As preferably, the width of the welding bead of heap postwelding is 5mm～10mm, and the thickness of the welding bead of heap postwelding is 2mm～4mm,
The welding bead of heap postwelding is levels helical form against one another.Welding bead thus can be made to be distributed in elbow inner body wall, and
And owing to the internal surface area of the part in the inner part of elbow body is less than the internal surface area of part in the outer part, so arranges and just can make
The state that inside welding bead realization, narrow outside is wide, in practical operation, the width of the welding bead of part in the outer part of elbow body is elbow
1.2 times～2.3 times of the width of the welding bead of part in the inner part of body, so that what welding bead can be the most complete is compounded in
On the whole inwall of elbow body, it is further ensured that quality and the service life of product, enhances the intrinsic intensity of elbow and resistance to
Degree of corrosion.
As preferably, the spiral angle of the welding bead of heap postwelding is 1 °～5 °.Thus can ensure that welding bead is at elbow body
Interior windings, so that this internal densely covered welding bead of elbow, less spiral angle also makes welding bead protect in weld deposit process
Keep steady fixed, further ensure that the welding bead of the part in the inner part of elbow body is narrower than the weldering of the part in the outer part of elbow body
Road.
As preferably, the material that bead welding uses is wlding, and the material of wlding is corrosion-resistant or abrasion-resistant welding wire.
As preferably, the material of wlding is rustless steel or nickel-bass alloy material.
As preferably, the material of elbow body is carbon steel.
The overlaying method of a kind of corrosion-resistant elbow, including spiral built-up welder, comprises the steps:
A, previous step: clean elbow inner body wall, and carry out polishing, polishing；
B, built-up welding: the elbow body after polishing, polishing is carried out spiral overlaid with spiral butt welding machine.
As preferably, the smoothness of the inwall of the elbow body after sanding and polishing is less than Ra 6.2.Control elbow body
The smoothness of inwall just can preferably make welding bead attached thereto, and make weld deposit process more smoothly, thus further
Enhance corrosion-resistant and strengthening effect.
The beneficial effects of the utility model are:
This utility model can make welding bead be distributed in elbow inner body wall, and due to the part in the inner part of elbow body
Internal surface area less than the internal surface area of part in the outer part, so arrange and just can make the wide shape in narrow outside inside welding bead realization
State, so that what welding bead can be the most complete is compounded on the whole inwall of elbow body, is further ensured that the quality of product
And service life, enhance the intrinsic intensity of elbow and corrosion-resistant degree.
