How to Choose the Best Welding & Fabrication in Adelaide
Use this checklist before hiring any welding & fabrication in Adelaide, South Australia.
- 1
Verify their electrical licence is current at your state's electrical safety authority (e.g. Energy Safe Victoria, NSW Fair Trading).
- 2
Confirm they carry public liability insurance of at least $5 million — ask to see the certificate.
- 3
Get 2–3 written quotes for any job over $500. A written quote protects both parties and clarifies the full scope.

Frequently Asked Questions — Welding & Fabrication in Adelaide
How much does mobile welding cost in Australia?
Mobile welders charge $80–$150/hr plus materials and call-out fees ($100–$200 for metropolitan areas). Simple repairs (cracked trailer chassis, gate repair) cost $200–$600. Custom fabrication (handrails, gates, steel structures) is quoted by the project and can range from $500 to $10,000+. Structural welding attracts higher rates due to certification requirements.
What welding processes are used for steel fabrication in Australia?
MIG welding (GMAW) is the most common for general steel fabrication — fast and suitable for a wide range of thicknesses. TIG welding (GTAW) produces the highest-quality, cleanest welds — used for stainless steel, aluminium, and precision work. MMA (stick welding) is used for site work and heavy structural steel. Plasma cutting and laser cutting are used in production fabrication.
Do welders need to be certified in Australia?
Structural welding (for buildings, bridges, pressure vessels) requires certified welders to AS/NZS 2980. Boilermakers and welders working on pressure equipment must hold relevant Australian Pressure Vessel certifications. General fabrication welding doesn't require formal certification, but Trade Certificate III in Engineering (Fabrication) is the standard qualification.
What is powder coating and how does it differ from paint?
Powder coating is an electrostatic process where dry powder is applied to metal and cured in an oven at 180–200°C, creating a hard, seamless finish. It's more durable, thicker, and more uniform than conventional liquid paint — resistant to chipping, scratching, and UV fading. Powder coating costs $100–$400 for a standard gate, including sandblasting preparation.
How do I prevent steel fabrications from rusting in Australia?
Preparation is critical: sandblast or wire brush all scale and rust, apply a zinc-rich primer immediately after cleaning, then apply a quality topcoat (epoxy or polyurethane for harsh environments). Coastal properties within 1km of the ocean should use marine-grade stainless steel or hot-dip galvanizing instead of paint for longevity. Powder coating over properly primed steel offers good protection.
