How to inspect the defects of Qiao Feng brazing tools
⒈Appearance inspection
Appearance inspection is to use the naked eye or a low-power magnifying glass to check the surface quality of the brazing joint, such as whether the solder fills the gap and the exposed end of the solder seam. Whether rounded corners are formed, whether the rounded corners are uniform, whether the surface is smooth, whether there are cracks, pores and other external defects.
Surface defect inspection
Surface defect inspection methods include fluorescence inspection, coloring inspection and magnetic particle inspection. They are used to check the appearance and inspect the surface defects of the brazing joint that cannot be found visually, such as cracks and pores. Fluorescence inspection is generally used for inspection of small workpieces, while large workpieces are inspected by coloring. Magnetic particle inspection is only used for magnetic metals.
⒊Internal defect inspection
Ultrasonic inspection and compactness inspection are mainly used.
Ray ray inspection is divided into rays and rays according to the type of source. It is a common method to inspect the internal defects of important workpieces. It can show the pores and slag inclusions in the brazing seam that are not penetrated, as well as the cracking of the brazing seam and the base material. The range of defects that can be found by ultrasonic inspection is the same. Commonly used methods for testing the tightness of brazed structures include general water pressure test, air tightness test, gas permeability test, kerosene leakage test and mass spectrometry test. The water pressure test is used for high-pressure vessels, the air tightness test and gas permeability test are used for low-pressure vessels, and the kerosene permeability test is used for unpressurized vessels and the mass spectrometry test is used for vacuum sealing joints.
