Submerged arc welding lines for pipes, I-beams and box sections
Country: Germany · Model: SAW pipe / I-beam / box-section lines
Complete lines for automatic submerged arc welding are built for pipes up to 4000 mm in diameter, I-beams and cruciform beams, and box sections. The pipe line works with one or several wires up to 5 mm, and the beam line has a gantry travel of about 32 000 mm. There is also a separate two-joint machine for box sections based on the KA 4-UPDG.

Description
The pipe line welds longitudinal and circumferential welds both inside and outside. The welding column with a boom travels on a rail track while the workpiece rotates on roller beds with a capacity of up to 30 t, and automatic tactile seam tracking is provided for both torches. The I-beam line produces I-beams, cruciform sections and box girders in positions PA and PB with a twin-wire process. It has a gantry with two parallel torches, control on a Siemens PLC with a touch panel, mobile equipment with flux feed and a wire supply, and curved contact tip rods for parallel wire on separate supports. The two-joint machine welds two opposite fillet welds at once and joins plates and rolled sections into box sections in series production.
How to choose
The line is chosen by the product. For pipes the diameter and mass are decisive, since the roller beds hold up to 30 t and the diameter reaches 4000 mm. For beams the main factor is the length of the product, as the gantry travel is about 32 000 mm. For box sections with a wall thickness up to 30 mm the machine built on a modular kit with the KA 4-UPDG machine is suitable. Separate sources and KA series tractors are purchased when only separate equipment is needed without a line.
