Welding defects are issues that can occur during the welding process. These defects can affect the quality and performance of the welded joint. Below are some common welding defects and their descriptions.
Common Welding Defects
- Crater - A crater is a concave depression at the end of the weld pool. It can occur when the welder fails to maintain a steady travel speed.
- Porosity - Porosity is the presence of voids or gas pockets in the weld metal. It happens when there is insufficient protection of the weld pool.
- Inclusions - Inclusions are foreign materials that become part of the weld metal. They can be from the base material, the welding rod, or the atmosphere.
- Undercut - Undercut is a groove or notch on the side of the weld metal. It is caused by insufficient penetration.
