Product Description

Cantilever H Beam Box Beam Automatic Submerged Arc Welding Machine
H-beam box beam production line Professional manufacturer of steel structure box beam gantry welding.

The gantry box beam welding machine has the advantages of simple and reliable structure and reasonable layout.

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

Single arc single wire or double arc double wire TH gantry welding machine can complete the welding of H-beam, cross column and box beam at the same time.

TH-beam welding is equipped with a pair of H-beam arc guide frames and a pair of box-beam arc guide frames. By replacing the arc guide frame, both H-beam workpieces (cross columns) and box-beam workpieces can be welded without removing the workpiece support.

Features:
The H beam Box beam cantilever submerged arc welding machine is T-shaped, the middle door frame is supported and moved, and the welding arms are suspended on both sides.
The H beam or Box beams are placed at a 45º angle on the auxiliary H beam Box beam supports on both sides for boat-shaped welding positions. Both sides can be welded at the same time.
It can also be welded separately on either side.
 

Columns, upper platforms, etc. are made of national standard profiles to avoid excessive plate splicing and welding seams that will cause stress and deformation, ensuring safe and reliable operation of the equipment and long service life.

The traveling mechanism of the Gantry type H beam automatic submerged arc welding machine frame realizes bilateral synchronous drive through frequency conversion control of two AC motors, and stepless speed regulation. The equipped digital display accurately displays the walking speed of the mast.

Pneumatic mechanical tracking device of automatic h beam box beam welding line is used for box beam (column) welding to ensure the relative position of the welding nozzle and the welding seam; through the pneumatic device, the horizontal movement of the arc guide frame and the left and right guide wheels are close to the side of the steel structure.

When the welding seam bends left and right, the arc guide frame is automatically adjusted left and right through the elastic action of the cylinder. The arc guide frame is also equipped with a horizontal plane manual angle adjustment mechanism and a welding torch up and down, left and right, and turning angle mechanisms to further ensure the welding accuracy.

The main operation box is hung below the upper platform and can be slidably moved. The operator stands in front of the operation panel and can move the main operation box according to the size of the welding work piece to observe the welding position of the work piece, thereby facilitating the control of welding
