Embodiment Construction

[0028] In the following, referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape and structure of each component involved, the mutual position and connection relationship between each part, the function and working principle of each part, etc. will be further described. Details of:

[0029] as attached figure 1 -Attached Figure 9 As shown, the present invention is a method for processing Charpy impact test specimens. The processing steps of the Charpy impact test specimen processing method are as follows: 1) First, remove the Charpy from the test panel approved by the welding process. Specific impact sample blank; 2) Grind and polish one side of the Charpy impact sample blank weld, and then select a corrosive liquid for corrosion according to the Charpy impact sample blank material to form a corrosion surface; 3) respectively in The position of the notch centerline is determined...

Abstract

The invention provides a method for processing a Charpy impact test sample applied in the technical field of dynamic mechanical performance test methods, in which the position of the notch center line is respectively determined on the weld center and the heat-affected zone of the Charpy impact sample embryo; Specific impact sample blanks include single-sided welding or double-sided welding with a cross-section similar to single-sided welding after cutting, and double-sided welding with a cross-section including the root of the weld fusion line, and the root of the weld fusion line is at a distance from the Charpy impact sample. The distance between the upper and lower surfaces is similar, the cross-section is double-sided welding including the root of the weld fusion line, and the distance between the root of the weld fusion line and the upper surface and lower surface of the Charpy impact sample is greatly different. The location of the center line of the notch of the impact specimen, the processing method of the present invention can solve the problem of positioning the notch processing position of the Charpy impact specimen of the material at the weld fusion line in the existing welding process approval Charpy impact test, ensuring that the Charpy impact test Reliable, accurate and reliable test results.

Description

technical field [0001] The invention belongs to the technical field of dynamic mechanical property test methods, and more particularly relates to a processing method of Charpy impact test specimens. Background technique [0002] Charpy impact test is a dynamic mechanics that uses the principle of energy conservation to break the Charpy impact sample of specific shape and size according to relevant standards and break it under impact load to measure the impact energy absorbed during the fracture process. Performance test method. Charpy impact test has become the most widely used traditional mechanical property test for determining the toughness of metal materials due to its simple processing of samples, short test time, and sensitivity of test data to material structure and metallurgical defects. It is one of the important methods for the toughness of materials under impact load, and it is also the most important test method for testing the toughness of materials in the weld...
