V-groove
The V-groove is a joint preparation with beveled edges creating a V-shaped gap. It allows complete penetration and improves weld strength through optimal material distribution.
Physical-Chemical Mechanism of Action
The V-groove is created by beveling the edges of both workpieces, forming a V-shaped gap between the parts. This gap allows full penetration of the weld and improves joint strength through optimal material distribution.
Metallurgical Relevance & Welding Risks
The V-groove is especially useful for medium plate thicknesses because it allows full penetration and increases joint strength. However, incorrect beveling or too large a gap can lead to uneven material distribution and impair strength.
Workshop Practice & Action Instructions
To create a successful V-groove, the edges of the workpieces must be precisely beveled. The gap should not be too large (about 1-2 mm) and the weld must penetrate uniformly through the entire thickness. Excessive stress during welding can enlarge the gap and impair strength.
