Is the buildup of a groove weld above the surface of the base material ever removed?

The buildup of a groove weld above the surface of the base material can indeed be removed, which makes the statement true. In many welding applications, after a groove weld is completed, excessive buildup may not serve a functional purpose and can interfere with the intended fit or finish of the welded joint.

Removing this buildup helps achieve a smooth surface and ensures better performance in subsequent processes, such as machining or applying coatings. In some instances, it may also improve the overall appearance of the weld and the finished product. Furthermore, the process of removing excess weld material can also help in the detection of any defects that might be hidden beneath the buildup, ensuring the integrity of the weld.

While the statement about removal being done for aesthetic purposes can hold truth in certain contexts, the removal is primarily conducted for functional and quality assurance purposes. Additionally, if specified in the drawing, it indicates that there may be specific requirements in place for the final profile of the weld, reinforcing the necessity for proper weld preparation and finishing.
