Introduction

Welding Electrodes are the essential components in the process of welding. Technically the welding electrode is made up of two parts; first is the actual metal which is formed into wires and cut into specified length and second is the flux coating which begins the chemistry role. The metal core covered by the coating in the electrode is called the welding core. The welding core is generally a steel wire with a certain length and diameter. During welding, the welding core has two functions: one is to conduct the welding current, generate an arc to convert electrical energy into heat energy, and the other is to melt the welding core itself as a filler metal to fuse with the liquid base metal to form a weld.

Flux coating dies

The process of manufacturing welding electrodes consists of various machines which include extrusion press, wire feeder, dry mixer, etc. The coating of the flux on the metallic rod is done by the extrusion press. Flux coating die is also known as coating die or covering die. The main task of this part is to coat the flux paste on the wire surface. The task of all hydraulic equipment is to create a proper pressure at the beginning of the inlet of this part and the paste is coated with the same density on the surface of the wire. The manufacturer selects this part with the appropriate hole diameter according to the diameter of the cover. Important parameters in this equipment are inlet geometry and hole length.

 

Benefit

We make tungsten carbide flux coating dies with superior raw material, supplying dimensions with a wide range of bore sizes, diameters, and lengths. It also comes with suitable angles, tolerances, and overall finishes. Flux coating dies have the capacity to draw tons of wire for electrodes, so the carbide material used can withstand the high pressures and temperatures involved in the coating process.

• Even coating: Carbide powder covering dies ensure even distribution of the flux mixture onto the wire.
• Extended die life: The carbide material used in the dies is able to withstand the high pressures and temperatures involved in the coating process, ensuring that the dies can be used repeatedly with minimal wear and tear. They are efficient, reducing production time and costs.
• Versatile: These carbide extrusion dies can coat a range of wire sizes and shapes, offering flexibility in production. Carbide coating dies produce a high-quality coating, improving the quality of the final product.
