Product description
– Copper-coated tubular flux-cored wire for gas-shielded welding.
– Nickel-molybdenum alloyed deposited metal offers excellent low-temperature mechanical properties
– Fast-solidifying rutile slag facilitates welding in all positions.
– Suitable for single- and multi-pass joining of CMn and fine-grained steels.
– Suitable for the penetration pass on ceramic substrates.
– Very good workability, no moisture pick-up, excellent unwinding properties.
– Diffusible hydrogen content ≤ 4 ml per 100 g of metal deposited.
– Used with mixed gas.
