TIG rod wire designed for welding dissimilar steels and those with 13% manganese content. Suitable for heterogeneous cold welding, without preheat, of carbon, stainless, wear-resistant and armor steels. It is also used as a cushion layer and cladding intermediary layers. Resistance to hot cracking is provided by the high manganese content. In some cases this wire may offer an alternative to high nickel weld metal in joints between cast iron and stainless steels. Used as a wear-resistant material of rails which work hardens from 200 to 400 HV. To be used under the shield of 100% Ar 98%.
