Research on the Performance and Process of Fe/Cr-V – WC Surfacing Welding Layer on Weapons Parts Department

Abstract:

In this paper,a Fe/cr-v - WC flux-cored wire welding alloy which used in weapons parts wear surfacing is developed. By the analysis of the average hardness of surfacing welding layer, the wear weightlessness and the microstructure, the wear resistance properties of surfacing welding alloy is studied. And the cored in alloying elements Cr, WC, Mo and V on the influence law of hardness and wear resistance of surfacing welding layer are systematically discussed, So as to the best alloy element content in the cored is determined. Results are showed that Cr element content is 5.5% ~ 5.5%, the content of WC powder is 3.9% ~ 4.2%, at 1.6%, content of Mo element V element content is within 3.2%. with the Fe/Cr - WC flux-cored wire welding alloy ratio appropriate, weapons parts welding layer has good hardness and abrasion resistance.
