T Type Double Column H Section Steel Welding Machine

T type Double Column H Section Steel Welding Machine Structure Principle:

Double column H section steel submerged arc welding machine is composed by moving trolley,flux transport and recovery system, electrical control system, SAW source etc.

Moving trolley is composed by union of two moving beams,vertical column, up platform, welding arm and tool carriage, welding seam tracking system, wire feeding device, wire reel supporter. The moving trolley is driven by two motors speed-reducer, the system is double driving, which insure the moving stable and reliable. 

Welding arm is the most important part for welded H beam, 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 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 composed of one electrical control box and two operation boxes, the electrical control box is fixed on one moving beam, the two operation boxes is fixed on the up platform. 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 H beam welding; we usually equip Zhouxiang MZ-1250 with this machine, also can equip American Lincoln DC-1000 or SAW welding power of other brands.

T type Double Column H Section Steel Welding Machine General Drawing:

H beam two arc two wires welding system can improve working efficiency highly.   

High-quality variable frequency motor can ensure stable and reliable welding process of H-beam

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

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 30~50m/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 conductive to reducing welding deformation and preventing metal overheating. In addition, the welding 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.
