Beam welding lines - Horizontal type


Automatic Welding lines

“Horizontal Beam Welding Line” automatic, two or four head submerged arc-welding lines.

These machines are specifically designed for the manufacture of welded double “T” girder-beams with parallel or converging flange. This machine is particularly effective when the welding bead is one sided. When the beam is processed the two sides are welded simultaneously.


The flanges are loaded in squared position with the web, either manually or automatically. The infeed conveyor moves the three components under the working unit. After the operator inputs the geometric parameters, the machine starts the welding process.

This machine is capable of welding both symmetrical and non-symmetrical beams without the need for tacking, as well as box-girders (pre-tacked).

  • Tacking required only at the top of the profile in order to obtain the proper angle between the web and the flange.
  • 8 times less space required in the workshop, compared to a traditional solution
  • Only 3 operators, 70% less than a traditional solution
  • No overhead cranes required for any intermediate handling
  • Higher productivity. For the twin line up to 300 meters of welded beams in 8 hours
  • Symmetrical welding condition for high quality results
  • Integration of WPS software for full standardization of the welding process
