What do you call the total angle formed between the groove faces of two workpieces?

The total angle formed between the groove faces of two workpieces is referred to as the groove angle. This term specifically denotes the measurement taken at the apex of the joint where the two pieces of material meet. Understanding the groove angle is crucial as it influences the welding process, the type of joint being created, and the overall strength and integrity of the weld.

For instance, different groove angles can accommodate various welding methods and filler materials, as well as affect penetration and the heat distribution during welding. Recognizing the correct groove angle is essential for achieving a proper weld and ensuring that it meets the specified design requirements and standards.

Other terms, while relevant in discussions about welding, refer to different concepts. The bevel angle pertains specifically to the angle that a single workpiece is cut at to allow for a joint, while root opening refers to the space between the edges of the joint at the root. The actual throat is a measurement related to the effective depth of a weld, particularly in fillet welding. Each of these terms plays a specific role in welding terminology, but the total angle formed between the faces of two workpieces is distinctly identified as the groove angle.
