About BoldArc Contractors

Built by Welders.
Focused on Performance.

We’re not a management company that oversees welders. We are the welders — on-site, working, solving problems, and keeping your project on schedule.

The Crew

Strategy meets execution. BoldArc combines systems thinking with high-output welding to deliver results that most crews can’t match. When you hire BoldArc, you get certified tradespeople who are invested in your timeline — not just their hours.

For shutdowns and larger scopes, we scale up with a full multi-trade crew — welders, pipe fitters, plumbers, and helpers. 3 welding units on trucks, a generator fleet, and a network of subcontractor rig welders ready to mobilize across Alberta.
