Description of Horizontal H beam production line:
H beam production line It is the perfect device for producing large quantity of H beam.The production capacity is 1.2-1.5 time than normal production line. It adopts the advanced technology of head assembling, horizontal leveling stand welding, single arc and double wire welding, and realizes fast welding of H beam, reducing welding distortion. It consists of assembling machine, front welding machine, turn-over device, back welding machine and H beam transmission conveyors. The whole line divides into 4 steps, which realizes H beam assembling, saw welding, 180º turn-over device and H beam transmission between each steps.

 

The main feather of the machine in our company is that as follows:
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. The transmission conveyor between each steps and chain type turn-over device reduce the use of traveling crane.
