Question: 1 / 400

What condition describes overlap in a weld profile?

Less than 90 degrees from the plate surface

The condition that describes overlap in a weld profile is indeed defined as occurring when the weld material does not properly fuse with the base material, causing the weld to extend beyond the proper angle relative to the plate surface. When there is overlap, the angle between the weld profiles and the plate surface is less than 90 degrees. This situation indicates an issue in the welding process, as it can create weaknesses in the joint.

Overlap can lead to mechanical and structural problems because it does not create the necessary bonding between the materials. A proper weld should ideally have a clean joint without any excess material that does not contribute to the strength of the weld. Therefore, understanding the relationship between the weld angle and the plate surface is crucial for ensuring the integrity and reliability of the weld.
