FCB (Flux Copper Backing) Welding Operator & Technician Training

Offered by Pertecnica Engineering

Flux Copper Backing (FCB) Welding is a specialized welding technique used for joining thick steel plates with high-quality, defect-free welds. This process involves placing a copper backing strip with flux behind the joint to support the molten weld pool, prevent burn-through, reduce distortion, and enhance penetration. FCB welding is widely applied in shipbuilding, heavy engineering, pressure vessel fabrication, and structural steel projects.

In modern fabrication industries, FCB welding ensures deep penetration, consistent weld quality, and minimal rework, especially in thick-section welding. Skilled operators and technicians are essential for proper setup, flux handling, and process control. This training program emphasizes hands-on, practical skills for operating and maintaining FCB welding processes effectively.
