Electroslag welding system with trolleytype nozzle (IGBT)

Quick Detail:

This system consists of one ZH7 series electroslag welding power source and one WT-ZH nozzle electroslag welding carriage. It utilizes the resistance heat generated by the current passing through the molten slag as the heat source to fuse the workpiece and filler metal into a weld seam in a vertical position.

1.It is particularly suitable for welding partition plates of box-shaped columns/beams, and the equipment is easy to operate.

2.Nozzle electroslag welding can achieve high-quality weld seams, with a lower oxygen content and fewer impurities in the welding area. This helps improve the mechanical properties and corrosion resistance of the weld.

3.Nozzle electroslag welding uses a high-energy DC arc, which is formed inside the nozzle, concentrating heat and increasing energy density. This facilitates the rapid melting of the workpiece surface and filler metal, resulting in a fast welding speed.

Description:

The welding machine transfers energy through an electric arc, generating high temperatures in the welding area to melt the welding material and the surface of the workpiece. After cooling, a strong weld seam is formed. The nozzle is the focal point of the welding arc and molten metal; it concentrates the current and heat, promoting metal melting and ensuring the formation of a uniform weld seam.

Applications:

The ZH7 inverter electroslag welding machine is a high-efficiency, energy-saving DC power source that adopts IGBT inverter technology. It can weld carbon structural steel, low-alloy structural steel, heat-resistant steel, and composite steel materials.
