What BÖHLER DMO TIG rod is used for

BÖHLER DMO is a TIG rod for welding creep-resistant CrMo steels. It is used on boilers, steam pipelines, refinery installations and parts working at elevated temperature.

The rod joins grades such as S235JR, S275JR, S275N, S275M, P195GH, P295GH and P195TR1, along with related materials. The copper coated surface improves current pick-up in the contact tip and smooth feeding, and the rod works in power plant on superheaters, headers and pressure pipework.

  • Classification EN ISO: O IV
  • AWS classification: R60-G
  • Diameters: 1.6 / 2.0 / 2.4 / 3.0 mm

Watch the hydrogen level, dry consumables and a preheated groove are your basic protection against cold cracking. Keep the rod inside the gas shield even after you lift it from the pool, a cold oxidised end will contaminate the next drop. Set the gas post-flow long enough for the pool and the electrode to cool under the shield. Thinner diameters suit root runs and thin sheet, thicker ones suit filling.
