“Vertical Beam Welding Line” automatic, two or four head submerged arc-welding lines.
These machines are specifically designed for the manufacture of welded “T” and double “T” girder-beams with parallel or converging flange. The beam is fed into the machine and both sides of the beam are welded simultaneously.
When double “T” beams are being manufactured, once the first flange has been welded, the beam is flipped over and fed back into the unit once again.
This machine is capable of welding both symmetrical and non-symmetrical beams without the need for tacking, as well as box-girders (pre-tacked).
