Boilermakers and welders build and repair the steel that holds Australia together — bridges, mining equipment, pressure vessels, structural frames, pipelines and heavy machinery. If you like the idea of turning raw metal into something solid and permanent, and you don't mind hard, hands-on work, a boilermaking and welding apprenticeship is a strong, well-paid choice with demand right across the country.
This guide explains what the trade involves, how the training works, what you'll earn, how long it takes and how to get your start in Australia.
What the work involves
Boilermaking (also called metal fabrication or heavy fabrication) is about shaping, joining and assembling steel and other metals. Welding is a core part of it, but so are cutting, forming and reading engineering drawings.
Typical tasks include:
- Reading and interpreting engineering and fabrication drawings
- Cutting metal with oxy, plasma and other tools
- Welding using processes like MIG, TIG, stick (MMAW) and flux-cored
- Fabricating structural steel, frames, tanks and components
- Grinding, fitting and finishing
- Repair and maintenance welding on plant and equipment
- Working to strict safety and quality standards, including weld inspection
You might work in a fabrication workshop, on construction sites, in mines, on infrastructure projects or in ship and rail yards. It's physical, hot work and you'll be in full PPE, but there's real satisfaction in seeing what you've built stay standing for decades.
Qualification and training
Most people train through the Certificate III in Engineering – Fabrication Trade (MEM30319 or its current equivalent), specialising in areas like heavy fabrication, light fabrication or welding.
Your training splits two ways:
- On the job: the bulk of your skills develop in the workshop or on site under a qualified tradesperson.
- Off the job: you attend TAFE or an RTO in blocks or one day a week for theory and practical assessment.
Welding to a professional standard takes practice and formal certification. Some employers and industries require welders to hold specific weld qualifications (for example, to relevant Australian Standards) for pressure or structural work. You'll also need a White Card for construction sites, and you may pick up extra tickets like working at heights or confined space entry.
How long it takes
A boilermaking and welding apprenticeship usually runs around four years full-time. It's formalised through a training contract registered with your state or territory training authority, and it's increasingly competency-based — progress well and you may finish sooner.
There's a probation period at the start. See Apprenticeship Contracts and Probation Explained for how that works.
What you'll get paid
Boilermaker apprentice wages are generally set by the Manufacturing and Associated Industries and Occupations Award. Your pay is a percentage of the qualified rate and steps up each year.
You may also be entitled to:
- A tool allowance
- Overtime, shift and penalty rates (common in this trade)
- Site and travel allowances on some projects
- Superannuation paid on top of your wage
Because wage rates change, use the Wage Calculator for a current estimate and read Allowances and Overtime Explained. The Fair Work Ombudsman is the official source for entitlements. Note that boilermakers working in mining or FIFO roles can earn very well once qualified.
How to get started
Employers value attitude, reliability and a genuine interest in metalwork over top marks. The practical path:
- Step 1: Finish school (Year 10 minimum; Year 12 preferred). Maths and tech/metalwork subjects help.
- Step 2: Consider a pre-apprenticeship or engineering VET course to build basics — see Pre-Apprenticeship Courses: Are They Worth It?.
- Step 3: Get your White Card and, if you can, a driver's licence.
- Step 4: Apply for vacancies. Browse apprenticeship jobs and create a free profile to reach employers.
- Step 5: Prepare for interviews with our interview tips and How to Practise for an Apprenticeship Interview.
Group training organisations are another way in — they employ you and place you with host businesses. See How Group Training Organisations Work.
Skills and traits that help
Strong boilermaking apprentices tend to be:
- Physically fit and comfortable with hot, heavy work
- Steady-handed and patient — good welding takes practice
- Precise, with an eye for reading drawings and hitting tolerances
- Safety-conscious around fumes, heat, sparks and heavy loads
- Reliable and punctual — see Reliability Beats Talent

Where it can lead
Once qualified, you'll have a portable, in-demand trade. Options include:
- Specialising in high-pressure, structural or specialist welding
- Getting weld certifications that command higher pay
- Moving into mining, resources or FIFO work
- Becoming a leading hand or supervisor — see Becoming a Leading Hand
- Moving into welding inspection, supervision or running your own fabrication business
Welding skills are needed everywhere from workshops to the mines, so a qualified boilermaker rarely struggles to find work.
Key takeaways
- Boilermaking and welding is about shaping and joining metal to build and repair structures, machinery and equipment
- You'll complete a Certificate III in Engineering (around four years) split between the workshop/site and TAFE/RTO study
- Formal weld qualifications and site tickets like a White Card boost your employability
- Pay is set by the Manufacturing Award, rises yearly and includes allowances and overtime — check the Wage Calculator
- Get started by finishing school, building basics, getting your tickets and applying for jobs
- It's a well-paid trade with strong demand, especially in mining and resources, and clear paths to specialise or run your own business
