The Wearplates Technology |
Weraplate technology manufacturing is the highly specialised process wherein mildsteel base plate is weld cast by simultaneous, blending of alloy wires and alloy metal constituents, which ensures maximum possible carbide concentration and minimum dilution. The Weraplates provides muscles on your metal/machinery components to combat wear very efficiently and economically. We at DURAWELD Produce the WERAPLATES very much the same way at they are manufactured. (viz. U.K, Australia, Germany and U.S.A. )
The composite weraplates where in the mildsteel base is weld cast by chromium and other Alloy Carbides to achieve properties viz. severe abrasion, moderate to heavy impact and heat resistance in one single plate without sacrificing very high initial hardness. |

Extreme Abrasion / Impact Resistance |
Duraweld Weraplates, own its abrasion Resistance to Chromium Carbides / Alloy Carbides concentration of 45% to 60% in hard overly and impact resistance to ductile Mildsteel base. High Carbides Concentration is deu to ROBOTIC Weld cast process which ensure very low dilution levels. |

Appearance |
The wear resisting side of DURAWELD WERAPLATES appear as 65mm, smooth wide weld bands. These bands are fused together to form essentially a flat, even, continuous 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 do not penetrate beyond the carbide layer. |

Cutting & Forming |
DURAWELD WERAPLATES are usually cut by air plasma, argon / nitrogen plasma cutting machines. They can be cut with gouging / cutting electrodes or by carbon arc. The quality of cut on DURAWELD WERAPLATES is best with plasma equipment.
DURAWELD WERAPLATES can be cold rolled for large diameters or formed by way of a break press for smaller diameters. |

Fixing |
DURAWELD WERAPLATES can be welded to any existing metal structure by welding the mild steel base with low hydrogen or stainless-steel electrode depending on the metal structure.
DURAWELD WERAPLATES are provided with countersunk holes or plug weld holes by a specially designed Metal Arc Disintegrator System.
Studs are welded by stud welding machine on mild steel base of DURAWELD WERAPLATES. |
