Sheet Metal Galling

Galling is a common problem in sheet metal forming bearings and pistons in engines hydraulic cylinders air motors and many other industrial operations.

Sheet metal galling.

This can result in the metal separating from the component it was originally attached to. Here are some general tips for preventing galling from taking place during any metal project including those with higher galling risks. Studies have shown that acoustic emissions sensors can be used to measure galling. Galling begins at tool defects such as notches or scratches and eventually develops into hard protrusions on the tool surface.

Sheet metal stamping is one of many processes prone to galling a form of wear. Galling is a type of wear that can cause a metal to unintentionally adhere to another metal that it is in contact with. In some cases it will be microscopic while it may damage some metals in these cases it often will not eliminate their usefulness entirely especially if the operation involved has loose tolerances. Limit the amount of friction involved in any application through proper use of lubricant.

Galling occurs when metals with dissimilar hardness the die and the sheet metal come in contact at high speeds and pressures.
