Welding & Fabrication on our platform refers to the end-to-end production of welded steel assemblies—including frames, bases, platforms, and enclosures—using certified processes and documented quality controls. We connect buyers with fabrication shops that perform material cutting, fit-up, and welding in accordance with recognized international standards. Supported materials include carbon steel (Q235B, S235JR, S355J2), weathering steel (Corten A/B), and stainless steel (304, 316), processed via MIG (GMAW) for general fabrication or TIG (GTAW) for high-integrity applications.
| Cutting | Fiber laser (6kW), plasma, waterjet |
| Bending & Forming | CNC press brakes (up to 600T) |
| Welding & Assembly | Robotic + manual MIG/TIG; certified procedures |
| CNC Machining | 3-axis milling, lathe |
| Surface Treatment | Shot blasting (Sa2.5), powder coating, hot-dip galvanizing |
All listed fabricators hold ISO 3834-2 certification and employ welders qualified under ISO 9606-1 or AWS D1.1. Weld seams are visually inspected per ISO 5817 (typically Class B or C), with non-destructive testing (penetrant or ultrasonic) available upon request. Deliverables include welding procedure specifications (WPS), procedure qualification records (PQR), weld maps, mill test reports (MTRs), and final dimensional inspection reports. For projects requiring CE marking in the European Union, compliant suppliers issue EN 1090 EXC2/3 Declarations of Performance, ensuring traceability from raw material to finished assembly.
