ESAB Weld 7018L
The ESAB Weld 7018L is a high-quality, iron powder-coated stick electrode designed for welding mild and low-alloy steels. It not only offers exceptional weldability, but it also ensures smooth bead appearance and minimal spatter. This electrode operates best with DCEP (Direct Current Electrode Positive) and provides excellent deposit rates, making it ideal for general-purpose welding across various industries.
In addition, Weld 7018L exhibits strong mechanical properties, delivering good ductility and high notch toughness at both low and elevated temperatures. With low hydrogen content (< 5 ml/100g), it further minimizes the risk of hydrogen-induced cracking. The moisture-resistant coating guarantees consistent weld quality, even under challenging conditions.
