The invention comprises a boiler barrel and a short pipe, wherein, the short pipe is connected with the boiler barrel through welding the fillet weld. The invention is characterized in that oblique probes with different refraction angles are arranged on the excircle surface of the short pipe; ultrasonic wave ejected by the oblique probe is aligned with the fillet weld and the weld cross section of the short pipe; after moving to a certain distance, each probe of the oblique probe ensures that the ultrasonic wave thereof covers the whole fillet weld and the weld cross section of the short pipe; the movable range of each probe of the oblique probe is within the excircle surface of a radial straight pipe of the short pipe; the inner surface of the boiler barrel is provided with a straight probe; the ultrasonic wave ejected by the straight probe is aligned with the fillet weld and the weld cross section of the boiler barrel; and after moving to a certain distance, each probe of the straight probe ensures that the ultrasonic wave of the probe covers the whole fillet weld and the weld cross section of the boiler barrel.

Description

A kind of radial tubes base fillet weld defect detection on ultrasonic basis of short tube
Technical field
The present invention relates to the inspection field that boiler is made, be specially a kind of radial tubes base fillet weld defect detection on ultrasonic basis of short tube.
Background technology
Radially in the base fillet weld UT (Ultrasonic Testing), right at the superpressure boiler drum Φ235 * 55, Φ135 * 35.75, Φ205 * 52.5, Φ300 * 65, Φ130 * 33.25, Φ270 * 65.1, ΦIn the detection of 405 * 85.55 specifications, exist the forging tube wall, thickness is different, detects curved surface and changes greatly, radially straight section short (60mm-120mm) carries out UT100% to fillet weld and detects, and just must keep the displacement (P that pops one's head in
Figure 375286DEST_PATH_IMAGE001
=2.5TK) just can make acoustic beam cover the whole welding line cross section, reach ultrasound wave 100% and detect.
Existing radial tubes base fillet weld short tube defect detection on ultrasonic basis is: by drawing, increase process allowance when the forging blanking by technology, Deng detect qualified after, eliminate by machine work, the requirement of final maintenance design drawing, after adopting this method, its forging waste of material is big, and the secondary processing expense is big, difficulty of processing is big; Caused whole efficiency low, the production cycle is long, cost is high.
Summary of the invention
At the problems referred to above, the invention provides a kind of radial tubes base fillet weld defect detection on ultrasonic basis of short tube, its do not waste forging and do not produce secondary processing cost, whole efficiency height, with short production cycle, cost is low.
A kind of radial tubes base fillet weld defect detection on ultrasonic basis of short tube, its technical scheme is such: it comprises the drum cylindrical shell, short tube, described short tube is welded to connect described drum cylindrical shell by fillet weld, it is characterized in that: the periphery of described short tube is placed with the different angle probe in refraction angle, the ultrasound wave that described angle probe penetrates is aimed at the section of weld joint of described fillet weld and described short tube, guarantee that its ultrasound wave covers the section of weld joint of whole described fillet weld and described short tube after each probe displacement of described angle probe, the scope of the displacement of each probe of described angle probe is all in the periphery of the radially straight section pipe of described short tube, the inside surface of described drum cylindrical shell is equipped with normal probe, the ultrasound wave that described normal probe penetrates is aimed at the section of weld joint of described fillet weld and described drum cylindrical shell, guarantees after the described normal probe displacement that its ultrasound wave covers the section of weld joint of described fillet weld and described drum cylindrical shell.
It is further characterized in that:
The differential seat angle at the refraction angle of the angle probe that described refraction angle is different should be greater than 10% with respect to the angle at a wherein maximum refraction angle;
The probe Qian Yan of the different angle probe in described refraction angle, normal probe ≦ 10 millimeters;
When angle probe can be put into the internal diameter of described short tube, at the inner headed face of described short tube angle probe is set, the ultrasound wave of described angle probe is aimed at the section of weld joint of described fillet weld and described short tube.
After adopting method of the present invention, the flaw detection of the fillet weld of short tube and drum cylindrical shell and the section of weld joint of short tube, guarantee that its ultrasound wave covers the section of weld joint of whole described fillet weld and described short tube after each probe displacement by the different angle probe in refraction angle, feed back its flaw detection information, wherein the displacement scope of each probe is in the periphery of the radially straight section pipe of short tube, so short tube need not to increase process allowance, after also need not to wait detection qualified, eliminate by machine work, the requirement of final maintenance design drawing is not so forging is wasted in this method of detection, and do not produce secondary processing cost, the whole efficiency height, with short production cycle, cost is low.
