Study Notes
Shielded-Metal Arc Welding (SMAW)
- The coating of the filler rod in SMAW is made of flux, which protects the arc and molten metal from the atmosphere.
- SMAW is considered versatile because it can be used in various applications, such as repair and maintenance work, but not automatable because it requires manual skill and dexterity.
Gas Metal Arc Welding (GMAW)
- The purpose of the shielding gas in GMAW is to protect the arc and molten metal from the atmosphere, preventing porosity and oxidation.
- The consumable wire electrode in GMAW is typically composed of a solid wire made of the desired metal alloy.
Post-Welding Process in SMAW
- After welding, the melted flux or slag at the weld in SMAW must be chipped off to reveal the weld surface.
