Pipe Fabrication & Coded Welding in Gladstone
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 Gladstone and Queensland. Gladstone's LNG, alumina and port infrastructure calls for coded pipe welding and heavy structural fabrication to tight shutdown windows. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Gladstone 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.

Welds are inspected and documented, the site is cleared and the completed work is signed off.
Welding & fabrication in Gladstone, QLD
Gladstone is one of Australia's busiest industrial ports, ringed by the Curtis Island LNG trains, alumina refineries and aluminium smelting. Coded pipe, pressure systems and heavy structural steel are core to keeping this plant running.
We bring coded welders and fabrication crews in for shutdowns and tie-ins to tight windows, with full NDT coordination and sign-off. When a shutdown clock is running, documented welds delivered on schedule are everything.
