    Description

    Welding nut is the material (same or different) of the workpiece to be welded. It is by heating or pressurizing or both, and with or without filling material, the material of the workpiece can reach the atomic construction and form a permanent connection.


    Stainless steel passivation treatment is a chemical processing step, which is to coat the surface of the metal with a passivation film after pickling, washing and other steps, so that the metal surface will not be corroded due to contact with air. Therefore, stainless steel passivation treatment is a processing method that can prolong the service life of materials. At present, this processing method has been widely used in the production process of metal materials.


    Stainless steel passivation treatment process:

    1. Degreasing and degreasing, if you are sure that there is no oil on the surface of the workpiece, you can omit this step;

    2. Activation, soaking time is 2-5 minutes, if you are sure that there is no rust, welding spot and other impurities on the surface of the workpiece (such as a newly polished workpiece), you can omit this step;

    3. Passivation must go through the process. The soaking time is 30 minutes, the longer the time, the more complete the passivation film;

    4. Neutralization, soaking time is 3 minutes, if the surface shape is simple, there is no gong pattern, no blind holes, this step can be omitted;

    5. To pass pure water, it must go through the process, and the time is 3 minutes.
