Rust spots: Stainless steel welded pipe products or equipment may sometimes experience rusting before or during production, indicating severe surface contamination.

The equipment must be derusted before being put into use. Thoroughly cleaned surfaces should be inspected through iron and/or water tests.

Welding spatter: Welding spatter is closely related to the welding process. Argon arc welding (inert gas tungsten electrode welding) has no spatter. However, improper use of welding parameters for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) can result in significant spatter. When this situation occurs, the parameters must be adjusted. To solve the problem of splashing, anti splash agent is applied to each side of the joint before welding to eliminate the adhesion of splashing. After welding, splash proof agents and various splashes are easy to remove without surface damage or minor damage.

Scratches: Mechanical cleaning of scratches and other rough surfaces is necessary to prevent the accumulation of process lubricants or products and/or dirt.

The manufacturing process of stainless steel welded pipes must be precise, and some minor issues can be avoided to ensure product quality.
