Gantry Double Cantilever H Beam Welding Machine 

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…
