Description
Technical field
The present invention relates to the ultrasonic phase array detection range, more specifically relate to a kind of TKY tubular joint weld ultrasonic phase array detection system.
Background technology
In recent years, deepening continuously and develop along with marine resources development, world many countries is newly-built many marine resources development facilities, wherein mainly contain fixed offshore platform, marine mobile platform and subsea pipeline etc., attack and the corrosion of ocean by soaking of ocean storm owing to often being subjected to for these offshore structures, is prone to crackle at its tubular joint weld place, thereby jeopardizes the safety of national wealth and personnel's life, thereby the Non-Destructive Testing work of offshore platform structure is significant.Offshore platform structure generally is made of various steel jackets, and its pipe node can be divided into three kinds of T, K, Y according to the difference of its structural form.
Existing tubular joint weld ultrasonic testing system, generally the girth joint at long-distance transport pipes detects, and this weld seam is rotational symmetric, when adopting angle probe to detect, only need along the circumferential direction do the detection that one dimension mechanical scanning can be finished butt welded seam.Wherein the most representative, the PipeWIZARD phased array ultrasonic detection system that Canadian R/D Tech company produces is exactly the checkout equipment that is exclusively used in the long-distance transport pipes girth joint.This system is made up of data acquisition unit, pulse generation unit, electric-motor drive unit, phased array probe, industrial computer and display etc.System moves Pipe WIZARD function software under Windows NT interface, finish the linear scanning of butt welded seam, demonstration in real time and result and pass judgment on.This type systematic generally requires wave beam vertical weld length direction when carrying out Ultrasonic Detection, like this, the defect reflection signal of commissure could receive exactly.And for the TKY tubular joint weld, the groove direction and the weld seam of its diverse location constantly change with respect to generatrix direction, and the existing ultrasonic automatic checkout system of commercial tubular joint weld is because all detection needs at girth joint, the central axis of its sound beam direction and measured tube is in same plane, almost can not scan detection to the TKY tubular joint weld.Detect main X-ray examination method or the manual supersonic testing method of adopting at the TKY tubular joint weld at present, still needleless detects the automatic ultrasonic detection system that needs to the TKY tubular joint weld.
Radiological survey X is the important Dynamic Non-Destruction Measurement that weld inspection is extensively adopted, and it is that a kind of X ray that utilizes produces the method that image is checked the metal inside micromechanism to penetrating of metal.As everyone knows, all material all absorbs certain radiation energy, different materials, and owing to density, thickness, different with atomic weight, the absorption difference of its radiation energy, thereby its intensity in transmission is also different.Therefore ray can be used to detect effectively weld seam inherent vice such as pore, sand holes, undercut, lack of penetration, crackle, nonmetal inclusion, burn etc., and weld seam inherent vice image can be observed on video screen or film.It is fast that ray detection has speed, low cost and other advantages, but its image definition is poor, brings difficulty to analyzing defect.For thicker workpiece, also there are problems such as ray can not penetrate.In addition, because ray is harmful, must take effective safety precautions.
In the Ultrasonic Detection of TKY tubular joint weld, because the wall thickness of arm is less, the primary reflection sound path is shorter, and weld defect has more present root and arm side corresponding circle of sensation position in addition, so detect in the arm side usually, the supersonic detection method of TKY tubular joint weld commonly used is manual detection at present.The ultrasonic manual detection of TKY tubular joint weld, because testing result depends on testing staff's experience and technology, the phenomenon that is prone to erroneous judgement and fails to judge, position to each defective place, what need all that the long time carries out the cross section gets shape, mapping and location survey, workload is bigger, all has problems from repeatability and reliability.And for the space three-dimensional curved-surface structure of this complexity of TKY tubular joint weld, manually Ultrasonic Detection can not realize the visual and real time record of testing result.
