AC Frequency Converter Submerged Arc Automatic Welding Machine H Beam Production Line

The welding machine has a simple and reliable structure and a clever layout.

Main drive of gantry welding adopts imported AC frequency converter to control the synchronous speed-regulating drive on both sides, with stable speed and reliable linear speed digital display.

The H-beam submerged arc welding machine is equipped with a three-axis mechanical tracking arc guide device, pneumatic tracking up and down, floating tracking left and right, to ensure that the welding gun is accurately centered on the weld. The switch-on arc welding power source is installed on the gantry and moved along the gantry, so that the control cable and the welding cable are short, the response is fast, the voltage drop is small, and the welding current is stable.

The welding control and the door frame control are integrated, and the operation is simple. The welding arm cable adopts drag chain form, which is neat and safe.

Characters:
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.
