Abstract
The present invention belongs to a method for arranging probes used for ultrasonic flaw detection of welding seams, particularly to a method for arranging probes used for detecting transversal flaws and oblique flaws in a welding bead during dynamic automatic flaw detection. The present invention is characterized in that two flaw detection angle probes with identical performance parameters are adopted and are symmetrically arranged on both sides of a welding bead, sound beams of the two probes are inclined to the welding bead and intersect in the center of the welding bead, and the two probes are connected in parallel for working in a self-start and self-stop state and are coupled into the same channel of a flaw detector. When the method of arranging probes used for detecting transversal flaws and oblique flaws in the welding bead during ultrasonic flaw detection of welding seams by symmetrically connecting two probes in parallel for work is adopted, in the presence of ensuring flaw detection quality, the number of the probes can be decreased in multiples, the number of channels of the flaw detector can be saved, and the present invention has the advantages of easy and simple operation and little investment.
Description
Technical field
The invention belongs to a kind of probe method for arranging of ultrasonic weld seam flaw detection, detect the probe method for arranging of horizontal and oblique different directions defective in the welding bead during particularly dynamic auto the flaw detection.
Background technology
Number of drawbacks occurs in the welding bead of metal pair welding seam, produce the crackle that produces, volume shape defective is arranged, the line defect of vertical, horizontal and oblique various different directions is also arranged such as lack of penetration, incomplete fusion, pore, when being mingled with various hot melt.During dynamic auto detection longitudinal defect, the acoustic beam of flaw detection angle probe should be perpendicular to welding bead, and probe is in the internal loopback duty; The acoustic beam of flaw detection angle probe should favour welding bead (such as 30 °, 45 ° or 60 °) when detecting oblique defective, and perpendicular to the defective orientation, probe also is operated in local state; And should be at two probes of welding bead both sides symmetric arrangement when detecting transverse defect, the acoustic beam of two probes favours welding bead (such as 30 °, 45 °, 60 °) and intersects at the welding bead center, is in one one receipts state, and required probe quantity is more.When the weldment wall thickness is thin, will adopt 6 probes at least, wherein 2 probes detect longitudinal defect, are arranged in the welding bead both sides respectively, take 2 instrument channel; 2 probes detect transverse defect, are symmetrically arranged in the welding bead both sides, are in one one receipts state, take 1 instrument channel; 2 probes detect oblique defective (such as 45 °), are arranged in the welding bead both sides respectively, take 2 instrument channel.When the weldment wall thickness is thicker (more than 10mm), be the defective of difference detection welding bead upper half part and lower portion, probe quantity also should be multiplied, and promptly needs 12 probes.Under the prerequisite that does not influence the flaw detection quality, manage to reduce probe quantity, thereby alleviate the adjusting and the maintenance workload of probe, can reduce probe bracket and instrument channel number again, have Practical significance.
Summary of the invention
The objective of the invention is for solving the on-line automatic flaw detection of metal pair welding seam, a kind of probe method for arranging that ultrasonic weld seam horizontal and oblique defective is detected a flaw in the welding bead that detects is provided.
A kind of probe method for arranging content Description that is applicable to the ultrasonic weld seam flaw detection that detects interior transverse defect of welding bead and oblique defective of the present invention:
A kind of probe method for arranging that is applicable to the ultrasonic weld seam flaw detection that detects interior transverse defect of welding bead and oblique defective of the present invention, it is characterized in that: adopt two flaw detection angle probes that performance parameter is identical, it is symmetrically arranged in the welding bead both sides, make the acoustic beam of two probes favour welding bead and intersect at the welding bead center, and, two probe parallel runnings insert the same passage of detector device at local state.
Adopt the probe method for arranging of ultrasonic weld seam flaw detection of the present invention, only just can finish detection simultaneously, promptly finish 4 probes commonly used in the past and 3 testings that instrument channel can be finished with two probes and 1 instrument channel to transverse defect and oblique defective with two probes and 1 instrument channel.Under the prerequisite that guarantees the flaw detection quality, probe quantity reduces half, and saves 2 instrument channel again.The weldment wall thickness is thicker, when above, can replace usual method required 8 probes and 6 instrument channel with 4 probes and 2 instrument channel such as 10mm, thereby can reduce by 4 probes and save 4 instrument channel.Detect the probe method for arranging of interior transverse defect of welding bead and oblique defective in the ultrasonic weld seam flaw detection of two probe while parallel runnings of this employing symmetric arrangement, under the prerequisite that guarantees the flaw detection quality, not only can reduce probe quantity at double, but also can save the port number of detector device, advantage easy and simple to handle, that reduce investment outlay is arranged.

Embodiment
The present invention is a kind of to be applicable to that the probe method for arranging of the ultrasonic weld seam flaw detection that detects interior transverse defect of welding bead and oblique defective is to realize like this.Being described further in conjunction with the accompanying drawings, seeing Fig. 1, is the probe method for arranging synoptic diagram of ultrasonic weld seam flaw detection.[I] is the probe socket of 8 passage ultra-sonic defect detectors, and [II] is the butt joint weldment that needs detection, and A is a welded part, and B is a welding bead.1～6 is respectively 1～6 passage of 8 passage ultra-sonic defect detectors, and each passage all has and sends out, receives two probe sockets.Receive and send out short company the electric, promptly 6 passages all are in the internal loopback duty.L
