Condiciones de uso
Prepare the casting defect to be repaired, preheat the piece to 550-650°C, keep this temperature during welding, use a current as high as possible, without overheating the electrode. Assure that sufficient base metal is melted to get a good bonding. When welding over the hot slag don’t move to fast with the arc to avoid trapped slag. After welding a PWHT, 2h at 900°C followed by 4h at 700°C and slow cooling in the furnace, insures a colour matching deposit and a regular hardness, even in the heat affected zone.
