Read more

Arc welding is a process that joins metals using an electric arc. The main types are: Gas Metal Arc Welding (GMAW/MIG), which uses a consumable electrode; Gas Tungsten Arc Welding (GTAW/TIG), which uses a non-consumable electrode; Shielded Metal Arc Welding (SMAW); and Flux-Cored Arc Welding (FCAW). Each type has unique applications. SMAW, also known as … Read more
