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
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
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.
