What Is Tungsten Wire for Diamond Wire Busbar?

Tungsten wire for diamond wire busbar, also known as Tungsten cutting wire, tungsten wire rope or tungsten-based diamond wire, is a kind of diamond wire with pure tungsten wire or doped tungsten wire as the busbar. It is widely used in wire cutting industry because of its excellent cutting effect.

Advantages of Tungsten Wire as Diamond Wire Busbar

Diamond wire is one of the important tools for cutting silicon wafers that are one of the core components of photovoltaic equipment. The bus bar in the wire is mostly made of carbon steel wire, but studies have shown that fine tungsten wire can replace carbon steel wire thanks to its good characteristics of high tensile strength, high rigidity, good toughness, low torsional stress, fatigue resistance and corrosion resistance.

The purpose of replacing with this metal wire is to deal with the problem of thin wire. At the same time, this wire’s fracture force is proportional to the wire diameter and tensile strength. At present, the wire diameter of high carbon steel wire (busbar) is close to the limit. Fine tungsten wire has stronger tensile strength and can make the wire diameter thinner under the same breaking force.

Compared with made of high carbon steel wire, the wire with tungsten wire as the busbar has a smaller diameter, higher breaking force and better durability, so it is more suitable for application in the future photovoltaic Industry.

Applications of Tungsten Wire as Diamond Wire Busbar

It is is mainly used for cutting and processing highly hard and brittle materials, such as crystalline silicon, sapphire, cemented carbide, optical glass, ceramics, magnetic materials, stone, etc.

What is Tungsten Filaments?

Tungsten filaments, also called cathodes or electron emitters or electron sources, are mainly made of high-quality tungsten. Of all pure metals, tungsten has the highest melting point (3422°C), the lowest vapor pressure at temperatures above 1650°C, and the highest tensile strength. Tungsten also has the lowest coefficient of thermal expansion of all pure metals. This combination of properties makes tungsten an ideal material.

Why Tungsten Filaments Are Used in Electron Gun?

Tungsten can be used in both thermionic electron guns and field-emission (CFE) electron guns. Electron beams come from filaments made of various materials. The most common is the tungsten hairpin gun, which is widely used in scanning electron microscopes, transmission electron microscopes, and microprobe systems. This filament is a tungsten ring that acts as a cathode. Apply voltage to the loop to heat it up. The anode, which is positive relative to the filament, forms a strong attraction to electrons. This causes electrons to be accelerated towards the anode. Some accelerate near the anode and down the column to the sample.

Why Are Tungsten Filaments in the Electron Gun Folded?

An electron gun works at a high temperature, which is required for thermionic emission. For this, a filament or the cathode should be of a material that has a high melting point in order for it to continuously emit electrons. Tungsten filament is folded with various shapes to help in focusing the electron beam.

What Is Thoriated Tungsten Electrode?

A Thoriated Tungsten Electrode is a type of tungsten electrode used primarily in Tungsten Inert Gas (TIG) welding and plasma arc welding (PAW). It is made by adding thorium oxide (ThO₂) to tungsten, typically in concentrations of 1% (WT10) or 2% (WT20) thorium.

Properties of Thoriated Tungsten Electrodes

Higher Electron Emission – Thorium improves electron emission, making arc starts easier and more stable.

Improved Arc Stability – Provides a smoother, more stable arc, reducing arc wander.

Higher Current Carrying Capacity – Can handle more current compared to pure tungsten, leading to better performance in DC welding.

Increased Electrode Life – More resistant to wear and contamination, resulting in a longer lifespan.

Good Resistance to Contamination – Less prone to oxidation and contamination than pure tungsten electrodes.

Applications of Thoriated Tungsten Electrodes

DC TIG Welding: Primarily used for welding carbon steel, stainless steel, nickel alloys, and titanium.

Aerospace and Industrial Welding: Due to its longevity and stability, it is widely used in precision welding applications.

Plasma Cutting and Welding: Works well in plasma arc welding (PAW) and plasma cutting torches.

What is Cerium Tungsten Electrode?

Cerium tungsten electrode (WC20) is alloyed with about 2% cerium oxide. It is a non-radioactive, refractory or non-consumable metal electrode material, which is the preferred substitute for thorium tungsten electrodes. Regular diameter of the electrode is between 0.5mm and 12.0mm, and the length is 150mm and 175mm.

Characteristics of Cerium Tungsten Electrode

The addition of this small percentage of cerium oxide increases the electron emission qualities of the electrode which gives them a better starting characteristic and a higher current carrying capacity with no spitting. With the increase of cerium oxide content, the ablation resistance and arc starting of cerium tungsten electrode will increase; with the increase of use time, the welding performance will gradually decrease.

Cerium Tungsten Electrode Applications

The electrode has excellent arc starting properties at low current, and can operate successfully with AC or DC electrode negative. If used on higher current applications, the cerium oxide may be concentrated to the excessively hot tip of the electrode. In addition, WC20 is also used in inert gas shielded arc welding, hydrogen atom welding, argon arc surfacing, pulse argon arc welding, plasma welding, plasma cutting, plasma spraying, plasma melting, etc. The welding materials can be carbon steel, stainless steel, silicon copper, copper, bronze, titanium and so on.
