Dual Shield 69 is ESAB's new all-positional, low hydrogen rutile cored wire for use with Ar/CO2 shielding gas mixtures. Designed for high integrity welding of high strength steels this wire produces tough weld metal down to -60o C and meets the low diffusible hydrogen grade of H4. High strength steels are increasingly being used as they offer the designer the possibility of making lighter, higher performance structures with good overall cost effectiveness together with lower environmental impacts. The use of high-strength steel can mean lower fabrication costs, increased payloads, more durable products, more effective space utilisation and increased safety.
