Abstract

The invention provides a spiral blade wear resisting layer alloy overlaying process. Rust impurities on the end surfaces of spiral blades and in nearby welding areas are removed; transition layers areoverlaid along the end surfaces of the spiral blades by using ERNiCrMo-3 nickel chromium molybdenum welding wires through argon arc welding; during welding, narrow beads and short arcs are adopted without swinging; the welding current is 80-85 A; the inter-bead temperature is not higher than 130 DEG C; the overlaying layer number is two beads in each layer; the continuous welding is adopted; thewelding directions of two beads are opposite; the overlap quantity of the latter bead is one half of welding lines of the previous bead; welded parts are naturally cooled; the spiral blades are preheated to 200-250 DEG C; Stellite cobalt base alloy cladding layers are overlaid; during overlaying, the welding current is 75-80 A; the inter-bead temperature is not lower than 200 DEG C; the welding direction between the beads is reciprocating bead-by-bead welding; and welding joints between the welding beads are staggered. The service life of the blades can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of spiral blade welding, in particular to an alloy surfacing process for a wear-resistant layer of a spiral blade. Background technique [0002] The farther the blade is from the drive shaft, the greater the force and the greater the edge wear of the blade. The process of depositing one or more layers of metals of the same material or different materials on the surface of mechanical parts by welding is called surfacing welding. [0003] In the prior art, the material of the spiral blade is made of pure carbon steel or stainless steel, and the method of adding Cr30 movable blade is used, which has general wear resistance, short service life and complicated processing. Contents of the invention [0004] In view of the above technical problems, the purpose of the present invention is to provide a helical blade wear-resistant layer alloy surfacing process with a relatively simple process and prolonging the se...
