Minimizing Heat Input. Maximizing Structural Precision.

A Process Portfolio Matched to the Job TIG/GTAW: Used for thin, critical, or highly visible welds, delivering low heat input and top-tier aesthetics. Pulsed MIG/GMAW-P: Provides higher productivity on thicker sections while precisely controlling heat input and eliminating spatter. We use argon-rich gas mixes tailored for stainless steel. Robotic & Laser Welding: For high-volume repeatability and large assemblies, our robotic cells ensure consistency. For minimal distortion, our laser welding capabilities provide unparalleled precision. Back-Purging as Standard Practice We seal and purge the root side of welds with argon gas to prevent oxidation (“sugaring”), preserving corrosion resistance inside tanks, pipe spools, and enclosed chambers. Where specified, we verify purge quality with a digital oxygen analyzer to ensure perfection. Correct Filler Metal, Every Time Our AWS-certified welders follow exact procedures: 304L is welded with 308L, 316L with 316L, and dissimilar transitions (e.g., stainless to carbon) with 309L. This is documented and verified, ensuring the final weldment meets or exceeds the corrosion performance of the parent material. Distortion Control by Design Our process begins with precision-cut parts that ensure excellent fit-up. We then employ strategic tacking plans, balanced welding sequences, strict heat-input limits, and robust fixturing to keep components straight and dimensions true through the entire fabrication process.

Mechanical & Chemical Cleaning Post-weld, we use dedicated stainless-only brushes to remove heat tint. For more demanding applications, we perform pickling using a controlled HF/HNO₃ process to remove the chromium-depleted layer, bringing the surface back to its fully alloyed state. Final Passivation to ASTM Standards We perform final passivation in accordance with ASTM A380/A967 standards. We use either nitric or citric acid processes to dissolve any residual free iron and promote a uniform, corrosion-resistant chromium-oxide film. Citric options are available for food-adjacent environments. Upon request, verification tests (water-break, copper-sulfate, or ferroxyl) can be included in your final documentation package.

3D-to-Shop Integration: We program directly from your 3D models, ensuring design intent is maintained from cutting and forming through final inspection. Advanced Inspection: Our Leica AT960 laser tracker enables rapid, high-precision dimensional checks and as-built verification against your model. Comprehensive Quality Records: We can deliver a complete data package, including MTRs, PMI logs, weld maps, passivation certifications, and final inspection reports—organized and delivered with your shipment.

Water & Wastewater: Clarifiers, troughs, baffles, covers, aeration piping, skids, and frames. Power, Energy & Chemical: Ducting, scrubber internals, dampers, support structures, tanks, and chutes. Food & Beverage (Non-Sanitary): Structural frames, conveyors, guards, and enclosures finished for maximum corrosion resistance. Pulp & Paper / Mining: Chutes, hoods, platforms, and washdown-rated equipment.
