Industrial X-ray flat weld defect positioning method

Abstract

The invention discloses an industrial X-ray flat weld defect positioning method, and relates to the technical field of weld defect detection, and the method comprises the following steps: S1, auxiliary positioning; S2, X-ray detection; and S3, result reviewing. The iron wires are arranged on the upper side and the lower side of the welding seam, so that the defect position can be positioned according to the iron wires after imaging, the rapid positioning effect is achieved, operation is easy, the cost is low, meanwhile, when an X-ray machine is used, the included angle between the X-ray transillumination center line and the welding seam plane can be adjusted, the definition of a defect part after imaging can be improved, the working efficiency can be improved, the defect positioning method brings great convenience to repair of a welding joint of a flat welding seam, and the effect of better practicability is achieved.

Description

Technical field [0001] The present invention relates to weld inspection technique, and in particular as a method of locating defects industrial X-ray flat seam. Background technique [0002] Refers to the flat weld seam angle is 0-5 degrees in the weld, the weld generally detect and locate a way mostly by ultrasonic testing and radiation detection method. [0003] Currently available positioning method, the film formed after the X-ray detector, the weld having been ground smooth, so that there is no reference, so that even if weld defects can be found, but the positioning of the defects is difficult, and prone to error trans where reverse biased, and multiple rework will greatly reduce the mechanical properties of the object, even objects consequences scrapped, and when using an X-ray machine, radiation angle can not be adjusted, so that after the subsequent film forming, may case of defective parts appear fuzzy unclear, resulting in poor usability.

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for locating defects in industrial X-ray flat welds, which has the advantage of setting iron wires on the upper and lower sides of the welds, so that after imaging, the positions of defects can be located based on the iron wires, and the effect of rapid positioning is achieved. , and the operation is simple and low cost. At the same time, when using the X-ray machine, the angle between the X-ray transillumination center line and the weld plane can be adjusted, so that the clarity of the defect after imaging can be improved, which helps to improve work efficiency. This defect positioning method brings great convenience to the repair of flat welded seam welded joints, has better practical effect, and solves the existing positioning method. On the film formed after X-ray inspection, the weld seam is ground due to Smooth, so that there is no reference object, so that even if the weld defect can be found, it is difficult to locate the defect, and it is prone to wrong and reverse deviations, and repeated rework will greatly reduce the mechanical properties of the object, and even cause damage to the object. The consequences of scrapping, and when using the X-ray machine, its irradiation angle cannot be adjusted, so that after the subsequent film imaging, the defect part may be blurred, resulting in poor practicability
