Recommended Welding Method

For optimal welding results, ER 5554 performs best with alternating current (AC) and pure argon as shielding gas. Proper surface cleaning before welding is necessary, both the joint and the welding wire should be free from moisture, dust, and contaminants to ensure a stable arc and strong weld integrity.
