Copper coated welding wire for steel constructions with very high requirements for mechanical characteristics and weldability.
The perfect spooling, the uniform copper coating, the low torsion in the wire, the small tolerances on the diameter and the high degree of purity, guarantee an optimal and constant welding quality.
The mechanical characteristics are higher than those of most lime type electrodes.
For boiler work, machine building, ship building, sheet metal welding etc…
Structural steel: S185, S235 - S355 (EN 10025).
Boiler plate: P235GH, P265GH, P295GH (EN 10028-2).
Pipe steel: P235T1 - P355N (EN 10217-1); P235T2 - P355N (EN 10217-3); StE290.7TM - StE480.7TM (EN 10208-2).
API steel: X42 - X70.
Fine grain steel: StE355 - StE460 (EN 10028-3).
Hull steel grade A, B, D, E, AH32 - EH36.
Cast steel GS38, GS45.
BS 4360 grades 40, 43 and 50.
Gas flow in short arc, 8 to 10 litre/min (17-21 cu.ft./hr) and in spray arc, 12 to 17 litre/min (25-36 cu.ft./hr).
When welding outdoors protect the welding area against wind and increase the gas flow.
You will obtain the highest mechanical strength in short arc (lower burn off of alloying elements).
