What is Galling in Welding?

Galling is a condition that can occur between two rubbing surfaces. It happens when high spots or protrusions on one surface become friction welded to the mating surface. This can cause spalling and further deterioration.

Galling can be a serious problem in welding, as it can lead to welding defects and even equipment failure. It is important to be aware of the risk of galling and take steps to prevent it.

How can you prevent galling?

There are several ways to prevent galling in welding:

  1. One is to use a low-friction welding consumable, such as a flux-cored wire.
  2. Another is to use a galling-resistant alloy, such as stainless steel.
  3. Finally, proper welding techniques can also help to prevent galling.

What is the cause of galling?

Galling is caused by friction and welding heat. As two surfaces rub together, they generate heat. This can cause the high spots on one surface to weld to the mating surface.

What is the galling effect?

Galling can cause a number of problems, including welding defects and equipment failure. It can also lead to increased wear and tear on parts.

What are the symptoms of galling?

The symptoms of galling include: spalling, increased wear and tear, welding defects, and equipment failure.

What is galling and seizing?

Galling and seizing are two different conditions that can occur between rubbing surfaces. Seizing is when the two surfaces become fused together, while galling is when high spots on one surface become welded to the mating surface.

Galling resistance chart

The following chart shows the galling resistance of various metals. The higher the number, the more resistant the metal is to galling.
