Abstract
The invention aims to provide a method for measuring the weld penetration depth. By the method, the measuring precision of the weld penetration depth can be improved. The method for measuring the weld penetration depth includes A, developing and processing a weld joint, namely, sectioning a welded portion of a welded assembly to acquire a smooth sectioned surface, and corroding the sectioned surface by development solution to obtain developed part displaying the weld joint; B, acquiring an electronic-format image of the weld joint; and C, displaying the electronic-format image in an electronic device by the aid of computer software, drawing a straight line representing the weld penetration depth on the electronic-format image by the computer software, and measuring the length of the straight line by the computer software so as to measure the weld penetration depth.
Description
Technical field
The present invention relates to a kind of dimension measurement method, relate in particular to the welding penetration measuring method.
Background technology
The existing measuring method of welding penetration, it is the end line of measuring weld seam at needs, with the naked eye measure this line by 10 times of magnifieres of normal tape scale (0.2 millimeter/lattice), thereby record welding penetration, and the welding penetration criterion of acceptability is generally at 0.5 millimeter-1.0 millimeters, because the visual inspection unreliability, the statistics error amount is about 30%-50%, therefore easily cause erroneous judgement, product quality and manufacturing cost control are brought hidden danger.
Summary of the invention
The object of the present invention is to provide a kind of welding penetration measuring method, to improve the measuring accuracy of welding penetration.
For realizing the welding penetration measuring method of described purpose, be characterized in may further comprise the steps, A, weld seam video picture are processed, namely dissect the welding position of weldment, and obtain smooth cutting plane, with developing-solution cutting plane is carried out corrosion treatment, to obtain to show the video picture part of weld seam; B, obtain the electronic format image of weld seam; And C, in electronic installation, utilize computer software to show this electronic format image, utilize computer software to draw out the straight line of expression welding penetration at this this electronic format image, and utilize the length of this straight line of computer software measurement, and then record welding penetration.
Described welding penetration measuring method, its further characteristics are in step B, by camera head the video picture part that shows described weld seam to be carried out image acquisition, to obtain the electronic format image of weld seam.
Described welding penetration measuring method, its further characteristics be, in step C, pulls out two parallel lines in a direction, pulls out the described straight line of vertical parallel lines between parallel lines.
Described welding penetration measuring method, its further characteristics are, in steps A, to cutting plane polish, polishing, with nitric acid and alcohol blend cutting plane is carried out corrosion treatment, after the displaying of weld seam, cleaning is also dry, processes to finish the weld seam video picture.
By using measuring method of the present invention, behind image electronic, but enlarged image is determined welding penetration, and the process computer software is measured welding penetration, the reliability of measurement data has had guarantee, thereby objective and correct instruct production scene welding quality control, the simultaneously control of production cost has had the assurance of data, has avoided owing to think that measuring error that factor causes causes the waste of production cost.
Description of drawings
Fig. 1 is the process flow diagram of welding penetration measuring method.
Embodiment
Fig. 1 shows the flow process of welding penetration measuring method of the present invention, can measure a plurality of products in the actual measurement process, and at first butt welded seam is numbered, and gets the weld seam that needs to detect and is numbered, and determines simultaneously to measure the affiliated welding of weld seam assembly product.
As shown in Figure 1, in step 100, extraction needs to measure the weld seam of fusion penetration and dissects with sawtooth, is that polish in the cutting plane surface, polishing with the weld seam end face after dissecing, with nitric acid and alcohol blend, the butt welded seam end face carries out corrosion treatment, after the end face fusion penetration displays, to process with clear water, hair-dryer dries up, namely finish fusion penetration video picture in early stage and processed, obtained the video picture part.
As shown in Figure 1, in step 200, the video picture part is put on the special measurement anchor clamps (with the image scaled that obtains to determine), opened simultaneously the Halogen lamp LED on the anchor clamps, light is all focused on the video picture part, select suitable angle, the prepare image collection; By camera the video picture part is carried out image acquisition, open image acquisition, by adjusting the front, rear, left and right different angles, image acquisition is finished in selection the most clearly image;
As shown in Figure 1, in step 300, the image after gathering is reprinted in the computer image valut; The picture number numbering is consistent with video picture part welding seam No, so that it is corresponding with the measurement weld seam to obtain image data; Choose measurement point at image, according to detecting actual state, pull out two parallel lines in one party makes progress appropriate span, the scope of two parallel lines contains welding penetration, pulls out perpendicular line between parallel lines, and data are revealed after confirming.
