H Beam Gantry Welding Machine

H Beam Gantry Welding Machine is developed by our company based on the particularity of H-shaped steel boat welding and combined with years of technical experience in the development of I-beam welding equipment. 

It is mainly composed of gantry, sliding plate mechanism, welding torch mechanical tracking device, welding machine recovery processing system, and pneumatic System, electrical control system and submerged arc welding machine.

Features of machine:

  1. 1. LH series H Beam Gantry Welding Machine is equipped with a pair of H-shaped steel arc guide frame and a pair of box-shaped beam guide arc frame. 

By replacing the arc guide frame, both H-shaped steel work-pieces (cross columns) and box beam work-pieces can be welded without removing the work-piece support.

2.Columns and platforms are made of national standard profiles to avoid stress and deformation caused by excessive plate splicing and welding, and to ensure safe and reliable operation of the equipment and long service life.

3.Weld tracking adopts mechanical three-axis tracking;

The arc guide frame 360-degree rotation and floating movement can effectively track the welding seam in real time and reduce the labor intensity of the operator.

The H-shaped steel arc guide mechanism can be welded back and forth, saving return time.
