H-Beam Welding Line

PTW

Brief introduction

Horizontal H BEAM welding production line is a new specially designed by WELDARC Company on the base of its many years’ experience of exploring and manufacturing of light and heavy-duty H beam device. To meet the necessity of market, this welding line is special for light H beam.
H BEAM welding production line consists of IN Feed Conveyor to Tack Welder, In feed H beam,
Reducing welding distortion. It is the perfect device for producing large quantity

Main technical feature

1. Adopts horizontal stand welding and singe arc-double wire welding technology, improving welding speed and reducing welding distortion.

2. When assembling, it only needs to spot weld at the range of 200-500mm of the work-piece head (needn’t to spot weld the whole work-piece), after that, go ahead to the next welding. The welding machine can weld these three steels directly and greatly improve the efficiency of assembling.

3. Adopts the welding way of putting the work-piece horizontally (H beam web panel flat and two flange panels upright) and welding the two welding lines at the same time, which reduces H beam distortion.

4. Adopts thin wire welding, reduces distortion by heat. That means reducing flange distortion after welding, which can greatly reduce workload of flange straightening.

5. The transmission conveyor between each steps and chain type turn-over use of traveling crane.

Work principle

The Main machine consists of main machine and front-back transport conveyor. The main machine has two heads, which realizes welding the two welding lines at the same time. Two welding guns are both single arc-double wire welding, and flux automatic feeding and recovery Unit. The main machine is gantry Type structure. work piece is transported from front conveyor to main machine, after welding, transported by back conveyor. In this concepts Machine will be fixed and work piece will Move.
