Tungsten Electrode Diameter Selection and Tungsten Electrode Packaging

The tungsten electrode is divided into different types according to different raw materials and doping elements, including pure tungsten electrode, thorium tungsten electrode, lanthanum tungsten electrode, zirconium tungsten electrode, yttrium tungsten electrode, cerium tungsten electrode and composite electrode. Due to their different materials and doping elements, different tungsten electrode has different characteristics and its applications are also different. In the tungsten electrode series, pure tungsten electrode is the cheapest, usually used in aluminum, magnesium alloy welding. Yttrium tungsten electrode in the welding process has slim arc, high compressive strength and high penetration in welding, which is mainly used in military and aviation industry. Thorium tungsten electrode overall performance is good and it has good performance in the overload, generally used for carbon electrode and stainless steel, nickel alloy and titanium electrode welding in the negative or positive electrode of direct current. Lanthanum tungsten electrode conductivity is generally good for welding carbon, stainless steel, nickel alloy and titanium. Cerium tungsten electrode can arc easily and also can stable maintain the arc, usually used for TIG welding, plasma welding, plasma cutting, plasma spray coating, plasma smelting and gas discharge light source. Composite tungsten electrodes added with two or more rare earth oxides has good welding performance which is better than thorium tungsten electrodes.

Tungsten electrodes common diameters are 0.5 ~ 50 mm and lengths are 150 mm, 175 mm and 178 mm. In the welding process, in different welding current tungsten electrode diameter is different, so tungsten electrode diameter selection depends on current.

Tungsten Electrode Packaging: Tungsten electrode packaging depends on the size of the product. Conventional electrodes of 150 and 175 mm length are available in plastic boxes with 5 / box and 10 / box. When the electrode length is longer, such as 200mm, 300mm, 400mm, 450mm, etc. can be bundled through the plastic film and packed with plastic box. This method can also be used in electrodes with a shorter length, which can save a fraction of the shipping cost.
