Thorium Tungsten Electrode Characteristics and Thorium Tungsten Electrode Application

Thorium tungsten electrode characteristics

Thorium oxide containing tungsten thorium ( thorium dioxide or thoria ) , in the United States it is most commonly used tungsten electrodes , determine other tungsten electrodes have become a standard of good or bad . However, since this has a low level of tungsten electrodes radiological hazards , many users have switched to other options. In general , a 2% thoriated tungsten electrode is a relatively good tungsten electrode having the lowest work function , even when the overload voltages also performed well . Thorium tungsten electrode performance in many respects superior to pure tungsten electrodes . Than pure tungsten thorium oxide provides about 20 percent higher than the current carrying capacity , generally longer life , but also help prevent contamination when welding . Using thoriated tungsten electrode , arc easier than that of pure tungsten electrode and the arc or zirconium tungsten electrodes more stable. Thorium tungsten electrode 1% (EWTh - 1) and thorium tungsten electrode 2% (EWTh - 2) can be used for DCEN. They remain in the welding process sharpened tip , which can be used to weld steel pipe , not usually direct current, because it is difficult to maintain a spherical tip welding without cracking , which is a must for direct current .

Thorium tungsten electrode application

Thoriated tungsten electrodes are usually used for the DC negative electrode or carbon, stainless steel, nickel alloys, titanium alloys and other applications of the positive electrode . Their operating performance , even when the overload current of the operation can be very good .

Thoriated tungsten electrode is usually used in the field of carbon and stainless steel . Thorium oxide content of 2% thoriated tungsten electrode is typically less than 1% of the thorium content of the tungsten electrode to better improve performance . Communicate using thorium tungsten electrode welding, faster , and to be used with caution in order before welding on AC DC welding reaction . In AC welding, balled balls will not melt, so the effect is not as liquid ball so well.

Thoriated tungsten electrodes are usually used for DC welding field, while pure tungsten electrodes for AC welding . During the welding process , the staff should carefully read the instructions for use of thorium tungsten electrode .
