Abstract
The invention relates to a double-wire powder gas protection overlaying welding torch; a powder pipe is arranged in the center of an insulation torch body; electric arc is ignited between the welding wires of conductive rods on both sides and a work piece, and between the welding wires of conductive nozzles on both sides and the work piece; the powder is kept smooth and fully molten; the overlaying welding efficiency and quality are improved; appropriate powder components can be selected to obtain the required overlaying welding layer components; and consequently, the overlaying welding cost and the energy consumption are lower.
Description
Technical field
The invention belongs to high efficiency accessory in the consumable electrode gas-arc built-up welding.
Technical background
The continuous monofilament powder Gas Shielded rifle that occurred of state foreign minister, but difficult by wire feed and powder channel coaxial arrangement, the fluency of powder feeding and the melting rate of powder are all not ideal enough, promote and have any problem.Domestic in addition protection built-up welding of flux-cored wire gas and the submerged arc overlay welding that generally adopts, the welding wire kind is limited, and these two kinds of overlaying methods are difficult to the problem of avoiding workpiece overheated.
Summary of the invention
Mariages powder Gas Shielded rifle of the present invention; The centre is the passage of powder delivery, and the both sides wire feed can guarantee the conveying that powder is smooth; The electric arc that mariages constitutes guarantees that again powder fully melts; Improved the efficient of built-up welding simultaneously, powder utilizes the fusing of electric arc superfluous heat as packing material, so reduced weld heat input and dilution rate; Particularly the structural constituent of bead-on-plate weld is not limit by the kind of existing welding wire and flux-cored wire, can select the different powder combination according to different needs, and is flexible, and production cost is lower than medicine core Gas Shielded or submerged arc overlay welding.
The present invention compares the advantage that is had with background technology:
1, guarantees the conveying that powder is smooth;
2, guarantee that powder melts fully;
3, reduce heat input and dilution rate, avoid workpiece overheated, help improving the quality of overlay cladding;
4, do not receive present bead welding wire and flux-cored wire kind and become branch to limit, can select the suitable powder composition as required,
Obtain the composition of required overlay cladding;
5, built-up welding cost low than flux-cored wire built-up welding.
