Gantry Welding Machine

There are two models, gentry automatic welding machine and T gantry automatic welding machine. It adopts A.C. Inverter control with functions of stable running and fast traveling speed. The seam-tracking arc-guide mechanism is three-spindle system to guarantee the alignment without aberrancy. The main frame and welding machine are integrated control. With flux auto-recovering system and it is easy to operate with high efficiency. T gantry automatic welding machine can weld two pieces of beam at the same time, and the web height of beam is not limited by the main machine.

1. The H beam gantry gate welding machine has two structures: Gantry gate move type & double cantilever move type.
2. Gantry gate or cantilever drive method: AC motor and R series worm reducer.
3. Welding speed: 0.15~1.5m/min.
4. Arc guide frame head function is to mechanically track up and down, left and right.
5. Imported frequency converter is able to realize gantry gate or cantilevers stepless speed adjustment, with wide speed adjustment range, high accuracy and constant output torque.
6. Electrical control cabinet includes main control cabinet and remote operation box.
7. Two work-piece at one time.

LHA-4000 Gantry type H beam automatic welding machine

1.Purpose and working principle
This machine is an ideal equipment for automatic submerged arc welding of H steel. The work piece is placed on the bracket of the work piece (Fig. 1), Tilt 45 degrees to make the weld to be the position of the ship. The welding arm with the embedded welding head can be horizontal and up and down movement on the cross beam of the gantry frame, so that the welding nozzle on the head can be aligned to the welding seam. The equipment at the front end of the welding arm has a welding machine automatic tracking device, and then the gantry frame goes in a straight line on the rail, automatic welding. This machine is equipped with automatic welding, recycling and processing equipment.
