2.4 Tungsten Electrode

TIG welding commonly use cerium tungsten electrode as welding electrodes (tungsten needle). DC current for 2.4 tungsten electrode in TIG welding is 150 ~ 250A, AC current is 80 ~ 150A( when positive and negative half wave are balance). Thoriated tungsten electrode is a kind of rare earth tungsten with the outstanding overall performance. This type of electrode can withstand overload currents, which is widely used in the United States and other countries.

1.6 Tungsten Electrode

1.6 tungsten electrode is tungsten needle, and its diameter is 1.6mm. Wherein 1.6 thorium tungsten electrode (red head electrode) is a traditional electrode type, it has a good welding function. The arc would not break, scatter, splash in the welding process. It has stable arc and thermostability, its tungsten head can be maintained in the round shape for a long time. In addition, 1.6 tungsten electrode has a long service life.

Minimally Invasive Tungsten Needle Electrode

Precision and accuracy of minimally invasive tungsten needle electrode has always been an essential tool for highly difficult operative approach, its ultra-fine tungsten tip can be used in a variety of muscle space. Early in the 19th century, Smith-Peterson approach (DAA) had been reported. With increasing of minimally invasive surgery in the past decade, people think highly of operative approach. Stryker minimally invasive wolfram needle electrode benefits the doctors who explore the DAA approach. Minimally invasive wolfram needle can facilitate the use of DAA and reduces complications, avoid intraoperative muscle damage, reduce postoperative pain, accelerate postoperative recovery, reaching a better clinical effect.

Minimally invasive wolfram needle electrode can reduce surgical injury, shorten the operation time, and improve the postoperative recovery, accelerate cutting speed. What's more, it has high blood coagulation efficiency with safe operation.

Tungsten Needle Holder

Shape of tungsten needle tip is a critical factor for TIG welding. When using DCSP, electrode tip should be tip shape, and tip angle should be changed with the different ranges of applications, electrode diameter and welding current. Narrow joints need smaller tip angle, when welding very thin material, it requires low current to stabilize the arc. 


Conventional electrode sizes are Ø1.6mm, Ø2.4mm and Ø3.2mm, so the size of the tungsten electrode holder may also be given in accordance with the diameter of these specifications. Special specifications are Ø4.0mm, Ø6.0mm, Ø8.0mm and so on.

Tungsten Needle Electrode

Tungsten needle electrode is a kin of tungsten electrode whose diameter is between 0.2 ~ 1.0mm, because it is very thin, this type of electrode is called as a wolfram needle electrodes. Tungsten needle electrode is an elongated structure tungsten products which is made of pure tungsten or tungsten alloy. It is mainly used in the electrode material of argon arc welding technology, the instrument can also be used as probes. Tungsten needle electrode is ultra-sharp electrode with a blunt head and sharp end.

WZ8 Zirconiated Tungsten Electrode

Introduction

WZ8 zirconiated tungsten electrode contains about 0.8% zirconium dioxide, and the number 8 refers to content of the zirconium tungsten electrode. The best advantage of zirconium tungsten electrode is that the electrode tail can maintain the state of the ball even under high load current conditions, so that it can avoid the contamination of workpiece in welding to a certain extent. Therefore, WZ8 zirconium tungsten electrode has become the best choice to replace pure tungsten electrode for majority of businesses.

Trademark

WZ3 and WZ8 are the main two trademarks of zirconiated tungsten electrode, which are named in according with the content of zirconium oxide. Zirconium tungsten electrode also contains about 98% of tungsten.

Code	Impurity	Impurity Content%	Othere Impurity%	Electron Work Functon	Color
WZ8	ZrO2	0.70 - 0.90	< 0.20	2.5 - 3.0	White

Characteristic

Tip of WZ8 zirconiated tungsten electrode is white. WZ8 zirconiated tungsten electrode contains about 8% zirconium dioxide, which can improve the efficiency of arcing and its AC welding. Compared to pure tungsten electrode, zirconium tungsten electrode can maintain good arc stability. The most important point is that it can prevent workpiece from being influenced by the W after melting to a large extent in the case of the high load current. Excellent corrosion resistance is a major feature of WZ8 zirconium tungsten electrode.

Content

Zirconium dioxide is an oxide whose hardness only to diamond. It can be prepared by zirconium oxychloride fumed, colloidal, dipping, hydrolysis, high temperature hydrolysis method, alkoxide solution. This type electrode also contains a little yttria, also known as yttrium oxide.
