 The application of the workpiece web height :200-1500mm 
 Length of workpiece: 4000-15000mm 
 Gauge: 4000mm 
 Rail length: 18000mm 
 Welding speed: 150-2000mm/min 
 Welding position: boat-shaped welding 
 Wire Size: 3.2-5mm 
 Flux recovery machine: 100kg x 2 
 Main power: 11KW (excluding two submerged arc welding machine) 
 2) performance characteristics 
 LHA type gantry H beam welding machine factory is based on the particularity of H-shaped steel boat welding combined with the factory for many years technical experience and development into the development of welding equipment, has a simple structure, reasonable layout, etc., and its main transmission adopts imported AC bilateral synchronous speed drive inverter control, speed and stability, the figures show that the line speed, reliability, and there arc bodies of the three-axis mechanical tracking guide, the upper and lower pneumatic tracking, rotation around the floating track, to ensure the torch accurate welds . Submerged arc welding power set in the gantry frame of the vehicle move, so that the welding machine control cable and welding cable is short, and thus feedback of performance, fast response, low pressure drop, accurate and stable welding current. Welding control and control integration gantry linkage control, easy to operate and reliable welding arm cable wiring using imported towline form of reliable, safe and beautiful.
