Gantry type welding machine

Gantry-type welding machine is mainly used for submerged ac welding H-beam from the gantry and two nose composed of two parts can be carried out on the ship at the same time the location of welding, of the bilateral synchronous drive mode, reliable and stable. Using three-axis mechanical seam tracing agencies can dynamically track the seam. AC frequency control system, speed range, torque large. Using two single-wire singe arc welders while weld.
