HARDFACING ELECTRODE
Desgastec Triten Products
The Desgastec Triten range of tubular electrodes has been developed specifically for wear resistant hardfacing. The properties of the alloys making up the tubular electrode range have been engineered to provide extended service life at ambient and elevated temperatures in aggressive environments involving abrasion, erosion, and impact. In addition to hardfacing sections of plant, Desgastec Triten T-23 and Desgastec Triten T-34 can be used on compatible wear resistant overlay plates.
Tubular electrode design-less distortion
The special tubular construction of Desgastec Triten electrodes electrodes has many practical advantages over extruded welding rods and hardfacing wires. They require low operating currents, which produces less heat leading to less base metal penetration. This gives reduced distortion, minimizes risk of burn-through, and less dilution of the alloy overlay.
Low operating currents also allow hardfacing on thin sections right up to and around the edges of auger flights, scraper and mixer blades, and other worn sections.
Deposition rates can be increased by introducing a second electrode into the weld pool, for example, during cast welding procedures used to protect bolt heads, etc.
Reliable and efficient on-site performance
Unlike comparable extruded welding rods, the outer coatings of Desgastec Triten tubular electrodes are moisture resistant. They do not require special storage conditions, will not flake when damp, and resist mechanical damage. All electrodes can be used direct from the packet, without pre-baking with no need for de-slagging between runs, and application is fast and efficient.
A unified stub end size enables all electrodes to be used in a standard holder. Hardfacing can be carried out using most portable AC or DC welders.
