XBH-1150 type cantilever submerged arc welding machine
Working principle of cantilever welding machine is as following:
1）one H-beam steel placed on 60°degree turning frame with 45°,which is suitable for boat welding
2）cantilever welding machine walks on rails at adjusted welding speed
3）use SAW welding to weld one seam
4）arc-guide frame automatic seam tracking
5）flux automatic feed and recovery system

Technical details:
This machine is made of trolley, vertical column, cross beam, drag plate mechanism, seam tracking device, wire feeding device, wire reel supporter, flux recovery system, electrical control system and SAW welding power.
Trolley is composed of one base, four walking wheels, two power wheel shaft and two motors. These two motors drive four walking wheels through gears to form a four-wheel drive system, thus can make the movement smooth and reliable. One flux recovery machine and one SAW welding power are placed on the base.
The upright column has big-sized structure which can greatly improve the machine’s rigidity. There is electrical control box and operation panel in upright column.
Upper cross beam is square pipe structure, which has light weight and good rigidity. Rails and racks on upper cross beam can drive drag plate and welding arm move horizontally on it.
Welding arm is the most important part for welding work, it can move horizontally on cross beam together with drag plate, also can move up and down on directional wheel of the drag plate .
Seam tracking device is placed under welding beam, it has the function of automatic tracking, which can keep suitable distance between welding gun and welding seam, it has auto compensation function for H-beam‘s deformation .
Wire feeding device is fixed in arc-guiding device, it can connect wire feeder and wire reel together by wire feeding pipe.
Wire reel supporter is used for fixing wire reel, place wire reel into the supporter before welding, then make wire thrill through feeding pipe and connect it to feeding machine.
Flux recovery system is composed of flux recovery machine, flux cylinder, flux bucket, flux feeding pipe, flux recovery pipe and so on. They work together to realize automation of flux feeding and recovery process.
Electrical control system is fixed in upright column. While operation panel is on electrical control box’s panel. The electrical control system control movement of trolley, up-down of welding arm, start and stop of SAW welding power, start and stop of flux recovery machine and so on. The movement of trolley is frequency speed adjust controlled, the welding speed can be adjusted according to welding technology requirement.
SAW welding power is an important part for welding work; we usually equip ZX5-1000 with this machine, also can equip American Lincoln DC-1000 or SAW welding power of other brands.
