Procedures

• Clean the weld area thoroughly. Base metals heavier than 3mm (1/8") should be beveled at a 75° angle. Pre-heat up to 200°C. Hold electrode almost vertical to work piece and strike arc by lightly drawing electrode on work piece or with copper starting block. Maintain short arc and remove slag between passes. Back whip any craters. Allow to cool slowly. Chip slag before quenching. 

Applications

• Aluminium, alloyed with copper, silicon and magnesium
• Joining dissimilar grades of aluminium
