- Estimated study time: 75 minutes
Study resources
- Bharat Skills style lab blog - Corner Joint by Arc Welding (Article) — Indian ITI/diploma format experiment: MS pieces 100 x 50 x 2.5 mm, electrode size, tools and equipment, numbered procedure and PPE precautions.
- Artizono - How to Weld a Corner Joint: Step-by-Step for Beginners (Article) — Practical tips: use a jig to hold the 90 degree angle, tack first, increase travel speed on thin sheet to avoid burn-through, and keep the bead flowing into both plates.
- Red-D-Arc - Corner Joint Welds: Types, Procedures and Tips (Article) — Distinguishes open corner from closed (flush) corner joints and explains where each is used. Good for the theory question 'types of corner joint'.
- SlideShare - Arc Welding Lab Manual (corner and tee joints) (Article) — Contains the corner joint and tee joint exercises with the standard aim-material-tools-procedure format used in Indian record books.
- Virtual Labs - Electric Arc Welding Process (PDF) (PDF) — Covers arc welding equipment, electrodes and polarity (DCSP vs DCRP) - the background needed before welding a corner joint by arc welding.
- Virtual Labs - Welding: Principles and Classification (PDF) (PDF) — Government Virtual Labs lesson on the principle of welding and the full classification chart of welding processes. Read this before any welding experiment.
- Virtual Labs - Gas Welding / Oxy-Acetylene Welding (PDF) (PDF) — Oxy-acetylene equipment and the three flame types (neutral, oxidising, carburising). Essential for the 'by gas welding' half of every job in this unit.
- NPTEL - Manufacturing Processes: Casting and Joining (Article) — Week 3 onwards covers joining processes, types of joints, weld metallurgy and welding defects. Free IIT lectures with video.
