Description

A kind of No clean weld inspection method for bending electron-like pipe fitting multi-point support
Technical field
The present invention relates to the inspection field of electronics pipe fitting, be specifically related to a kind of No clean weld inspection method for bending electron-like pipe fitting multi-point support.
Background technology
In welded structure is produced, the weldquality obtained due to current used solder technology not yet reaches enough stability, thus for ensureing the quality of weld assembly, quality inspection must be carried out by butt welded seam, guaranteeing that weld seam meets the technical requirement of defined and the safe handling of structure.The inspection of weld seam divides nondestructive test and the large class of destructive test two.Usually aborning weld seam verify as nondestructive test, as visual test, compactness inspection etc.
The visual test of weld seam has two contents.
One, Weld Profiles inspection: Weld Profiles inspection adopts survey instrument butt welded seam physical dimension to detect, it comprises every shaping indexs such as checking the flatness of the flatness of the width of weld seam, height and weld seam, welding ripple and whether reaches technical requirement; Face of weld quality inspection: face of weld quality inspection is with visual or check with 5 ~ 10 times of magnifier butt welded seam surfaces, observes face of weld and whether there is the weld defects such as undercut, overlap, lack of penetration, arc crater and surface pores, slag inclusion, crackle.
Two, the densification inspection of weld seam: the container of various storage liquid or gas and pressure vessel, as the component such as boiler, pipeline, the compactness of butt welded seam has certain technical requirement.For guaranteeing the security of operation of component, must carry out seal (tightness)test by butt welded seam, the conventional weld seam compactness method of inspection has the hydraulic testing, gas pressure test or kerosine test etc. three kinds:
1 hydraulic testing: the hydraulic testing is applicable to check the compactness of weld seam and intensity, and its test method has two kinds: a kind of is seal (tightness)test for open containers, to fill container with water at ambient pressure or part is poured water, not additonal pressure, the compactness of inspection weld seam; Another kind is filled by container with water, and on closed container, institute is porose, improves make a strength test with the hydraulic pressure in pump handle container, usual test pressure be working pressure doubly, and continue for some time at this pressure, then Pressure Drop to the working pressure of container, carry out densification test.With hand hammer apart from commissure, knock gently along bead direction, if find, weld seam has water droplet or thin water wave to occur, then illustrate that weld seam is not fine and close.
2 gas pressure tests: gas pressure test passes in closed container by pressurized air, smears suds at face of weld, when weld seam has penetrability defect, the gas in container will be overflowed from these defects, and suds are bubbled, and is defect place herein.The test of a kind of ammonia is also had in gas pressure test, this test method is in closed container, pass into the gas containing 10% ammonia, a mercuric nitrate solution test paper slightly wider than weld seam is sticked in container outer wall commissure, if there is leakage in container welding somewhere, then in this place's test paper, mercuric nitrate solution and ammonia generation chemical reaction present black splotch, have penetrability defect to show this place.Gas pressure test is generally used for some pipes or the inspection of small-sized pressure-vessel.
3 kerosine tests: kerosine test is coated with in the one side of weld seam to spread whiting aqueous solution, kerosene is coated with at the another side of weld seam, if there is the defects such as trickle crackle or penetrable pores in weld seam, kerosene can form obvious oil mark in infiltrate gap on whiting, thus determines weld defect Wei Ge.During test, in order to correctly determine that the size of defect is with Wei Ge, should observe immediately after painting kerosene, when there is oil mark, defect area will be marked in time, otherwise expand along with the prolongation oil mark of time, cause error in judgement to strengthen.If do not find oil mark point yet through 5min, then weld seam compactness is qualified.Kerosine test is used for the seal (tightness)test of non-pressure vessel.With the development of experimental technique, special bleeding agent and developer can also be used now to carry out seal (tightness)test, bring great convenience to test operation.
Current detection device and method are not all suitable for the detection of electronics pipe fitting, and therefore the weld seam detection of electronics pipe fitting still adopts prior art to detect, and cause time length, inefficient problem.
