    Box Column Gantry Welding Machine Use Twin Arc Wire for Longitudinal Seam of Box Column Productions Bridge construction

    Box Column Gantry Welding Machine Use Twin Arc and Twin Wire SAW Welding Type for Longitudinal Seam of Box Column Productions in the Bridge construction

    Quick Details of Twin Arc Welding Machine

    • Both Gantry type or cantilever type are available;
    • Automatic SAW welding of box-beam after finishing ESW welding;
    • All the arc-guiding motions of this machine are realized by pneumatic and mechanical device;
    • Both sides synchronous driving system is imported A.C. variable frequency control;


    1. Introduction

    It is cantilever type box-beam SAW welding machine. Welding can adopt single wire, twin wire or tri-wire. It fulfills the automatic SAW welding of box-beam after finishing ESW, which has the features of high efficiency, stable and reliable quality, digital display of welding speed and variable frequency adjustable.

    3. Working principle

    This machine is used for box-beam automatic SAW welding. It also can be used for H-beam fillet welding in down hand after changing the arc guiding rack. After completing the box-beam ESW (electro-slag welding), transfer the box-beam to one side of SAW welding machine. And then transfer the beam to another SAW welding machine after completing one seam. The welding arm with submerged arc welding head can move in vertical and horizontal directions to make the welding head aim at the welding seam. On welding arm, there is pneumatic mechanical arc-guiding device to realize the tracing. And the machine can do the automatic SAW welding. There is flux feeding and recovery device for this machine.
    All the arc-guiding motions of this machine are realized by pneumatic and mechanical device. All the pneumatic control elements are imported parts. Both sides synchronous driving system is imported A.C. variable frequency control. Welding arm UP/DOWN and LEFT/RIGHT motions are realized by motorized gear and rack so as to fit different H-beam sizes and avoid that it cannot stop in the middle if using gas cylinder transmission.

    4. Main features

    The standard models of our box-beam SAW welding machines have the following features:

    • The column-type travel unit is the frame of machine, with rigidity and strength calculated carefully.
    • It has advanced and reasonable structure, all the main parts are de-stressed post welding, guaranteeing safe, reliable working and long life.
    • Trolley travel is driven with 2 A.C. motors and reducers via inverter. Fender roller is fit at lateral side of the rail, ensuring smooth and safe running of the trolley.
    • Welding head and SAW welder adopts Lincoln DC1000/AC1200 twin arc twin wire SAW welding power.
    • Flux feeding and recovery machine;
    • All motion parts have lubrication system;
    • Main electric elements are ABB/Siemens brands;
    • Standard color:
