Low-alloy wires offered for all-position welding

ESAB Welding & Cutting Products has introduced two new wires to its Dual Shield II series of mild steel and low-alloy flux-cored welding consumables. According to the manufacturer, the wires offer excellent welding performance in all positions with high deposition rates and efficiencies. They produce a weld bead with almost no ripple and very little spatter, the company reports.

4130 SR is an all-position, flux-cored wire for welding low-alloy, high-strength steels such as 4130. It is suitable for offshore oil and gas topsides and platforms requiring high corrosion resistance with stress-relieved high strength and low-temperature impact toughness properties. The consumable offers mechanical properties in the as-welded and after-PWHT conditions and meets ANSI/NACE MR0175/ISO 15156-1.

70-Ni1 H4 is designed for use with 75 percent argon/25 percent CO2 gas protection. The flux-cored wire provides low-temperature toughness in both as-welded and stress-relieved conditions. It produces diffusible hydrogen levels of less than 4 ml/100g over a range of welding parameters. The smooth arc, fast-freezing slag, low spatter levels, and simplified slag release make the wire suitable for welding steel plate in all positions, states the manufacturer.
