H beam Submerged Arc Welding Machine/Automatic SAW Welding

Gantry Type H - beam Welding Machine 

Gantry Type H-beam Welding Machine Introduction:

   The H beam gantry welding machine is formed by two walking beams, two elevating arms and the upper platform. Each of walking beams is driven by a AC motor reducer, forming a double-drive system, which makes the operation smooth and reliable. On the front of the platform, there are rails and racks, and they can be used to make the welding arms and tool carriages move. And two sets of wire and flux recovery machines can be put on the platform.

Welding arm is the most important part for welding work, it can move horizontally on cross beam together with tool carriage, also can move up and down on directional wheel of the tool carriage .
   Seam tracking device is placed at the head of the welding arm, 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 H beam; we usually equip Zhouxiang MZ-1250 with this H beam gantry welding machine, also can equip American Lincoln DC-1000 or SAW welding power of other brands.

H beam Gantry Welding Machine Details:

Two welding arms can weld two H-beam at the same time:

Welding head can also use 2 arc 2 wire type, which is suitable for thick plate welding:

One worker can operate the machine easily by control box in center:

We use good brand components mainly Schneider in electrical cabinet:

Why we often use Submerged arc welding way in the H beam productions line?

The weld seam of H-beam is very long. So continuous automatic welding is possible. In addition, submerged arc welding has many advantages：

1. High welding productivity: Submerged arc welding can use a large welding current, the arc heating is concentrated, and the molten pool depth is increased. The welding speed of submerged arc welding is fast, and the welding speed of single wire submerged arc welding can reach 30~50 m/h.

2. Good welding seam: the surface of the molten pool is protected by slag and flux, which avoids metal oxidation reaction in the molten pool and improves the strength and toughness of the welding seam. At the same time, due to the fast welding speed and relatively reduced heat input, the width of the heat affected zone is smaller than that of electrode arc welding, which is conducive to reducing welding deformation and preventing metal overheating. In addition, the weld surface is smooth and beautiful.

3. Improve the working conditions of welders: because the automation of the welding process is realized, the operation is relatively simple, and the arc burns under the flux layer without the harmful effect of the arc, so the mask can be omitted, and at the same time, less smoke and dust are emitted, so the working conditions of the welder are improved.

4. Save welding materials and electric energy: Due to the large welding seam depth, no or less grooves can be opened during submerged arc welding.
