Ammonia Refrigeration
Welding & Piping
On an ammonia system, a single bad weld isn’t cosmetic — it’s a leak, a safety incident, regulatory exposure, lost product, and downtime. BoldArc is the B-Pressure-certified, hot-work-insured welding sub that ammonia refrigeration and food-processing companies across Alberta trust to get it right the first time.
Why Ammonia Welding Is Different
The Cost of One
Bad Weld
Ammonia is high-pressure, hazardous, and tightly regulated. The welders who can work on it safely and to code are scarce — and that scarcity is exactly the problem refrigeration contractors and plant owners run into.
Leaks & Safety
An ammonia leak is a life-safety and evacuation event. Sound, full-penetration welds on high-pressure piping are not optional.
Regulatory Exposure
Pressure piping is governed by provincial pressure-equipment rules and the AHJ. Bad documentation or failed welds mean failed inspections and delays.
Downtime & Spoilage
When the system is down, product is at risk and production stops. Every hour of a refrigeration outage is expensive.
Certified, Insured,
Inspection-Ready
BoldArc welds and installs ammonia and refrigeration piping for food-processing and industrial facilities across Alberta — with hands-on experience at JBS, Cargill, Sofina Foods, and Harmony Beef. We understand high-pressure piping, material compatibility, and the documentation your inspections demand.
We’re Red Seal Journeyman and ABSA Grade B Pressure certified, fully insured for hot work ($5M commercial general liability through Lloyd’s, burning/welding/cutting covered), and we fit and weld the whole job — so you get one self-sufficient welder-fitter, not a fitter and a welder to coordinate.
