The wear resistance of the standard and composite carbide series of welded surfacing plates from Welding Alloys exceeds that of quenched and tempered wear-resistant steels.
Such features are achieved by producing extremely fine and uniformly distributed chromium and composite carbides throughout the thickness of the welded layer. In-house developed technology and sophisticated equipment ensure that Welding Alloys' products are unique because they:
In addition to wear resistance, Welding Alloys also offers specially designed materials to prevent material loss due to temperature rise, high impact and corrosion, and the mixing of all these wear mechanisms.
This model is a heavy-duty composite covering wear plate with the following characteristics:

Welding Alloys realizes that the requirements of each user are unique, and all ready-made products cannot always meet the requirements of all customers. Therefore, Welding Alloys also provides personalized surfacing solutions to meet specific requirements and environments.
For example, the requirement can be a stainless steel surfacing layer on carbon steel or a wear-resistant surfacing layer on heat-resistant steel, wear-resistant steel or stainless steel.
When producing composite covering materials from welding alloys, the dilution and cooling rates are very carefully controlled. High dilution rate will affect the final welding chemistry, even though the hardness may still be within the acceptable range, the weld metallurgy may not be acceptable.
For this reason, hardness should not be regarded as a direct measure of wear resistance, but should only be used as a guideline in the testing process of hard-facing surfacing plates.
ASTM G-65 abrasion test (independent laboratory). The image above reflects the results of the ASTM G-65 abrasion test conducted by an independent laboratory. The results compare the wear life of various tested products. For example, the life of Hardplate™ 100 is 4 times longer than that of 500 BHN quenched and tempered material, and the life of Hardplate™ 300 is 7 times longer. Image source: Welding Alloy Co., Ltd.
Welding Alloys uses special welding consumables and suitable welding procedures to manufacture complex automated welding equipment. This ensures the best weld metallurgy while limiting the dilution to a minimum, thus providing the maximum possible carbide level distributed throughout the thickness of the surfacing layer.
Most of Welding Alloys' plate products are manufactured using managed welding bead and oscillating bead technology. Both of these welding techniques have been upgraded to ensure that the weld metal metallurgy and surfacing composition are conducive to the formation and distribution of carbides throughout the surfacing thickness.
Users can refer to the comprehensive workshop and sheet processing manuals as required to learn more about sheet processing, forming, cutting, welding, assembly options, etc.
All sheet products provided by Welding Alloys Ltd can be heat treated by laser or plasma cutting and connected by welding. The wear resistance of the heat-affected zone is not affected by any of these thermal processes, thus effectively preventing the preferential wear that is often observed in these areas when using quenched and tempered materials.
