What Tungsten Inert Gas Welding covers

Drafting a working drawing comes first in Tungsten Inert Gas Welding, then setting up, welding and maintaining TIG equipment (Welding Technology Level 6). You interpret and draft work drawings, develop an operation procedure and read welding symbols. TIG welding covers safety standards, housekeeping, equipment and accessories, material preparation, welding parameters, the welding process, positions, joints, weld defects and finishing. The learner welds metals up to 10 mm thick in flat, horizontal and vertical positions. Maintenance covers identifying machines and tools that need attention, preventive maintenance, repair from the manufacturer's manual and a maintenance report.

Careers after Tungsten Inert Gas Welding

TIG (Tungsten Inert Gas) welding is a precision-focused trade that is in demand wherever strong, clean metal joints are needed. Mastering the full cycle - from reading drawings to maintaining the equipment - means you can step into a variety of Kenyan workplaces, earn a reliable salary, or launch your own service.

  • Metal-fabrication workshops in industrial zones of Nairobi and Kiambu - you draft work drawings, interpret welding symbols, develop safe operating procedures, set the correct parameters and produce high-quality frames, tanks, and structural components, earning a skilled-fabricator wage or charging clients per project.
  • Automotive body-repair and customization shops in Mombasa and Nakuru - you assemble TIG machines, prepare thin-sheet steel, perform flat- and vertical-position welds on chassis and body panels, and finish surfaces to showroom standards, earning hourly rates or a share of the repair bill.
  • Ship-building and repair yards along the Kenyan coast - you read marine-grade drawings, set precise welding parameters for stainless-steel and aluminium hull fittings, and carry out preventive maintenance on welding rigs, receiving contracts from shipping companies or the port authority.
  • Oil-and-gas pipeline and equipment maintenance firms in Turkana and Kitui - you develop operation procedures for high-pressure pipe sections, perform TIG welds on critical joints, and document maintenance reports that meet industry standards, earning specialist wages or consultancy fees.
  • Agricultural-machinery manufacturers in Kiambu and Eldoret - you prepare and weld components for tractors, harvesters, and irrigation systems, ensuring durability in harsh field conditions, and you are paid either as a salaried production welder or per-unit for custom orders.
  • Construction companies erecting high-rise steel structures in Nairobi’s CBD - you interpret structural drawings, set up TIG equipment on site, weld column splices in various positions, and conduct housekeeping and safety checks, earning a site-based wage with overtime opportunities.
  • Artisan metal-sculpture studios in Nairobi’s arts districts - you use TIG welding to join intricate aluminium or copper pieces, finish welds to a fine aesthetic, and maintain your own tools, selling finished artworks or taking commissions that pay per piece.
  • County hospital maintenance departments in Kisumu and Nakuru - you repair and maintain medical-equipment frames and support structures, follow strict safety protocols, and produce preventive-maintenance reports that keep equipment running, earning a stable government or contract salary.
  • Self-employed mobile TIG-welding service for custom furniture and décor in residential areas across Kenya - you transport assembled machines, prepare materials on-site, perform precise welds for kitchen hoods, metal tables, and decorative railings, and invoice clients directly, turning your skill set into a flexible income stream.

Your ability to move from drawing board to finished weld, while keeping equipment in top condition, makes you an indispensable asset in Kenya’s growing industrial landscape. Keep sharpening these skills - you’re building a future that can weld together opportunity and success.
