Grade 10 metalwork Fundamentals of Metalwork – Introduction to Metalwork Notes

1.0 Fundamentals of Metalwork

1.1 Introduction to Metalwork

Metalwork teaches learners how to shape, join and finish metals to make useful objects. It includes practical skills, safety, knowledge of tools and processes, and links to careers and local businesses in Kenya (for example: welding shops, fabrication for gates and roofing, vehicle repair workshops and small-scale manufacturers).

1. (a) Identify and outline the sub-sub-strands:
   • Terms used in Metalwork (glossary)
   • Importance of studying Metalwork as a career
   • Businesses related to Metalwork in the community
   • Importance of Metalwork in day-to-day life
2. (b) Define common terms used in Metalwork as a learning area.
3. (c) Explain the importance of studying Metalwork as a career.
4. (d) Describe businesses related to Metalwork in the community.
5. (e) Appreciate the importance of Metalwork in day-to-day life.

Metalwork

Work that involves cutting, shaping, joining and finishing metals to make tools, structures and products.

Welding

Joining pieces of metal by heating them until they melt together (e.g., arc welding in local workshops).

Fabrication

Cutting, bending and assembling metal parts to make items like gates, frames and shelves.

Forging

Shaping metal by hammering while hot (used for some tools and ornamental work).

Casting

Pouring molten metal into moulds to make parts (common in some factories and foundries).

Sheet metal

Thin flat pieces of metal used to make roofs, boxes and panels. Gauge indicates thickness.

Ferrous and Non‑ferrous

Ferrous metals contain iron (e.g., steel); non‑ferrous do not (e.g., aluminium, copper).

Brazing & Soldering

Joining metals using a filler metal at lower temperatures than welding (used for pipes and electronics).

• Job opportunities: construction, vehicle repair, manufacturing, agricultural implement repair and the Jua Kali sector (small enterprises).
• Practical independence: skills enable you to fix school furniture, bicycles, tools and household items.
• Entrepreneurship: start a small welding or fabrication business (low start-up cost in many Kenyan towns).
• Pathways: apprenticeships, TVET colleges (technical institutes), certificate and diploma courses in welding, fabrication and mechanical engineering.
• Contribution to community development: making gates, water tanks, farm tools and spare parts for local use.

Look around any Kenyan town or trading centre and you will find many metalwork-related businesses. Common examples:

• Welding and fabrication workshops (gates, grills, railings).
• Vehicle and motorcycle repair workshops (boda boda frame repair, exhausts).
• Hardware stores (sell metal fasteners, sheets, tools).
• Roofing and corrugated iron suppliers and installers.
• Small-scale manufacturers (metal furniture, school desks and lockers).
• Scrap metal dealers and recycling centres (collect and sell metal for reuse).
• Industrial machine shops (in larger towns — lathe work, milling).

Example local jobs: welder, fabricator, metal machinist, shop owner, installer, maintenance technician.

• Household items: pots, pans (some), knives, locks and cooking equipment rely on metal parts.
• Infrastructure: gates, window grills, staircases, water tanks and roofing are metal-based.
• Transport: vehicles, motorcycles and bicycles need metal parts and maintenance.
• Agriculture: tools like hoes, plough parts and irrigation fittings are metalcrafted.
• Safety and security: strong gates/locks protect homes and shops.

1. Field visit: Visit a local welding/fabrication shop. Prepare 5 questions (tools used, materials, safety, types of jobs, typical customers).
2. Glossary activity: Make flash-cards (term on one side, meaning and a small sketch/emoji on the other). Use in pairs to quiz one another.
3. Local business map: In groups, walk your trading centre (with permission) and list metalwork businesses. Note services offered and approximate prices for common jobs (e.g., gate fabrication).
4. Small practical task: Under teacher supervision, practice a basic manual task: measuring, marking, cutting thin sheet metal and filing edges to produce a simple bracket. Emphasise PPE (gloves, goggles, apron).
5. Role-play: Simulate starting a small fabrication business: prepare a simple budget, list tools needed and the first three services you will offer.
6. Career talk: Invite a local artisan or TVET instructor to speak about training routes (apprenticeship, TVET), working conditions and safety.
7. Reflective journal: After activities, write a short entry: What did you learn? How could these skills help your family or community?

• Wear safety goggles, gloves and apron. Use hearing protection if noisy.
• Keep long hair tied and avoid loose clothing or jewellery.
• Ensure tools are in good condition and teacher-supervised when using power tools.
• Work in a well-ventilated area (welding fumes are harmful).
• Know where the fire extinguisher and first-aid kit are located.

• Visit a TVET college website or local training centre for sample curricula and further study options.
• Use simple hand tools first; bring in local artisans for demonstrations.
• Adjust practical tasks to available tools and materials; use scrap metal for practice.
• Encourage entrepreneurship: discuss how small investments can grow into community businesses.
