PTW (H-Beam Welding Line)
Brief introduction
- Horizontal H BEAM welding product line is a new specially designed by WELDARC Company on the base of its numerous years expertise of researching and manufacturing of light and heavy- duty H BEAM devices. To meet the demand of request, this welding line is only for light H lasers.
- H BEAM welding product line consists of IN Feed Conveyor to method Welder, In feed H BEAM
- Reducing welding deformation. It’s the complete device for delivering large volume

3. Working flowing
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.

Main Machine
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.
