Single-V butt joint groove
The V-groove is a classic joint preparation with a single bevel on each plate edge, allowing penetration in medium wall thicknesses. The included angle ensures unobstructed access for the filler.
Physical-Chemical Mechanism of Action
The V-groove shape is formed by beveling the plate edges on one side. This creates a rigid, stabilized groove that facilitates the filler metal and also enables full penetration at medium wall thicknesses.
Metallurgical Relevance & Risks When Welding
The correct V-groove shape is crucial for a clean weld. A groove that's too large or too small can lead to porosity, unevenness, and reduced mechanical properties. It's important to bevel the groove accurately and set the included angle correctly.
Workshop Practice & Instructions
Use a protractor or welding gauge to set the groove angle. Make sure the included angle is between 45° and 60°. The plate edges should be clean and smooth to ensure an optimal groove.
