Mastering this technique ensures high structural integrity and prevents common welding defects.
E7018 for strength, E6010 for deep penetration. Amperage: Lower than flat position to prevent sagging. 2. Gas Metal Arc Welding (GMAW / MIG) Gas Mix: 75% Argon / 25% CO2cap C cap O sub 2 for carbon steel. Wire Feed: Consistent speed prevents cold lapping. Travel Technique: Push technique for cleaner bead profile.
