Full-Service Welding &
Mechanical Support
From pipe welding in mechanical rooms to structural steel on major industrial sites, pipeline welding across Alberta, and mobile rig welding — BoldArc shows up, stays on-site, and gets it done.
Mechanical Pipe Welding
Precision pipe welding for condo and commercial buildings. We work in mechanical rooms, install complete pipe systems, and weld in-position or prefabricated — whatever gets your job done fastest.
Our process-improvement mindset means we look at the whole scope, find prefabrication opportunities, and reduce time spent in awkward positions at height.

Pipeline & Rig Welding
Across Alberta
BoldArc operates as a fully equipped rig welder in Calgary and across Alberta — truck-mounted, generator-powered, and ready to deploy to pipeline, oilfield, and remote industrial sites. F3-F4 and F3-F3 pipeline qualified. We’ve worked with Primoris on major oilfield projects in Fort McMurray.
We weld to API 1104 pipeline procedures and hold CWB and B-Pressure certifications for regulated pressure work. Whether it’s a cross-country tie-in, a wellsite repair, or a gathering line install — we mobilize fast and weld to spec.
