LASER WELDING
High-Precision Industrial Laser Welding Services
In advanced manufacturing, selecting the correct joining process directly impacts dimensional accuracy, long-term performance, and production efficiency. Graphie provides industrial fiber laser welding services as a strategic complement to traditional arc welding processes.
Located in La Pocatière, Quebec, and serving manufacturers across Canada and the United States, we support North American OEMs seeking a reliable nearshoring alternative for high-precision welded assemblies. Laser welding is deployed where speed, minimal thermal impact, repeatability, and aesthetic quality are critical success factors.
As a vertically integrated manufacturing partner, Graphie guides customers in selecting the most appropriate welding technology. While our CWB-certified TIG & MIG welding services remain the industry standard for many assemblies, from transportation structures to industrial cabinets, laser welding provides a specialized, automated solution for applications requiring low distortion and consistent results at scale.
Fiber Laser Welding:
Precision and Thermal Control
For precision sheet metal assemblies in sectors such as electronics, transportation, and energy systems, heat management is a primary engineering concern. Fiber laser welding addresses this challenge through extremely high energy density and controlled penetration.
By focusing a high-power laser beam on a microscopic spot size, we achieve deep, narrow welds with significantly lower total heat input compared to conventional arc welding.
-
Minimal Heat Affected Zone (HAZ): Rapid energy delivery and fast cooling dramatically reduce thermal stress. This prevents warping, buckling, or panel distortion, particularly on thin aluminum or large flat enclosures.
-
Hermetic Welding Capability: The stability of the fiber laser beam enables continuous, non-porous seams. This makes laser welding ideal for sealed housings requiring strict ingress protection (IP ratings) against dust and moisture, commonly found in vehicle electronics, outdoor equipment, and control systems.
Aesthetic Superiority and
Production Efficiency
Beyond structural performance, laser welding offers clear advantages where visual quality and downstream efficiency matter.
The “Invisible” Joint
Laser welding produces a narrow, uniform seam that is often flush with the parent material.
-
Reduced Secondary Finishing: In many cases, welded parts exit the cell with a clean, visually acceptable joint, eliminating aggressive grinding or sanding and preserving base material thickness.
-
Direct-to-Paint Workflow: Components can frequently move directly from laser welding to our powder coating line. Smooth, consistent seams prevent weld “telegraphing” through painted finishes, an important advantage for high-visibility industrial panels and enclosures.
Strategic Integration with Laser Cutting and Industrialization
At Graphie, laser welding is fully integrated into a controlled manufacturing ecosystem. High-quality laser welds require near-zero joint gaps and precise part alignment. Our upstream fiber laser cutting services, with positioning tolerances of ± 0.001", ensure exact fit-up before welding even begins.
This tight integration between cutting, fixturing, and welding enables the production of recurring series of complex assemblies with exceptional repeatability. For OEMs, this translates into predictable quality, reduced variation between batches, and a more secure supply chain - whether producing pilot runs or stable monthly volumes.
