2. Description:
This machine is made of trolley, vertical column, upper platform, tool carriage mechanism, seam tracking device, wire feeding device, wire reel supporter, flux recovery system, electrical control system and SAW welding power.
The gantry frame is formed by the walking beams, the columns, and the upper platform. Each of walking beams is driven by a 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 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.
