Parameters of hardfacing layer of wear-resistant electrode
Appearance inspection and mechanical properties of wear - resistant welding surfacing layer
Wear-resistant electrode surfacing after surfacing, can be used to visually detect whether cracks, pores, trachoma. Use calipers to check whether the appearance size meets the technical requirements. Mechanical properties tests include determining the hardness, tensile strength, ductility and impact toughness of overlay metals, as well as wear, heat and corrosion resistance of the overlay.
Surfacing layer machining
The quality of surfacing welding electrode surfacing metal according to process requirements for machining. Due to the high hardness of surfacing metal, with the general turning tool can not be processed, you can use grinding or thermal power processing.
