What is Roll Planishing?

PURPOSE:

To remove weld build up. Planishing results in a flush smooth weld.

FUNCTION:

Planishing is a quick inexpensive means of removing weld build up and improving surface finish. It is basically similar to a steel mill cold rolling operation only it is limited to the localized area of a weld.

ADVANTAGES:

1. Removes weld build up as much as 20 times faster than grinding and with no cost for consumable abrasive products.
2. Results in an excellent smooth cold rolled surface finish. This is especially important in stainless products requiring a polished surface.
3. Enhances weld metalurgical properties by cold working the "as cast" weld structure.
4. Causes the weld to spread out, often the same amount as the original shrinkage.
