A family company with a well-earned reputation for doing a great job at a good price is branching out after winning two lucrative defence sub-contracts.

Humpty Doo Welding and Fabrication started out as a one-man business six years ago – but now employs 15 tradespeople, including three Indigenous Territorians.

Owner Adam Marsh is concentrating on work in the mining, oil and gas, construction, civil and defence industries.

“Our track record proves that we can safely complete a project to the highest standard,” he says. “We’re honest and fair with our clients, offering a reliable, professional and comprehensive service to a constantly changing environment.

“We get the job done right, on time and on budget.”

Humpty Doo Welding and Fabrication, which is CAL accredited and part of the Territory Proud employment and procurement program, provides repair, maintenance, remedial and construction to commercial and domestic industries.

Finishing off two defence subcontracts at Darwin’s Naval facility accelerated the company’s growth.

The business also does a lot of local community work – ranging from schools and colleges to council-owned facilities and sporting venues.

It also engages trainees, apprentices and work experience students to create stepping stones for future education.

The company has successfully carried out major work at mine sites, remote communities, and Darwin’s shipyard, including below waterline plate work.

But the team of highly skilled welders still manages to fit in the little jobs, such as work for local families and small businesses.

“Diverse engineering is what we do best,” says Adam.

The company, which has a fully equipped workshop with yard and laydown area, specialises in mild steel, aluminium, stainless steel, and exotic alloy welding processes.

Expertise includes onsite and offsite work, engineering solutions, field service, mining equipment, fixed and mobile plant, heavy structural, piping, conveyor systems, tanks/pressure vessels, commercial marine refits, including shell and hull plate replacement on ships, work boats, and barges, wharf construction and installations, subsea spool fabrication, farming and agriculture.

Humpty Doo Welding and Fabrication’s capabilities are: CNC plasma cutter; 4.5-tonne forklift; 135 tonne punch and shear; 60-tonne press break; 600mm bandsaw; three mobile field services units; Franna crane; hire equipment (mine spec); one hectare laydown yard; engineering workshop; machining/turning/drilling; and guillotine

Adam and nearly all his staff live in the rural area and are deeply involved in the local community.

The company sponsors and carries out charity work for the local school and childcare centre and donates to local sports clubs.
