Atelier D'Usinage Coté & Audet

What Atelier D'Usinage Coté & Audet does

Atelier D'Usinage Coté & Audet is a Quebec-based contract manufacturer specializing in CNC machining, welding, and mechanical assembly for heavy industrial end-markets, founded in 1989 and headquartered in Sorel-Tracy. The company operates from a 15,000+ square-foot facility and serves customers across hydroelectric, pulp and paper, steel, wind energy, and wood processing. Its equipment fleet includes Mazak, Toshiba, Kuraki, and Okuma CNC machines, with parts-handling capacity up to 10 tons (17,600 lbs), positioning it for large-format infrastructure components rather than high-volume small parts.

The firm is ISO 9001:2015 and ASME certified, qualifying it to produce pressure-bound and quality-critical components for regulated industrial buyers. It supports engineering workflows using FeatureCam, Mazatrol, AutoCAD, and SolidWorks, and offers manual and robotic welding alongside precision large-part machining and assembly. Co-founders Jocelyn Côté and Donald Audet have built the business over more than three decades, and the workforce is disclosed at 11–50 employees.

Revenue is generated through project-based B2B contracts with industrial clients under private ownership. In January 2026, the company secured CAD $4 million in government funding to modernize equipment and expand capacity, while new shareholders Normand Legault, Rénald Boucher, and Philippe Angers joined the cap table alongside the founders, signaling a formal ownership transition aligned with the growth plan.

Core offering

Atelier D'Usinage Côté & Audet operates as a custom large-scale CNC machining and welding shop producing oversized parts and components up to 10 tons for heavy industrial customers. Services span CNC and conventional machining, certified TIG and MIG welding, repair, mechanical assembly, quality inspection, project management, painting, and VpCI long-term storage packaging, delivered on a turnkey basis from quote to final delivery at its 15,000+ sq ft Sorel-Tracy facility.

Product overview

Atelier d'Usinage Côté & Audet (AUCA) is a machining and welding company that operates as a single integrated service provider rather than a modular software platform. The company offers a comprehensive suite of manufacturing services centered on CNC and conventional machining, certified welding (TIG & MIG), repair, quality control/inspection, project management, and specialized packaging. These core services are delivered using the company's extensive equipment fleet (horizontal boring machines, vertical boring machines, CNC machining centers, and CNC/conventional lathes) and supplemented through collaborative partner processing services for secondary operations like heat treatment, surface coating, and specialized cutting. The company serves heavy industries including hydroelectricity, pulp and paper, steel mills, wind energy, and wood processing.
