Abstract
The invention relates to a method for detecting a steel weld joint with a layer by using ultrasonic waves. The method comprises the following steps of 1, determining an adhesive force of paint and a layer thickness by using a gridding method and a paint film thickness gauge or determining an adhesive force of paint on the surface of a steel weld joint to be detected and a layer thickness by using manners of referring to manufacture original records of a device to be detected, and the like; 2, regulating attenuation, compensation and a port door of an ultrasonic wave detection device through influence of the adhesive force of the paint and the layer thickness to an ultrasonic dB value so as to determine a dB value needing to be compensated; and 3, after determining a compensation value of the device, brushing a coupling agent on the surface of a weld joint to detect the steel weld joint, and judging whether a defect exists on the weld joint or not. Therefore, the method has the following advantages that a layer on the surface of the steel weld joint does not need to be detected, polished and treated, and a verbose procedure of re-making the paint is eliminated; and the method is simple, economic and affordable.
Description
Technical field

Background technology
The method of utilizing at present ultrasonic detecting equipment to be detected the steel weld seam, only limit to the figure layer of steel face of weld is all polished off, and can be detected after face of weld is polished smooth.But some present main equipments (as bridge fabrication machine, door machine) etc., use and will be rechecked in one, two year, adopts traditional method that face of weld figure layer is polished off to be detected, also to again make paint after having detected, not only time-consuming but also require great effort.Therefore the steel weld seam is detected is a kind of economy economical good method again to band coating.
Summary of the invention
The present invention solves the existing technical matters of prior art; Provide a kind of and detected grinding process without the figure layer to the steel face of weld, also saved the loaded down with trivial details operation of again making paint, simple, the economy detection method that material benefit a kind of utilizes ultrasound wave to be detected the steel weld seam of band figure layer again.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of detection method of utilizing ultrasound wave to be detected the steel weld seam of band figure layer, is characterized in that, comprises the following steps:
Step 1: utilize cross-hatching and paint film thickness gauge to measure the adhesion of paint and figure layer thickness or, by consulting the modes such as manufacture raw readings of equipment to be checked, determine adhesion and the figure layer thickness of steel face of weld paint to be checked;
Step 2: the adhesion by paint and figure layer thickness be on the impact of ultrasound wave dB value, and decay, compensation, the ripple door of regulating ultrasonic detecting equipment are determined and needed the dB value compensated;
Step 3: after the offset of equipment is determined, at face of weld, brush couplant, the steel weld seam is detected, judge weld seam and whether have defect.
In above-mentioned a kind of detection method of utilizing ultrasound wave to be detected the steel weld seam of band figure layer, in described step 1, adhesion and the figure layer thickness of steel face of weld paint to be checked can also be determined by the manufacture raw readings of consulting equipment to be checked.
In above-mentioned a kind of detection method of utilizing ultrasound wave to be detected the steel weld seam of band figure layer, the concrete grammar of determining the dB value that needs compensation in described step 2 is: by the compensation key of regulating supersonic reflectoscope, improve and compensate the compensation of carrying out the dB value; Perhaps by the decay key of regulating supersonic reflectoscope, reduce the compensation that the dB value is carried out in decay; Wherein, dB value=A*F+B*T, wherein A, B are scale-up factor, the adhesion of F representative paint, T representative graph layer thickness, the span of A is 0.1～1; The span of B is 0.1～1.
In above-mentioned a kind of detection method of utilizing ultrasound wave to be detected the steel weld seam of band figure layer, in described step 3, whether judge weld seam exists the concrete grammar of defect to be: if appearring in the defectiveness ripple, explanation has defect, and the size that can judge defect according to shape and the size of defect waves.
In above-mentioned a kind of detection method of utilizing ultrasound wave to be detected the steel weld seam of band figure layer, in described step 3, need not carry out grinding process to the figure layer of steel face of weld, directly after face of weld brushes couplant, butt welded seam is detected.
Therefore, the present invention has following advantage: detect grinding process without the figure layer to the steel face of weld, also saved the loaded down with trivial details operation of again making paint, this method is simple, economy material benefit again.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment:
