Precision fabrication for any industrial job
Humpty Doo Welding and Fabrication delivers general fabrication & 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.
Steel, aluminium or stainless — from a single bracket to a full structural package, we fabricate to drawing and to AS/NZS standards. Profile cutting, rolling, bending, welding and finishing all happen under one roof at our Humpty Doo workshop.
Need it installed? Our mobile crews take the same standards on site. One-off, prototype or full production run — we deliver durable work, on spec and on time.

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.
