Welding

The weldability of Alleima® 6LR62 is good. Welding must be carried out without preheating and subsequent heat treatment is normally not required. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice.

For Alleima® 6LR62, heat input of <2.0 kJ/mm and interpass temperature of <150°C (300°F) are recommended.
