Double-Bevel Joint Configuration
DV weld is a symmetric V-groove with double-sided bevel, reducing distortion and allowing even stress distribution.
Physicochemical Mechanism of Action
The DV weld geometry prevents asymmetric stresses through a symmetric layer sequence. This leads to uniform distortion and improved mechanical stability of the weld.
Metallurgical Relevance & Welding Risks
Asymmetric stress distribution can lead to cracks and hot cracks. The DV weld avoids these issues through its symmetric design, increasing the weld's service life.
Workshop Practice & Instructions
When making a DV weld, use a symmetric layer sequence and watch for uniform distortion. Temperature control during welding is essential to regulate stress distribution.
