Welding Level 4 Study Guide (CDACC Cycle 3) – PDF Ebook

Description

Pass Welding Level 4 with confidence

Welding Level 4: A Practical Study Guide for Kenyan Trainees covers the two new units of the TVET CDACC Welding Level 4 course (Cycle 3, programme 0715 354A) and the 320-hour industrial attachment. It is written in plain English for KCSE leavers and Level 3 holders and illustrated with realistic pictures, accurate diagrams and data charts: MIG inverters and wire feeders, drive rolls and contact tips, TIG torches, tungstens and cups, argon flowmeters, purge set-ups on stainless dairy pipe, heat-tint colours, weld defects and test coupons.

Not sure yet? Download the free sample (43 pages): the front matter, Chapter 1 and the full Chapter 5 on MIG/MAG equipment, wire and setting up.

The Level 3 units (Fabrication Processes I, Arc Welding Processes I, and Gas Welding, Soldering and Brazing) are covered in the companion Welding Level 3 guide.

Who is this book for?

• Level 4 trainees in vocational training centres, technical colleges and polytechnics
• RPL candidates — jua kali and fabrication fundis moving from stick to MIG and TIG who want their skills certified
• Trainers who need ready-made explanations, worked examples, practical tasks and record sheets
• Working welders in body builders, dairy and food-equipment workshops and aluminium fabricators

What’s inside

Part 1: Getting Started, Safety and Science – the Level 4 welder’s job, CBET assessment and where the marks are, arc light and shade numbers, fume from stainless and galvanised steel, argon and CO2 hazards, hot work and waste, CV and CC power sources, duty cycle, shielding gases and cylinders, and the metals you will weld.

Part 2: Metal Inert Gas Welding (Unit 1) – working drawings, cutting lists and operation plans; MIG/MAG machines, feeders, torches and wire; wire feed speed, voltage and transfer modes; plates and pipes up to 10 mm in the flat, horizontal and vertical positions; defects, inspection, finishing and maintenance.

Part 3: Tungsten Inert Gas Welding (Unit 2) – ISO 2553 welding symbols, assembly drawings and the WPS; TIG machines, torches, tungstens and filler rods; DC, AC and pulse; mild steel, stainless with back purge, aluminium and copper alloys; pickling and passivation, inspection and preventive maintenance reports.

Part 4: Attachment, Work and Assessment – the mentoring tool and its critical items, the portfolio of evidence, job cards and quotations, starting a MIG/TIG business, and mock MIG and TIG assessments marked like the CDACC tool.

Reference: a 189-term glossary, a quick reference of welding symbols, process numbers, positions, tungsten colours and typical settings, answers with full working to every practice question, and photocopiable logbook, weld record and maintenance sheets.

Why trainees and trainers like it

• Follows your curriculum: same units, learning outcomes and hours as the official CDACC Cycle 3 Level 4 curriculum.
• Uses the international standards: ISO 4063 process numbers, ISO 6947 positions, ISO 6848 tungsten colours, ISO 2553 welding symbols and ISO 5817 quality levels.
• Safety first: shade selection, fume extraction, argon in tanks and pits, HF and pacemakers, thoriated tungsten dust and pickling acids.
• Real Kenyan costings: wire, gas and power per metre of weld, quotations for a gate and a stainless sink frame, and when a MIG kit pays for itself.
