In the steel welding process qualification test, the content of this test will be described in detail from the following perspectives.
1. Metal detection:
In order to guarantee the quality of welded joints, advanced metal detection technology is used to test the material composition and physical properties of the steel. Through the chemical composition analysis, microstructure observation and mechanical property testing of metal materials, the key performance indicators such as strength, toughness and weather resistance of welded joints can be accurately evaluated.
2. Mechanical property test:
Mechanical properties are one of the important indicators to evaluate the quality of steel welded joints. The laboratory is equipped with advanced mechanical property testing equipment, such as universal material testing machine and impact testing machine, which can test the mechanical properties of welded joints under different loading modes such as tensile, compression, bending and impact. By analyzing the test results, you can evaluate key performance parameters such as strength, stiffness, fatigue life, and fracture toughness of welded joints and help you optimize your welding process.
3. Process qualification test:
The steel welding process qualification test is a standardized process to evaluate the quality of welded joints. According to the requirements of relevant standards and regulations, process qualification tests are carried out for different welding methods and welding processes. By simulating the welding process under actual process conditions in the laboratory, and after metal detection and mechanical property testing of the weld, the quality level of the welded joint can be evaluated and the required process parameters and process instructions can be provided.
