Abstract

The invention discloses a cladding device based on argon arc welding, consisting of a cladding spraying gun (4), a coaxial powder conveyer (1), an argon gas source (2) and an argon arc welding machine (3), wherein the cladding spraying gun (4) is connected with the coaxial powder conveyer (1) by a conduit, the argon gas source (2) is respectively connected with the coaxial powder conveyer (1) and the argon arc welding machine (3) by the conduit, the cladding spraying gun (4) is connected with the argon arc welding machine (3) by a current wire and a argon gas conduit. The cladding device based on argon arc welding of the invention has the advantages of simple structure, being convenient to be used, equal heating for every layers of metal powder spraying flow and smooth flowing, and the invention not only takes considerations of arc striking, arc stabling and wolfram pole protection, but also changes the form of the an arc column, to ensure that the electron beam distribution tends to be equalized and decrease the melting of substrate, thus avoiding or releasing the problem of unequal melting depth and effectively increasing the area of a cladding layer.

Description

technical field [0001] The invention relates to a metal powder repairing device, in particular to a cladding device based on argon arc welding for rapid prototyping of small irregular test pieces and repairing damaged and worn parts. Background technique [0002] The traditional powder compaction method in powder metallurgy is mechanical compaction, that is, the powder is filled in the mold, and then the pressure is applied to the piston by a pressure machine, and the powder in the mold is pressed into shape by the extrusion of the piston. This method not only requires special pressure equipment, but also the porosity of the pressed test piece is large, and it is difficult to press and form some irregularly shaped test pieces. [0003] At present, laser cladding molding technology is used in powder cladding technology. This technology combines rapid prototyping technology and laser cladding surface strengthening technology. It not only retains the characteristics of rapid pr...
