Mobile welder in Toronto for on-site construction welding. MIG, TIG, and stick welding for structural steel, repairs, and custom fabrication. CWB certified.
Konstruction Group provides professional on-site welding services across Toronto and the GTA. Our CWB-certified welders specialize in construction welding - beam connections, moment frames, column installations, and structural repairs. We're part of a complete steel supply and install operation: our shop fabricates the steel, and our welders install it on-site. This integrated approach ensures welders who understand every piece they're connecting. We coordinate seamlessly with our framing, insulation, and drywall services. For standalone welding projects, we bring fully-equipped mobile welding trucks to your job site.


On-site welding is our specialty. Our mobile welding trucks are fully equipped with generators, welding machines, grinders, and safety equipment to handle jobs anywhere in the GTA. On-site welding eliminates the cost and delay of transporting heavy steel to a shop. For our supply and install projects, the same CWB-certified welders who do quality work in our shop perform the field connections - ensuring consistent quality from fabrication through installation.
All our welders hold CWB (Canadian Welding Bureau) certification for structural steel welding - required by Ontario Building Code for welding on buildings and structures. CWB certification covers specific welding processes and positions, with documented procedures and quality standards. We maintain certifications, weld logs, and inspection records for your project documentation.
