Pipe Fabrication & Coded Welding in Newcastle
Precision pipe welding, pipeline construction and coded welding solutions for industrial and energy-sector applications.
Coded pipe welding you can certify
Humpty Doo Welding and Fabrication delivers pipe fabrication & coded welding across Newcastle and New South Wales. Newcastle's coal terminals, marine fleet and Hunter heavy industry rely on coded welding and structural repair across port and plant. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Newcastle that we are known for Territory-wide.
We deliver coded welding and pressure pipe welding to AS 4041, API 1104 and ASME standards — pipelines, spools, pressure systems and tie-ins. TIG root with MIG or stick fill, in carbon steel, stainless and duplex, by ticketed coded welders.
On site for shutdowns and tie-ins, or in the workshop for spool fabrication, every weld is documented with NDT coordination and full sign-off. Energy, resources and industrial clients trust us with the welds that matter.

Components are fabricated in our Humpty Doo workshop by accredited welders to drawing and code.

Inspect & hand over
Welds are inspected and documented, the site is cleared and the completed work is signed off.
Welding & fabrication in Newcastle, NSW
Newcastle runs one of the world's largest coal export ports alongside the heavy industry of the Hunter, from the harbour coal terminals to manufacturing and marine work. Port plant, conveyors and marine assets here demand coded welding and structural repair around the clock.
We mobilise crews for shutdowns, structural fabrication and breakdown response across port and plant. Coal dust and salt air are both hard on steel — we weld and fabricate to stand up to the lot.
