Abstract
The present invention relates to the field of non-destructive testing, and in particular relates to a ultrasonic phased array and workpiece geometric fusion display method, comprising the following steps: (1) user-defination of a workpiece geometric model, to be more specific, according to the actual size of a workpiece and the user-defined format, workpiece files are edited; (2) instrument software imaging fusion, to be more specific, instrument software is used for disjunction of the workpiece model files, and the workpiece is displayed in S scan image; (3) position adjustment, to be more specific, by adjusting of S scan and workpiece position, the workpiece position and defects are clearly imaged and displayed on the instrument, and the workpiece edge and the workpiece defects are differentiated and judged. The workpiece defect position, especially the workpiece defects on the corners can be more accurately determined without estimation of the workpiece defects by experience of an operator.
Description
Technical field
The present invention relates to field of non destructive testing, be specifically related to ultrasonic phase array and workpiece Geometrical mergence display packing.
Background technology
At present, China generally uses ultrasonic system for the detection of the defect of product component.Usually, use phased array go flaw detection time, on instrument institute's imaging out only have echo data, the image namely after acoustic reflection.But, inventor finds, in use, there is following technical matters: when only judging defect according to echo, the shape of workpiece can only be estimated by rule of thumb, can omission be produced like this, especially when the defect of workpiece is at its angle, corner, limit, the profile of workpiece when operating personnel are easy to defect to think by mistake, and then generation degree of accuracy is not high and the problem of generation erroneous judgement.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and ultrasonic phase array and workpiece Geometrical mergence display packing are provided.
Object of the present invention is achieved through the following technical solutions:
Provide ultrasonic phase array and workpiece Geometrical mergence display packing, ultrasonic phase array instrument is used to carry out the Non-Destructive Testing of workpiece, it is characterized in that: comprise the following steps: (1) self-defined workpiece geometric model: according to the size of workpiece reality, edit artifact according to user-defined format; (2) instrument software imaging merges: instrument software is extracted part model file, is then shown by workpiece on the image of Sscan; (3) position adjustment: by adjustment Sscan and the position of workpiece, makes the position of workpiece and defect clearly imaging showing on instrument, distinguishes and judge the edge of workpiece and the defect of workpiece.
Preferably, the user-defined format described in step (1) is as follows:
G0 mark drawing starts;
G1 [coordinate points]: transfer point;
G2 [coordinate points]: setting-out;
G3 [coordinate points]: draw arc and be correlated with;
G4 [coordinate points]: draw arc and be correlated with;
G5 [coordinate points]: draw arc and be correlated with;
