WEARtig Tool 55 is a tool steel TIG rod for cold and hot work tool steels, with a high weld metal hardness of 53 to 58 HRC.
You feed the filler into the pool by hand while the arc burns between the tungsten electrode and the weld, which suits deposits that need a smooth face. The rod is used in maintenance work, where worn dimensions are restored and surfaces reinforced. Previously sold as UTP A 73 G2.
- Classification EN ISO: 14700 S Fe8
- AWS classification: S Fe8
- Shielding gas: I1
Expect a network of shrinkage cracks in hard overlays, on working deposits this is normal, but it must not reach into the parent material. Set the gas post-flow long enough for the pool and the electrode to cool under the shield. Grind the tungsten tip along its axis and hold a short arc, otherwise the pool spreads.
