Classification method editing
1) According to its chemical composition, it can be divided into two categories; namely, iron-based surfacing welding wear wire and non-ferrous base surfacing welding wear wire. Each category can be divided into several sub-categories according to their chemical composition or microstructure. For example, iron-based surfacing welding wear wire can be divided into high-chromium alloy surfacing welding wear wire, tungsten carbide surfacing wear-resistant welding wire, etc. Non-ferrous-based surfacing welding wear wire can be divided cobalt-based surfacing welding wear wire and nickel base Surfacing welding wear wire.
2) According to the wire structure, it can be divided into solid wire and core (also known as tubular) wire.
3) According to the welding method used, it can be divided into gas shielded welding, submerged arc welding, flame surfacing, plasma surfacing and welding (welding) surfacing welding wear wire.
1) Cost savings. Surfacing a wear part to re-achieve the requirements can save 25%-75% of the cost compared to replacing the wear parts;
2) Improve the service life of the workpiece. Compared with the non-surfacing metal parts, the surfacing metal parts can increase the service life by 30% to 800% depending on the scope of use.
It has good anti-abrasive wear, impact wear resistance, adhesive wear resistance (intermetallic wear), high temperature wear resistance, corrosion resistance and resistance to composite wear of more than two types.
