Double V-Butt Joint — Study Resources & PYQs
Preparation of a double V-butt joint using gas or arc welding.
- Estimated study time: 30 minutes
Study resources
- Butt Joint Edge Preparations Explained (YouTube) (Video) — Explains square butt vs single-V vs double-V vs U preparation and, most importantly, WHEN each is used (double-V is for thicker plates welded from both sides to balance distortion).
- SlideShare - Arc Welding Lab Manual (butt joint exercises) (Article) — Use the Single V-Butt exercise as the base and modify for double-V: bevel both faces, weld one side, gouge/clean the root, then weld the reverse side.
- Virtual Labs - Welding Defects (PDF) (PDF) — Double-V joints are usually examined together with distortion and defects (undercut, porosity, slag inclusion, incomplete penetration). This PDF covers them.
- Joints - Single Vee Butt Specification (YouTube) (Video) — Focuses on joint specification terms: root face, root gap, bevel angle, included angle and reinforcement - the labels needed on your sectional sketch.
