General Fabrication & Welding in Darwin
Precision fabrication of steel, aluminium and other metals for bespoke industrial projects, commercial applications and infrastructure.
Precision fabrication for any industrial job
Humpty Doo Welding and Fabrication delivers general fabrication & welding across Darwin and the Northern Territory. Darwin's East Arm wharf, fishing and defence fleets, and major LNG and civil projects demand certified welding and fast on-site response. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Darwin 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.

How we work
Survey & scope
We assess the job on site, take measurements and agree the scope, access and timeline with you.
Fabrication
Components are fabricated in our Humpty Doo workshop by accredited welders to drawing and code.
Mobilise & install
Our crew and fully-equipped rigs deploy to site to install and weld in place.
Inspect & hand over
Welds are inspected and documented, the site is cleared and the completed work is signed off.
Welding & fabrication in Darwin, NT
Darwin is the Territory's industrial and maritime hub, built around East Arm Wharf, the new Darwin Ship Lift marine precinct and the working waterfront at Frances Bay. Add the INPEX and Santos gas supply bases and a permanent Defence presence at HMAS Coonawarra and RAAF Base Darwin, and the city runs on coded welding, structural steel and fast on-water repair.
From our Humpty Doo workshop we're on Darwin sites inside the hour, which makes us a practical call for both scheduled fabrication and breakdowns that can't wait for a barge or a southern supplier. Tropical heat, salt air and big tides are hard on steel up here — we build and repair to handle it.
