Description
Technical field
The present invention relates to elbow pipe welding technical field, more particularly to a kind of radius of curvature R 1.5D corrosion resistant alloy composite bents
Head tube part preparation method.
Background technology
In the prior art, corrosion resistant alloy composite plate is because of its extremely low phosphorus content (≤0.02%), with higher anticorrosive
Ability and be widely used.But these composites also have in the application of radius of curvature R 1.5D corrosion resistant alloy composite elbow pipe fittings
Certain difficulty, thus most countries use overlaying method to solve corrosion resistant alloy composite elbow pipe fitting inner wall anticorrosion layer.And
For radius of curvature R 1.5D corrosion resistant alloy composite elbow pipe fittings, using traditional heap welding making method, fabrication cycle is long, cost pole
It is high.
The content of the invention
The present invention solves the technical problem of provide a kind of radius of curvature R 1.5D corrosion resistant alloys composite elbow pipe fitting system
Make method, by changing manufacturing process, improve production efficiency.
To solve above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：
A kind of radius of curvature R 1.5D corrosion resistant alloys composite elbow tube manufacture method, it is characterised in that comprise the following steps：
A1. elbow internal diameter size is measured, and the fan-shaped alloy flitch of multiple size identicals is marked off according to surveyed internal diameter size；
A2. the fan-shaped alloy flitch of gained is entered into heating and puts molten condition, recycle stamping machine to carry out drop stamping, until alloy material
Plate is processed to arc semi-circular tube；
A3. the arc semi-circular tube of gained in A2 steps is matched two-by-two, along connection after by two arc semi-circular tube docking
Welded and form a complete elbow semi-finished product in gap；
A4. by the elbow semi-finished product two ends bevel of gained in A3 steps；
A5. gained elbow in A4 steps is surface-treated, surface lacquer processing is carried out after polish burr and cleaning.
Further, basic unit's bottoming is carried out using argon tungsten-arc welding in the A3 steps, recycles Lincoln weld to tap into
Row outward appearance shaping.
Further, fan-shaped alloy material plate is resisto in the A1 steps.
Further, in the A2 steps, flush after two arc semicircle end surfaces, first the short circular arc on the inside of welding, then
Long circular arc on the outside of welding.
Further, gained elbow finished product after A5 steps is identified and packed.
The beneficial effects of the invention are as follows：The situation of prior art is different from, the present invention can be using precisely fan-shaped alloy material
Plate blanking, and drop stamping point valve butt welding technology, effectively reduce the generation of waste material, save financial cost.Meanwhile, relatively
In conventional fabrication method, the present invention can effectively save making duration and cost.
