Mine Maintenance in Mount Isa
Structural repairs, component upgrades and hardfacing for excavators, loaders, crushers and heavy mining equipment.
Keeping heavy mining gear in the cut
Humpty Doo Welding and Fabrication delivers mine maintenance across Mount Isa and Queensland. Mount Isa's underground mines and smelters need hardfacing, machining and structural maintenance that keeps production running. We mobilise from our Humpty Doo base with fully-equipped rigs, bringing the same coded welding and fabrication standards to Mount Isa that we are known for Territory-wide.
Breakdowns don't keep business hours. Our mine maintenance crews deliver structural repairs, hardfacing and component upgrades for excavators, loaders, crushers, conveyors and haul fleets — on site, around the clock, wherever the work is.

Welding & fabrication in Mount Isa, QLD
Mount Isa is north-west Queensland's mining city, built on copper, zinc, lead and silver mines and the smelters that process them. Underground and surface operations here run heavy plant that lives or dies on its wear components and structural integrity.
We mobilise machining, hardfacing and structural-repair capacity to the Isa for planned maintenance and breakdowns. Keeping production moving means components built to spec and repairs that hold under constant load.
