In welding terminology, what is the term for the surface that comprises the intersection of the weld face and the base metal?

The term that describes the surface formed at the intersection of the weld face and the base metal is known as the weld face. This area is important because it represents the outer surface of the weld bead, where the weld material meets the underlying base metal. Understanding the weld face is crucial for evaluating the quality of a weld, as it directly impacts factors such as strength and visual appearance.

In welding practices, the weld face can also be examined for indications of defects like undercutting or porosity, which can affect the overall integrity of the welded joint. Mastery of terminologies and their meanings, such as the weld face, is essential for anyone involved in welding, as it ensures proper communication and understanding of welding specifications and standards.

The other options do not specify the correct attribute of the intersection between the weld face and base metal. The base metal interface refers to the area where the base material meets the weld zone, but it doesn't capture the complete essence of the weld face. The throat relates to the depth of the weld but is not the correct term for this surface description. The weld pool refers to the molten metal created during the welding process, not the solidified interface.
