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.

Materials we work with
- Aluminum (6061, 7075, etc.)
- Carbon Steel (A36, 1018, 1045, etc.)
- Alloy Steels (4140, 4340)
- Tool Steels (A2, D2, O1, H13, S7, P20, M2, etc.)
- Stainless Steel (304, 316)
- Brass / Copper
- Engineering Plastics (Delrin/POM, Nylon, UHMW, PTFE/Teflon, PVC, Polyethylene, PMMA, Polycarbonate)
Stainless Steel
Our TIG welding for stainless steel is designed for industries where precision is non-negotiable. By using CNC-machined fixtures, we maintain strict alignment during the welding process, preventing warping and ensuring a surgical-grade finish for medical and food-processing equipment.
