• | Single process from root to cap |
• | Up to 500 mm per minute manual welding length |
• | More than 500 mm welding length per minute with Automation |
• | Less cleaning considering the low oxidation and clean welding environment |
• | Bevel preparation less critical due to better control over energy input |
• | Use of standard MIG filler wire, lower inert gas consumption |
• | Welding of different wall thicknesses in one pass |
• | Increased layer thickness per pass |
