📅 Lesson Plan & Schedule
Course Outcomes & Weekly FlowCO1/CO2 and the 14-week schedule
Course Outcomes
- CO1: Conduct appropriate methods, techniques & tools to produce a part according to workshop procedures
- CO2: Perform appropriate techniques/tools to address well-defined engineering problems, aware of limitations
Weekly Flow
- W1–W2: Introduction to Safety & Regulations + Lab tour
- W3–W5: Workshop Session — Welding 1 (SMAW) & Welding 2 (MIG)
- W6–W8: Continuous Assessment — Practical Test & Technical Report
- W9–W11: Workshop Session — Metal Foundry (mould making, melting, pouring, finishing)
- W12–W14: Metal Casting — Sand Testing Preparation & GFN determination
- Study Week → Final Exam as per faculty academic calendar
🧪 Lab Sheets & Procedures
Arc Welding (SMAW)Set up & operate an arc welding station
- Wear approved eye protection, flame-resistant clothing, long sleeves (no cuffs), safety boots & gloves
- Ensure the welding machine is properly earthed and all connections are tight, clean & dry
- Keep flammable materials away from the working area
- Never scratch the arc on top of a gas cylinder; turn off the machine when not in use
Gas Welding (Oxy-Acetylene)Regulator pressures & shutdown order
- Wear welding goggles, leather apron & leather gloves at all times
- Acetylene regulator: 0–1.5 bar · Oxygen regulator: 0–1.0 bar
- Close the oxygen valve at the blowpipe first when shutting down the flame
Foundry — Green Sand MouldingMould-making principles for sand casting
- Materials: silica sand, coal dust, water, bentonite
- Wear suitable PPE before pouring molten metal from the casting ladle
- Pour carefully and quickly; allow the casting to cool before removing the cope
Foundry — Grain Size & GFNGrain Fineness Number determination
- Determine sand grain size and calculate the Grain Fineness Number (GFN)
- Used to assess moulding sand suitability for casting quality
Foundry — Sand Testing (Permeability)AFS Permeability formula
- Standard permeability determined by time for 2000 cm³ of air to pass through the sand specimen
- AFS Permeability formula: P = 3000.7 / T(sec)
📝 Assessment Forms
Lab Assessment FormParts A & B — 80% of total grade
- Part A (40%): material/tooling selection, correct methods, identifying & correcting issues, applicable codes & safety awareness
- Part B (40%): method & procedure, drawing interpretation, machining parameter selection, measuring technique, risk identification
Technical Report TemplatePart C — 20% of total grade
- Introduction & Theory (2) · Material & Method (6) · Result & Discussion (8) · Conclusion (2) · Format (2)
- Must include safety procedures, PPE photos, standard calculations & references
✅ Assessment Rubric
How You're Graded1 (Very Poor) → 5 (Very Good)
Rated against 3 criteria, mapped to CO/PO/DK/DP outcomes:
| Criteria | What's assessed |
|---|---|
| Depth of knowledge required | Correct material/tool selection, reading drawings, applying proper methods |
| Familiarity of issues | Identifying & correcting machining/casting issues, calculations, results |
| Extent of applicable codes | Following relevant codes/standards, safety procedures, PPE awareness |
Part A/B Practical = 40%+40% · Part C Technical Report = 20%
