Low Alloy

OK 73.15 is a basic electrode with very good welding characteristics. Its exceptional weldability is ideal for multiple applications including Pipe. The electrode has a classification of AWS 8018-C3 H4R and gives a weld metal alloyed with about 0.9% Ni. It fulfils impact requirements down to - 50 °C. The low moisture absorption coating gives less than 4 ml diffusible hydrogen / 100 g welded metal. Weld metal recovery is above 120 % for the main diameters. OK 73.15 is HIC test compliant as per NACE TM0284 & SSC test compliant as per NACE TM0177.

Ni-, Mo-alloyed, copper-coated wire for Submerged Arc Welding. Preferably in combination with OK Flux 10.62. For high strength steels with minimum yield strengths up to 550 MPa (in AC current up to 620 MPa), low temperature steels, fine grained steels, etc.

Coreshield 71T-8 OS is a self-shielded flux cored wire designed to weld critical structural applications such as TKY joints for offshore construction, pipe structures, bridges and storage tanks. It is designed to provide excellent low temperature impact toughness down to -40 degrees C. whilst maintaining great arc characteristics, high welder appeal and easy slag removal in all welding positions.

The non copper coated OK AristoRod 13.09 is a low-alloyed, molybdenum (0,5% Mo), solid wire for GMAW of creep resistant steels of the same type, such as pipes in pressure vessels and boilers with a working temperature of up to 500 °C. The AristoRod wires are suitable for operating at high currents with maintained disturbance free wire feeding giving a stable arc with a low amount of spatter. OK AristoRod 13.09 delivered in the unique Esab Octagonal Marathon Pac is excellent in mechanised welding applications.

An all-positional rutile cored wire for pipe welding of steels with a minimum strength of 550 MPa, for use with M21 shielding gas.

Cellulosic coated electrode for welding of low alloy steel pipes. Designed for vertical down welding, the deep penetrating arc provides good performance. Suitable for welding pipe steel types API 5L X52 to X60.

An positional rutile cored wire for use with M21 or C1 gas, providing very good toughness down to -40°C. The 1.2mm diameter is all-positional except vertical down.

Cellulosic coated electrode designed for low alloy steel. Deep penetration welding in all positions, especially designed for vertical down welding of high strength pipelines. Provides high economic benefits compared to welding vertical up. Recommended for welding pipe-lines of API 5LX: X60- X70.

A copper coated, low alloyed, molybdenum (0,5% Mo) rod for GTAW of creep resistant steels of the same type, such as pipes in pressure vessels and boilers with a working temperature of up to about 500 ﾰC.

A metal cored wire for the welding of high strength steels (>690 MPa) with excellent sub-zero toughness down to -60 degrees C and low diffusible hydrogen levels. Suitable for welding with Ar/CO2 gas mixtures.

A copper coated, low-alloyed, nickel-molybdenum-titanium (1,0 % Ni, 0,3% Mo, 0,1% Ti), solid wire for GMAW of low alloyed high tensile strength steels and fine grained steels for use in constructions such as bridges, off-shore and hoists with a minimum yield strength less than 610 Mpa. The alloy has good impact properties down to -60ﾰC. When used in mechanical pipe welding in narrow groove, yield strngths in excess of 700 MPa may be obtained, allowing overmatching of X80 pipeline steel.

An all-positional rutile cored wire with good toughness down to -60 °C for the use with M21 shielding gas. Diameters less than 1.4mm are all-positional except vertical down.

The non copper coated OK AristoRod 13.26 is a low-alloyed, nickel-copper (0,8% Ni, 0,45% Cu), solid wire for GMAW of weathering steels, such as COR-TEN, Patinax, Dillicor etc. According to NACE it would be acceptable to use these welding consumables, since the nickel content is below the maximum acceptable level, 1 % for sour gas applications. One other requirement from NACE is the maximum hardness of the deposited weld metal, which must not exceed 22 HRC. The weld metal composition and mechanical properties also make this product suitable for welding high strength steels with a minimum yield strength less than 470 MPa. The AristoRod wires are suitable for operating at high currents with maintained disturbance free wire feeding giving a stable arc with a low amount of spatter. OK AristoRod 13.26 delivered in the unique Esab Octagonal Marathon Pac is excellent in mechanised welding applications.

Ni-, Cr-, Mo-alloyed, copper-coated wire for Submerged Arc Welding. Preferably in combination with OK Flux 10.62. For high strength steels with minimum yield strengths up to 690 MPa, low temperature steels, fine grained steels, etc.

A metal cored wire containing 0.5% Mo for submerged arc welding.
