Boilermakers fabricate, assemble, install, and maintain large steel pressure vessels, boilers, tanks, vats, and structural steel frameworks used in power stations, refineries, mines, and chemical plants. In South Africa, boilermaking is a MERSETA-registered trade that requires a TVET N2 Certificate and a 4-year apprenticeship. With Eskom's power plants, Sasol's refineries, and South Africa's mining sector all requiring ongoing maintenance, boilermakers are in critical demand. A qualified boilermaker with GCC certification is one of the highest-earning artisans in the country.
Boilermakers read fabrication drawings, mark and cut steel plate and sections, weld and bolt structures, use cranes and rigging equipment, test pressure vessels for leaks, conduct planned maintenance shutdowns on plant equipment, and comply with OHSA regulations and ISO pressure vessel standards.
Grade 10 (Std 8) minimum for TVET N2 entry. Mathematics (Level 3+) and Physical Science recommended for blueprint reading and fabrication calculations. TVET N2, N3 Certificates in Engineering Studies (Boilermaking option) required. Mathematical Literacy accepted for N-level entry.

Complete Grade 10 and enrol at a TVET college for N2 and N3 Engineering Studies with a boilermaking specialisation. Focus on engineering drawing, mathematics, and physical science — blueprint reading is central to the trade.
Register as an apprentice with a MERSETA-accredited employer in the energy, petrochemical, or mining sectors (Eskom, Sasol, Transnet, and Anglo American all recruit boilermaking apprentices). The apprenticeship lasts 4 years and combines practical work with N4–N6 theory. MERSETA bursaries cover TVET fees and pay a monthly stipend.
Pass the Government Certificate of Competency (GCC) Boilermaking trade test. Experienced boilermakers progress to structural steel supervisor, plant maintenance coordinator, or welding inspector. GCC holders working at power stations, Sasol, and offshore platforms earn premium salaries. A GCC (Factories) qualification adds a further career step toward engineering status.
