Boiler industry used membrane panel welding machine, panel and tube butt joint welding machine

1600*4 Membrane Panel Welding Machine
(Submerged arc welding method)



1. Equipment structure
- This equipment is composed of SAW machine (two sets of welding torch, the torch moving vertically and laterally, wire hanging feeding, wire calibration, flux recycling device, etc.), four sets of welding power source, electric control system (control box, operating boxes, etc.), transfer roller, compressed air and so on.
- Wire feeding, torch, electrical switches and other components, imported components recommended.
- In the process of welding together, the four sets of independent operation button, adjustable knob (including the regulation of welding, positioning cylinder mobile, etc.) and the regulated digital. display and dial plate should be in one box. Welding process can be manual or programmed.

2. Brief introduction
    Using four sets submerged arc welding sources process to weld tubes and flat bar into a single or even tube group, and to match 1600*4 the existing machine in order to increase the membrane welding ability in the shop.

4. Other requirements
- Feeding structure: feeding speed is synchronous with welding speed, that is 0.5-2.0m/min adjustable. Axis can be fitted a variety of roller into the above specifications tube with pneumatic clamping device.
- Two sets of side clamping mechanisms: by the center to the lateral movement is about 0-800mm, the same movement as left/right roller seat .the rear wheels with pneumatic devices, the pin adapted to the over-voltage roller of the above specifications tube, the rear of side clamping roller can calibrate the side bend, the movement of the side clamping roller with cylinder, the fine-tuning of which with manually.
- Work-piece can be into the corner.
- Flux recycling device: each group torch should be equipped with flux recycling device, the flux powder hopper with drying flux, which be taken into the parts to be welded, inhalation into welding flux tube after welding as recycling. the suction of powder suction machine should be sufficient, the flux tube should have sufficient capacity to ensure the normal welding. which should be accompanied a heating device and uniform heating, temperature control automatically, heating temperature is between 0-200 degree.
- Wire-assisted institutions: auxiliary wire feed speed is greater 3 times than feeding speed.  
- Welding speed: welding speed and welding in welding can be facility adjusted range 0-2.0m/min, each welding machine with speedometer or a digital display.
