What is not a basic weld joint?

• A. Groove
• B. Butt
• C. Lap
• D. Fillet

Answer: (A)

The main idea here is to distinguish between how parts are arranged (a basic weld joint) and how the edges are prepared for welding (a weld joint preparation). Basic weld joints describe the configuration of the pieces being joined, such as butt and lap. A groove refers to the shape of the cut or notch in the edge that allows weld metal to fill the gap. That makes it a method of edge preparation rather than a joint arrangement itself. Since groove describes how the weld is made in a joint rather than the way the parts are joined, it isn’t classified as a basic weld joint. Butt and lap are clear joint configurations, and fillet is a weld type used on several joint types, but the term groove points to the preparation step, not a basic joint configuration.
