BAIJIAN - Third party testing organization
Before testing、 our testing personnel need to obtain the type of base material and product category (such as castings、 forgings、 rolled parts); The manufacturing or processing status of the inspected object during testing、 including heat treatment status or other conditions; Slope type and size; Surface condition requirements; Welding process specifications or related welding process parameters; Acceptance level; Detection range (including detection requirements for horizontal display); Detection level; Reporting requirements; Necessary information such as corrective procedures after discovering unacceptable displays
The detection frequency should be selected within the range of 2MHz to 5MHz、 and an appropriate frequency should be selected according to the acceptance level requirements. When the attenuation coefficient of the tested object is higher than the average attenuation coefficient of the material、 a detection frequency of around 1MHz can be selected
