Description:

The welder transfers energy through an arc, generating high temperatures in the weld area, melting the weld material and the workpiece surface. This process forms a strong weld after cooling. The nozzle is the focal point of the welding arc and molten metal. It concentrates the current and heat, promoting metal melting and forming a uniform weld.

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.

Features：

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

2.Electroslag welding with a molten nozzle produces high-quality welds with low oxygen and impurity levels in the weld zone. This helps improve the weld's mechanical properties and corrosion resistance.

3.Electroslag welding with a molten nozzle uses a high-energy DC arc. The arc is formed within the nozzle, resulting in concentrated heat and high energy density. This helps quickly melt the workpiece surface and fill the metal layer, resulting in faster welding speeds.
