Welding tool is a process in which materials with certain properties are clad on the surface of the workpiece by welding. The difference from welding is that surfacing welding is not for connecting workpieces, but for strengthening the surface properties of workpieces to obtain cladding layers with special properties such as wear resistance, heat resistance, corrosion resistance, etc. resulting in insufficient size).
Features of CBN welding tools:
(1) The bonding between the welding layer and the base metal is metallurgical bonding, with high bonding strength and good impact resistance;
(2) The composition of the welding layer metal is related to The performance adjustment is convenient; the commonly used electrode arc welding surfacing electrode or flux-cored electrode is very convenient to adjust the formula, and various alloy tools can be designed to meet the requirements of different working conditions.
(3) The thickness of the welding layer is large. Generally, the welding layer is adjusted within 2-20mm, which is more suitable for severe wear conditions.
(4) Cost saving and good economy;
(5) Since the welding technology is to increase or restore the size of the parts by welding, or to obtain an alloy layer with special properties on the surface of the parts, so For those who are proficient in welding and surfacing technology, it is not difficult and has strong operability. It is widely used in parts repair and manufacturing in metallurgy, mining, electric power, agriculture, petroleum and other industries.
