H Beam Welding Machine
This machine is mainly used for submerged arc welding of assembled H beam, the working principle is as following:
1) One H-beam steel placed on workpiece support frame with 45°, which is suitable for boat type welding
2) Gantry welding machine walks on rails at adjusted welding speed
3) Use SAW welding to weld two seams
4) Arc-guide frame automatic seam tracking
5) Flux automatic feed and recovery system
Features:
1. The frame structure of gantry consists of walking beam, column and upper platform. Gantry adopts square pipe and channel steel structure, process stress relieving, with strong and stable structure.
2. Each of walking beams is driven by a motor reducer, forming a double-drive system, which makes the operation smooth and reliable.
3. The moving of gantry is frequency speed adjust controlled, the welding speed can be adjusted according to welding technology requirement.
4. The electric control system consists of one electric control box and two operation panels. The electric control box is equipped on a walking beam, while the 2 operation panels are fixed on the front of upper platform. They are placed separately, which is convenient for operation.
5. There’s seam tracking device fixed 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 deformation .
