Description
Technical field
The present invention relates to the inspection field of electronics pipe fitting, and in particular to a kind of detection means of the titanium alloy sub-assembly weld seam of many curved surfaces.
Background technology
In welding structure production, the weldquality obtained from the solder technology that is used at present not yet reaches enough stability, it is thus the quality of guarantee welded unit, it is necessary to quality inspection is carried out to weld seam, it is ensured that weld seam meets the safe handling of the technical requirements and structure of defined.The inspection of weld seam is divided to nondestructive test and the major class of destructive test two.Generally weld seam verifies as nondestructive test aborning, such as visual test, compactness inspection.
The visual test of weld seam has two contents.
First, Weld Profiles inspection：Weld Profiles inspection is that Weld Profiles are detected using survey tool, and it includes that the inspection width of weld seam, the glacing flatness of height and weld seam, the flatness of welding ripple etc. are every and shapes whether index reaches technical requirements；Face of weld quality inspection：Face of weld quality inspection is that with being checked visually or to face of weld with 5~10 times of magnifying glasses, observation face of weld is with the presence or absence of the weld defect such as undercut, overlap, lack of penetration, arc crater and surface pores, slag inclusion, crackle.
2nd, the fine and close inspection of weld seam：The container and pressure vessel of various storage liquid or gas, such as boiler, pipeline component, have certain technical requirements to the compactness of weld seam.To ensure the operation safety of component, it is necessary to carry out seal (tightness)test to weld seam, the conventional weld seam compactness method of inspection has three kinds of the water pressure test, gas pressure test or kerosine test etc.：
1 water pressure test：The water pressure test is applied to the compactness and intensity of inspection weld seam, and its test method has two kinds：A kind of is the seal (tightness)test for open containers, at ambient pressure fills container with water or part is poured water, and additonal pressure, does not check the compactness of weld seam；Another kind is to be filled container with water, and all holes in closed vessel, is improved with the hydraulic pressure in pump handle container and made a strength test, usual test pressure for operating pressure times, and continue for some time at this pressure, then pressure is down to the operating pressure of container, carry out fine and close experiment.With hand hammer away from commissure, gently tapped along bead direction, if finding to there is water droplet or thin water wave to occur on weld seam, illustrate that weld seam is not fine and close.
2 gas pressure tests：Gas pressure test is that compressed air is passed through in closed container, and suds are smeared in face of weld, and when weld seam has penetrability defect, the gas in container will be escaped from these defects, suds is bubbled, referred to herein as where defect.There is a kind of ammonia experiment in gas pressure test, the test method is to being passed through the gas containing 10% ammonia in closed container, a nitric acid mercury 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 test paper there is chemical reaction presentation black splotch in nitric acid mercury solution with ammonia at this, have penetrability defect to show at this.Gas pressure test is generally used for some pipes or the inspection of small-sized pressure-vessel.
3 kerosine tests：Kerosine test be weld seam one side apply spread the whiting aqueous solution, kerosene is applied in the another side of weld seam, if there is the defects such as trickle crackle or penetrable pores in weld seam, kerosene can ooze gap and obvious oil mark is formed on whiting, so that it is determined that weld defect Wei Ge.During experiment, in order to be able to correctly determine the size of defect He Wei Ge, should immediately be observed after kerosene is applied, when there is oil mark, defect area is marked in time, extension oil mark otherwise over time expands, and causes error in judgement to increase.If not finding oil mark point yet by 5min, weld seam compactness is qualified.Kerosine test is used for the seal (tightness)test of non-pressure vessel.With the development of experimental technique, seal (tightness)test can also be carried out using special bleeding agent and developer now, great convenience is brought to test operation.
Current detection device and method are not suitable for the detection of electronics pipe fitting, therefore the weld seam detection of electronics pipe fitting is still detected using prior art, causes the problem that the time is long, efficiency is low.
