For automated submerged arc welding of pipe components, Kjellberg Finsterwalde realized a customized SAW pipe welding plant for inner and outer seams.

Pipe sections with diameters of up to 4,000 mm are welded in longitudinal and circumferential seams.

The submerged arc welding process operates with one or multiple wires with diameters of up to 5 mm, enabling stable and reproducible welding processes even for large component dimensions.

• Movable column and boom on rail system
• Roller blocks with a maximum load of 30 tons
• Automatic, tactile seam tracking for both torches

For the automated production of double-T and cross profiles as well as box girders, Kjellberg Finsterwalde developed a customized SAW double-T beam welding plant.

Welding is carried out in PA and PB positions using the submerged arc double-wire process, with two welding torches operating in parallel.

The system enables high deposition rates, stable welding processes and reproducible weld quality, even for large and heavy components.

• Welding portal for submerged arc double-wire welding
• System and welding control via Siemens PLC with touchscreen
• Travelling welding technology with flux supply and wire depot over a traverse path of approx. 32,000 mm
• Bent parallel wire nozzle bars with separate supports

For the automated joining of plates and rolled sections, Kjellberg Finsterwalde developed a customized SAW double hinged arm welding automat.

The system enables the simultaneous welding of opposing fillet welds on box-shaped profiles with wall thicknesses of up to 30 mm.

The submerged arc welding process ensures high process stability and consistent weld quality in industrial series production.

• Cost-efficient system concept based on the SAW modular system kit
• Base unit welding automat type KA 4-UPDG
