Welding:
Before the stainless steel welded pipe is processed and welded, the rust, oil, water, paint, etc. that are harmful to welding should be completely removed, and the welding rod suitable for the steel type should be selected. The processing time of stainless steel welded pipe is shorter than that of carbon steel spot welding, and stainless steel welded pipe brush should be used to remove welding slag. After welding, in order to prevent local corrosion or strength reduction, the surface should be ground or cleaned.
Cutting and stamping of stainless steel welded pipe:
Since stainless steel welded pipes are stronger than ordinary materials, higher pressure is required for stamping and shearing. Only when the gap between the knife and the knife is accurate can there be no poor shearing and work hardening. Use plasma or laser cutting. When gas cutting or arc cutting has to be used, the heat-affected zone should be ground and heat treated as necessary.
Processing and bending of stainless steel welded pipe:
The thin plate can be bent to 180, but in order to reduce the cracks on the curved surface, the stainless steel welded pipe with the same radius and 2 times the plate thickness is given a radius of 2 times the plate thickness when processing along the rolling direction. It is necessary to give a radius of 4 times the thickness of the plate when bending perpendicular to the rolling direction, especially when welding, the surface of the welded area should be ground for cracking in stainless steel welded pipe processing.
Stainless steel welded pipe processing construction and construction attention points
In order to prevent scratches and contamination adhesion during stainless steel welded pipe processing, stainless steel welded pipe construction is carried out in the film-attached state. However, as time goes by, the residue of the paste liquid will be in accordance with the service life of the film. When removing the film after construction, the surface should be cleaned, and special stainless steel welded pipe processing tools should be used. When cleaning public tools with general steel, cleaning should be carried out to prevent iron filings from sticking.
Care should be taken not to allow highly corrosive magnetic and stone luxury cleaning drugs to contact the surface of the stainless steel welded pipe, and the stainless steel welded pipe should be washed immediately when processing. After the construction is completed, use neutral detergent and water to wash the cement, powder ash, etc. attached to the surface
