What describes the surface closest to the groove edge in a welded joint?

The groove face is the surface that is located closest to the groove edge in a welded joint. This term specifically refers to the area of the base metal that lies adjacent to the groove and is prepared for welding. Understanding the anatomy of a welded joint is essential for interpreting welding prints and ensuring the correct application of welding techniques.

This definition is pivotal because knowing the location and characteristics of the groove face can significantly impact the quality and integrity of the weld. The groove face is where the actual welding process starts, as it is crucial for the fusion between the base metals and the deposited weld metal.

In contrast, the bevel face refers to the angled surface of a weld preparation that allows for effective penetration and fusion during the welding process. The weld bead represents the actual deposited material that results from the welding process, while the joint root is the deepest point of the groove, which is not as close to the surface as the groove face. Understanding these distinctions aids in properly interpreting welding prints and ensuring that joints are executed according to specifications.
