Advanced Welding & CNC Fabrication Solutions

At FIESCO, we bridge the gap between heavy-duty welding and CNC precision. Our integrated approach ensures that every welded assembly starts with CNC-machined components to guarantee perfect fit-up, reducing internal stress and ensuring the structural integrity of the final product.

Carbol Steel

We provide robust welding solutions for carbon steel, utilizing CNC-prepped joints to ensure deep weld penetration. This process is essential for heavy machinery frames and structural components that require the strength of steel combined with the dimensional accuracy of CNC manufacturing.
