China wholesale Hard-Facing D802 Soldering Data Factory - Hard-facing SAW welding wire and welding flux weld fabrication stuff – Honest Metal

Application & Standard

This hard surface WEAR-resistant hand electrode is mainly suitable for low impact, intense wear parts, such as civil construction machinery surfacing regeneration, especially dredging machinery, bucket, sand suction pump. Surfacing is a welding method in which the surface or edge of steel parts is fused with a layer of wear resistance, corrosion resistance, high temperature resistance and other characteristics of metal materials. To repair and improve the service life of parts, effective use of raw materials, improve product performance, cost control has obvious economic benefits. The standard of surfacing is very complex. It is necessary to adopt suitable welding wire according to different rules. Different surfacing processes should be used for different steel parts and surfacing electrodes to obtain satisfactory actual surfacing results.

Features

This is a low sodium hydrogen coating type surfacing electrode, high hardness, no need of heat treatment, can not continue cutting, good wear resistance. Wear – resistant correct operation process can ensure that all the skin can be melted into the molten pool through the arc during fusion welding. And weld core, substrate surface metal rapidly melting to produce a new wear-resistant alloy. At the same time, efforts should be made to improve the carbon content of the electrode on the premise of ensuring that the welding layer has excellent crack resistance. Promote the formation of various carbides, increase its wear resistance. For the parts that bear impact and abrasive wear at the same time in the work, such as the hammer head of the crusher, lining plate, cage rod, etc. The above welding layer is far from meeting the requirements of its working conditions, and a completely different operation process must be adopted.
