Weldcast Wearplates
Duraweld Composite Wearplates
Wearplate Technology was first introduced in our country by none other than DURAWELD in the year 1991.
The Wearplate Technology
Wearplate manufacturing is the highly specialized process where in mild steel base plate is Weld Cast by simulataneous blending of alloy wires and alloy carbide constituents, which ensures maximum possible carbide concentration and minimum dilution. The Wearplate provides muscles on your metal/ machinery components to Combat wear very efficiently and econmically. the composite wearplates is weld cast by chronium and other mix Alloy Carbides to achieve properites Viz. Severe abrasion, moderate to heavy impact and heat resistance in one single plate without sacrificing very high initial hardness.
Fixing
DURAWELD WEARPLATES can be welded to any existing metal structure by welding the mildsteel base with low hydrogen or stainless steel electrode depending on the metal structure. Duraweld WEARPLATES are provided with countersunk holes or plug weld holes by a specially designed Metal Arc Disintegrator System. Studes are welded by stud welding machine on the mild steel base of DURAWELD WEARPLATES.
Appearance
The wear resisting side of Duraweld Wearplate appear as 65mm, smooth wide weld bands. These bands are fused together to form essentially a flat, even, continous ripple free surface. Due to the hard characteristic of the carbide layer and the contraction stresses, during the manufacturing welding process, cracks develop at the right angles to the surface but donot penetrate beyond the carbide layer.
Extreme Abrasion/ Impact Resistance
Duraweld wearpaltes, own its abrasion Resistance to Chronium Carbides/ Alloy Carbides Concentration of 45% to 60% in weld cast deposite and impact Resistance to Ductile Mildsteel Base. High Carbide Concentration is due to ROBOTIC Weld Cast process which ensures very low dilution levels.
Cutting and Forming
DURAWELD WEARPLATES are usually cut by air plasma<, argon/ nitrogen plama cutting machines. They can be cut with gouging/ cutting electrodes or by carbon arc. The quality of cut on DURAWELD WEARPLATES is best with plasma equipment.
DURAWELD WEARPLATES can be cld rolled for large diameters or formed by way of brake press for smaller diameters.
