UTP 402-G is a gas shielded metal cored wire recommended for build-up, crack repair and buffer layers laid before hardfacing.
It is fed continuously from the feeder and welded under shielding gas. The wire is meant for hardfacing surfaces exposed to abrasion and goes into maintenance work, rebuilding dimensions and strengthening worn surfaces.
- Classification EN ISO: 14700 T Z Fe10
- AWS classification: T Z Fe10
- Shielding gas: M13, M12
- Diameters: 1.6 mm
- Hardness of deposit: 150 HB
Remove the fatigued and hardened top layer before hardfacing, an overlay laid on worn material chips off. Clear the residue after every bead and keep the wire in dry storage. Check how many layers you need to reach the target hardness, the first layer always mixes with the base material. The gas choice affects the shape of the face and the amount of spatter, so keep to the mixture given in the classification.
