Product Description

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.

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.
