Welding Rods & Electrodes
Kennametal Stellite produces one of the industry’s most extensive portfolios of hardfacing weld rods and electrodes. These products produce claddings for extreme applications including valves & pumps for oil & gas, cutting tools & saw blades for timber, crusher jaws & dredge buckets for mining and turbine blades for power generation.
All of Kennametal Stellite’s rods and electrodes are cast using a multi-strand continuous casting process and are available in a wide range of diameters, finishes and lengths.
They can be used in a variety of welding techniques, including TIG, GTAW, Oxyacetylene, MMA and SMAW.
- TIG (GTAW): TIG (Tungsten Inert Gas), also known as Gas Tungsten Arc Welding (GTAW), the electrode, the arc, the rod and the weld-pool are protected from the atmosphere with an inert shielding gas. The advantages of TIG include simple manual operation and good control of the welding arc.
- Oxy-Acetylene: Oxyacetylene welding (aka gas welding) is a process that uses a combination of oxygen and acetylene gases to create a high-temperature flame to melt a small amount of the base metal and a hardfacing rod, allowing a cladding to form.
- MMA (SMAW): MMA welding (aka Manual Metal Arc welding or Shielded Metal Arc Welding (SMAW)), is a process that uses a electrode coated in flux to create a cladding. The flux on the electrode forms a protective gas shield, preventing oxidation or contamination from the surrounding air.
