Metal-cored welding wire for high-strength steel

Metal-cored welding wire for high-strength steelEsab Welding & Cutting Products (www.esab.com) has launched Coreweld 55 LT H4, the newest product in its series of Coreweld metal-cored wires designed for welding high-strength steel (HSS).

Conforming to AWS A5.36 E91T15 M21A6-G H4 and EN ISO 18276-A T 55 6 Z M21 2 H5, Coreweld 55 LT H4 offers a “typical impact toughness of 110J” at -60°C, a yield strength greater than 550MPa, a tensile strength of 670MPa and less than 4ml of diffusible hydrogen per 100gm of deposited weld metal.

Its applications include semi-automatic and automatic welding of bridge members, crane arms and other lifting equipment, mobile machinery, and hoppers and containers.

Neil Farrow, Esab’s global product manager for cored wires, said: “Coreweld 55 LT H4 is a fine-tuned lower-alloy wire (1.3% Ni) that improves welder appeal with a smooth stable arc at high welding speeds and good ‘wet-out’.

It also minimises spatter and silica islands, speeding post-weld clean-up. Moreover, it does not need a copper coating, eliminating the flakes that can block torch liners and cause down-time.”

Coreweld 55 LT H4 is produced in 1.2, 1.4 and 1.6mm diameters, and it is available in 16kg packages as well as a 255kg Esab Marathon Pac. Esab now offers five European-produced Coreweld metal-cored wires.

Mr Farrow said: “Coreweld HSS wires deliver sub-zero toughness and offer high deposition rates, high deposition efficiencies, faster travel speeds, excellent penetration and ease of use.

“Indeed, deposition rates can be as high as 8.0kg/hr. Metal-cored wires also offer many other efficiencies compared to solid wires, including little to no post-weld clean-up, excellent sidewall fusion and root penetration, the ability to bridge gaps without burn-through, and the ability to weld thin materials at high amperages without burn-through.”
