Welding Rotator for Pressure Vessel, Tank, Pipe, Self Aligned type

?

The welding rotator is not only used for welding, but for cleaning. After-rust is light rust-colored surface contamination that appears in a stainless steel weld zone several hours or days after welding. It is the nemesis of shops and contractors that work with stainless steel.

?

The most common source of after-rust is cross contamination. This typically occurs when a grinder with a steel brush is used to clean a stainless steel weld.

However, it can also be caused by cleaning the surface with a stainless steel brush previously used to clean steel. The magnetic characteristic of a stainless steel brush will cause it to collect steel particles, which will be deposited on a stainless steel surface and can result in after-rust.

?

The best way to address this issue is to keep stainless steel brushes in tightly closed containers and to never use them for steel applications.

A third source of after-rust is a metallurgical phenomenon that results from severe cold-working of a surface during cleaning with a brush. If after-rust is encountered and cross contamination can categorically be eliminated as the source of the problem, a potential solution is to switch to a brush with finer wire and use it with light pressure. This will eliminate the deleterious effects of cold-working that can be caused by very aggressive brushing.

By assistance of the welding rotator, the cleaning job become fast and easy.
