Wisdom's Solutions for the Valve Industry

Wisdom’s industrial line of hardfacing welding consumables are widely used in the valve industry. Due to the requirement of wear and corrosion resistance in the valve, our hardfacing materials are applied to its surface. Typical markets for this application are power generation, oil & gas, chemical, mining, and refining.

Valve parts are coated with Wisdom’s WD cobalt-based rod, which is continuously casted. The rod is used for Tungsten Inert Gas welding operations or Oxy-acetylene welding process as well as automated or robotic welding. Automation system has significant merit than OAW and TIG, helping to reduce downtime, decrease labour force, and diminish the waste of the valuable alloys. The rod can also be covered for Shielded Metal Arc Welding processes.

Wisdom’s WD can be coated as a surface for stainless steel, carbon steel and nickel-based alloys.  For example, valve seats and plugs can be hardfaced with WD-6, with chemical composition of Co (Bal.), Cr (27-32), W (4-6), and C (0.1-1.4) . This grade alloy will generate a wear and corrosion resistant coating elongating the time of use. Many valves involving high pressure and temperature steam require alloys to withstand their harsh operating circumstance.

Below are typical valve applications

  • Plugs
  • Gates
  • Seats
  • Stems
