Welding Technology · Level 6  ·  5 Chapters

▣ What this unit covers

In this unit, you will be able to confidently perform MIG and FCAW welding on metals up to 16 mm thick, expertly setting up equipment and interpreting working drawings to meet precise job requirements. You will develop the skills to inspect and finish welded products with care, maintain a safe and organized workspace, and uphold strict health and safety standards. By the end, you’ll be ready to tackle real-world welding tasks with accuracy, professionalism, and pride in your craftsmanship.

■ Where this takes you

Working with MIG and FCAW welding opens doors to many hands-on jobs across Kenya’s growing industrial landscape. Whether you join a team or start your own shop, the skills you master here let you turn metal sheets into strong structures that keep our roads, farms, ports and homes moving forward.

  • Metal-fabrication workshops in Nairobi’s Industrial Area - you set up the welding machines, read the shop drawings, and produce frames for gates, shelving and agricultural sheds, earning a steady wage or charging clients per project.
  • Road-construction sites in Kisumu and Nakuru - you perform MIG welds on steel reinforcement and bridge components, inspect each joint for quality, and receive daily site allowances or contract fees for completing critical load-bearing work.
  • Agricultural-equipment repair centres in Nakuru County - you repair and fabricate tractor hitches, irrigation pipe supports and grain-store structures, charging farmers for on-the-spot service and building a reputation for reliable field-ready welds.
  • Ship-repair yards on the Mombasa coast - you use FCAW to join thick hull plates and deck fittings, follow strict marine drawings, and earn higher pay rates from vessel owners who need fast, watertight repairs.
  • Oil-pipeline and gas-distribution projects in Turkana and Kitui - you set precise FCAW parameters for pipe spools, carry out rigorous weld inspections, and receive contractor fees for work that meets demanding safety standards.
  • Solar-panel frame manufacturers in Eldoret and Kericho - you fabricate aluminium and steel frames, finish welds to a smooth surface, and sell completed modules to renewable-energy installers on a per-unit basis.
  • County water-supply projects in Kisii and Machakos - you assemble and weld steel water tanks and distribution rigs, follow health-and-safety protocols on site, and are paid either as a salaried welder or through lump-sum contracts for completed tanks.
  • Mining-equipment maintenance shops in Kitale and Kakamega - you repair heavy-duty crushers and conveyor rollers, inspect weld integrity under harsh conditions, and earn overtime premiums for keeping the mines running.
  • Mobile welding service for informal construction in peri-urban towns - you travel with a compact MIG/FCAW kit, read simple sketches from local builders, finish welds on staircases, railings and small structures, and charge a daily rate plus material markup.
  • Artisan metal-craft studios in Lamu and Thika - you apply precise MIG techniques to create decorative gates, sculptures and furniture, finish surfaces for a premium look, and sell pieces directly to tourists and interior-design clients.

Mastering these skills means you can move confidently between well-paid salaried roles and your own thriving welding business, all while keeping workplaces safe and projects on schedule. Your expertise will be the backbone of Kenya’s infrastructure - keep welding, keep building!
