- Estimated study time: 30 minutes
Study resources
- Single V-Butt Joint - Welding Workshop Practice (YouTube) (Video) — Indian workshop demonstration of edge preparation to a 60 degree included angle, root gap, tack welding and running the root and filler runs.
- 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 - Electric Arc Welding Process (PDF) (Article) — Covers arc welding equipment, electrodes and polarity (DCSP vs DCRP) - needed for all four arc welding jobs in this unit.
