Description

A kind of spiral submerged arc steel-pipe welding procedure qualification method
Technical field:
The invention belongs to spiral submerged arc steel-pipe welding Technology field, relate to a kind of spiral submerged welded pipe procedure qualification side Method.
Background technology:
Oil-gas transportation spiral submerged welded pipe is one of domestic and international pipe-line construction major product.According to oil transportation steel pipe Technical specification and technical conditions requirement, before production must on steel pipe or use same alloy system flat board carry out welding procedure Evaluation, to guarantee weldquality.
At present, carrying out qualification of welding procedure on steel pipe needs tubulation factory to carry out pre-manufactured, but due to actual production line relatively Long, completing qualification of welding procedure needs substantial amounts of manpower and materials, and causes the waste of a large amount of tubing in welding parameter regulation process Deng.Use flat board docking carry out qualification of welding procedure, its cannot simulated field welding time tubing real bearing state, welding temperature Field and welding gun locus on spiral seam, the control of its parameter adjustment amount and seam center and actual production exist certain Difference.This is accomplished by one can carry out spiral submerged welded pipe procedure qualification method at laboratory, it is ensured that closely tie with actual production Closing, welding process not only can be adjusted in the space on helix according to welded tube specification with true representations tubing time of day simultaneously Joint welding torch position, eventually through qualification of welding procedure, can optimize welding bead pattern and guarantee weldquality, and can save a large amount of people Power financial resources, reduce the consumption etc. of tubing.
Summary of the invention:
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of spiral submerged welded pipe procedure qualification side Method, overcomes the shortcoming using steel pipe or laboratory to use flat board to carry out qualification of welding procedure on production line.
It is an object of the invention to solve by the following technical programs:
Use the spiral seam pipeline section of about 2 meters, synthesize helix by rotating in a circumferential direction of pipeline section and axial translation, pass through simultaneously Regulation welding gun locus on helix, can complete the procedure qualification of different size spiral submerged welded pipe.Due to this weldering Connect procedure qualification method and simulate tubing stress state in actual production welding process, field of welding temperature and welding gun position completely Putting, the adjustment of its welding parameter is basically identical with actual production line, so its result is in actual serpentine pipe produces, has relatively Good identical property.Welding procedure eventually through evaluation, it can be ensured that the weldquality of the spiral seam tubing of actual production, and A large amount of manpower and materials can be saved, reduce the consumption etc. of tubing.
The technical solution used in the present invention:
Make tubing section circumferentially rotate in a circumferential direction and along tubing section axis direction translate, by rotate in a circumferential direction and axis direction put down Move synthesis spiral motion；Welding gun is made to carry out outside weld in multiple degrees of freedom multi-wire submerged-arc on tubing section spiral line；Use laser with Track system, digital welding power source system, welding parameter Real-time Collection and record system, AC servo drive system, examine in real time Survey and the record welding position of weld seam, welding parameter, groove size and welding bead pattern, it is achieved spiral submerged welded pipe technique is commented Fixed.
Tubing stress state and field of welding temperature and reality when the spiral submerged welded pipe procedure qualification method of the present invention makes welding Border situation is basically identical；Use tubing section circumferentially rotatable and axial translation, it is achieved screw；Multiple degrees of freedom multifibres is used to bury Welding head inside and outside arc, it is achieved welding gun is the adjustment of locus on helix；Use laser tracking system, digital welding power source System, welding parameter Real-time Collection and record system and AC servo drive system, it is achieved soldering joint automatic tracking and welding position Put, detection and the record in real time of welding parameter, groove size and welding bead pattern.
Described spiral seam pipe segment length 2000-2400mm, caliber is Φ 508mm-Φ 1422mmm, and wall thickness is less than or equal to 25.4mm。
Described rotate in a circumferential direction with axial translation refer to pipeline section rotate in a circumferential direction in heating device while with chassis Carrying out translational motion along pipeline section axis direction the most in orbit, it rotates in a circumferential direction speed and axial translation speed depends on spiral Wire bonding speed and the spiral angle of steel pipe.
Described heating device is mainly by steel pipe support rotating roller mechanism, steel pipe anti-channeling hold-down mechanism, welding brush group, platform Car drive mechanism, rotary drive mechanism, anti-channeling compress and drive air cylinder group, brush to drive cylinder composition.Welding process chassis is in-orbit On road while straight line uniform motion, its steel pipe support rotating roller rotates in a circumferential direction.
Described multiple degrees of freedom is that head can move along a straight line in horizontal vertical direction, simultaneously can be at horizontal plane and vertical Rotate, and regulate welding gun can individually regulate welding wire spacing, highly, front and back inclination angle and right position.
Described multi-wire submerged-arc is outside weld mariages, interior weldering 3.
The welding gun helix that is adjusted to of described welding gun locus on helix raises the horizontal anglec of rotation, weldering Rifle roll before and after the anglec of rotation, welding gun with upper-lower position, welding wire before and after inclination angle, distance between weldingwires, dry extension of electrode amount and welding wire exist (outside weld is the deviation outside upper horizontal level of body, and interior weldering is deviation pipe to deviate the distance of steel pipe horizontal level or arc length on helix Internal lower horizontal level).
The present invention has the advantage that and effect:
1, the present invention can use pigtail to replace flat board to carry out qualification of welding procedure weldering at laboratory.
2, the motion mode of welding process pipeline section of the present invention is for rotating in a circumferential direction and axial translation, and it drives and all uses exchange to watch Taking drive system, the screw velocity accuracy of synthesis is high.
3, laser tracking system of the present invention, inverter power sources system, welding parameter Real-time Collection and record system System and AC servo drive system, experimentation can realize soldering joint automatic tracking and welding position, welding parameter, groove ruler Very little, detection and the record in real time of welding bead pattern.
