Abstract
Description
Technical Field
[0001] The present application relates to the technical field of weld detection, and in particular to a three-phase interface welding detection specimen model. Background Art
[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. In the three-phase interface welding process of metals, the workpiece and the solder melt to form a molten area. After the molten pool cools and solidifies, a connection between the materials is formed. The connection area between the solder and the metal is called a weld. After welding is completed, the weld needs to be inspected to avoid defects such as pores, slag inclusions, incomplete penetration, cracks, pits, etc. These defects affect the normal use of the workpiece. Therefore, weld inspection is an indispensable step.
[0003] In the prior art, when cobalt-based welding materials are used to weld iron-based parent materials, cracks often occur. In order to ensure the quality of welding, it is necessary to use nickel-based welding materials to first weld the iron-based parent material, and the nickel-based welding materials are used as transition layers. Cobalt-based welding materials are welded on the nickel-based materials for filling to achieve the purpose of firm welding; therefore, in the weld area, the iron-based parent material, the nickel-based welding materials and the cobalt-based welding materials form a three-phase interface.
[0004] Phased array detection technology is commonly used to detect the three-phase interface of welds. Phased array detection technology uses electronic control to apply specific focusing laws to multiple chips to achieve sound beam deflection and focusing, and real-time imaging of defects, providing stronger detection capabilities than single probe systems to determine the shape, size and direction of defects. Before phased array detection, it is necessary to use a sample model to calibrate the performance of the instrument, probe and combined system performance. Therefore, the test block is a very important tool in phased array detection. For the three-phase interface of the weld, the transmission speed of the sound wave intensity in three different types of materials is very different. Therefore, during the detection, it is necessary to adjust the parameters of the detection equipment multiple times to achieve the detection of welds of different materials in different areas. At the same time, it is necessary to compare different types of welding defects set on test blocks of different materials multiple times, and the efficiency of welding detection is low.
