Professional Aluminum Welding Services in Calgary

We perform TIG welding on a wide range of aluminum components, including radiators, fuel tanks, structural frames, cast housings, marine parts, and custom fabrications. Our services go beyond radiator-only repair. We weld any aluminum part that can benefit from a professional TIG weld, from a cracked valve cover to a fully fabricated aluminum enclosure.

TIG welding, also called GTAW (gas tungsten arc welding), uses a tungsten electrode and argon shielding gas to create precise, high-quality welds. It is the preferred method for aluminum because it gives the welder direct control over heat input, which prevents burn-through on thin materials. TIG also produces clean welds with no spatter, which matters when welding pressurized or visible components.

Aluminum melts at a lower temperature than steel, conducts heat two to three times faster, and forms an oxide layer that melts at a much higher temperature than the base metal. These properties mean a welder must use AC current, argon gas shielding, and precise torch technique to produce a sound weld. Steel welding methods like MIG or stick do not transfer well to aluminum work.

We serve automotive shops, fleet operators, marine businesses, agricultural equipment owners, HVAC contractors, and industrial manufacturers. Any industry that uses aluminum components for weight savings, corrosion resistance, or heat transfer can benefit from professional aluminum weld repair and fabrication, whether you need general welding services, specialized heat exchanger repair, or fuel tank repair in Calgary.

Yes, in most cases. Cracked intake manifolds, transmission cases, compressor housings, and pump bodies can be TIG welded back to full strength. The key is proper cleaning, preheating the casting to reduce thermal stress, and using a filler alloy that matches the base material. Not every crack is repairable, so we inspect each part and give an honest assessment before starting work.
