What is a Stub in Welding?
In welding, a stub is the short length of filler metal electrode, welding rod, or brazing rod that remains after its use for welding or brazing. It is important to remove stubs before starting a new weld or braze joint, as they can cause the arc to wander and create an uneven bead. In addition, stubs can act as a heat sink, cooling the weld pool and making it more difficult to achieve a good weld.
- If you are welding with an electrode or rod that has a stub on it, be sure to remove the stub before starting the next weld or braze joint.
- If you don’t, the arc may wander and create an uneven bead. In addition, the stub can act as a heat sink, cooling the weld pool and making it more difficult to get a good weld.
When you are finished welding or brazing, snip off the stub close to the base of the electrode or rod. If the stub is too short to snip, you can use a pair of pliers to twist it off. Once the stub is removed, you can start your next weld or braze joint.
What is stub-in and stub-on? What is a stub-in branch?
In welding, stub-in (a stub-in branch) is the short length of filler metal electrode, welding rod, or brazing rod that remains after its use for welding or brazing. Stub-on is a similar term used to describe the same thing.
