Pipe Fabrication & Coded Welding in Katherine
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 Katherine and the Northern Territory. Katherine's pastoral, civil and RAAF Tindal operations need durable repairs and fabrication that hold up to hard outback use. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Katherine 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.

Welding & fabrication in Katherine, NT
Katherine sits at the crossroads of the Stuart and Victoria Highways and is anchored by RAAF Base Tindal, now in the middle of a major Defence-funded expansion. Around it sit large pastoral stations, civil contractors and an agricultural sector that all run hard equipment in unforgiving conditions.
We mobilise crews, rigs and machining capacity down the highway for planned fabrication and on-site breakdown repair. Outback dust, heat and heavy use demand durable welds and hardfacing that last — that's what we build to.
