1. Classified by power source: A: A power frequency type: conventional power frequency wire mesh welding machine, the most used one at present. B: Intermediate frequency type: The welding power source is a gantry welder with an intermediate frequency inverter. Because of energy saving, it is a trend in the future. C: Three-phase secondary rectification type: Welding power supply adopts three-phase secondary rectification or single-phase secondary rectification welding power source. It is mainly for welding products such as steel grids as shown below: 2. According to the electrode head classification, there are 5 gantry wire mesh welding machines[1], 8 gantry wire mesh welding machines, 10 gantry wire mesh welding machines, 12 Head gantry wire mesh welding machine, etc., can be customized according to requirements. 3. According to the degree of automation, there are semi-automatic gantry wire mesh welding machines and fully automatic gantry wire mesh welding machines. Among them, the most famous automatic gantry wire mesh welding machine in China is the Jun Evapotranspiration brand.

3.feeding device gantry welding machine needs to choose a feeding device

1) Manual feeding device: manually place the workpiece, manually put the workpiece into the mold, start the welding machine to weld one row of the workpiece in turn, and then advance to the next station to continue welding the next row, until the complete workpiece is welded. The manual feeding device has the characteristics of low equipment cost and high work intensity.

2) Semi-automatic feeding device: manual placement of the workpiece, automatic stepping feeding, the workpiece will automatically stop when the transverse iron wire reaches the welding station. The welding machine welds one row of workpieces in turn, and then automatically feeds to the next row, and automatically welds until the entire workpiece is welded, and the workpieces automatically return or exit from the rear. It can improve production efficiency, reduce labor intensity, and improve welding quality. Semi-automatic single-mode gantry wire mesh welding machine Semi-automatic single-mode gantry wire mesh welding machine.

3) Automatic dual-mode feeding device: double-layer automatic feeding and welding device, using advanced PLC programmable controller and flexible man-machine interface control, and precise servo motor drive system to form a continuous automatic feeding and welding mechanism. Welding has two sets of front and rear workpiece molds. When one mold is welding, the other mold places the workpiece. After welding, the two molds exchange positions, and continue to weld and place the workpiece. Efficiently improve the work efficiency, and through the adjustment of the man-machine interface, it is convenient to weld meshes of different widths.

Advantage 2:

1. Electric welding or projection welding of multiple solder joints can be completed uniformly at one time, and the welding efficiency is higher.

2. Configure the control box to switch between different welding specifications, that is, one control box controls one welding spot, which can control different output currents, and the time parameters are suitable for welding of stiffened plates, laminates, etc.

3. The electrode adopts the welding pressure method with auxiliary stroke, which makes the welding product suitable.
