釷鎢電極   WTh(Thorium- Tungsten Electrode)
 
釷鎢電極是一種廣氾使用的添加氧化物電極，它有比純鎢電極及其它氧化物添加電極還要優越的綜合焊接性能，在長期使用過程中，它是其它氧化物電極所不可替代的。釷鎢電極操作簡便，電流負荷大，引弧容易，電弧穩定，斷弧間隙大，損耗小，使用壽命長，再結晶溫度更高，導電率更好，機械切割性能好。釷鎢電極廣氾使用於碳鋼、不鏽鋼、鎳合金和鈦金屬焊接，是高品質焊接的首選材料。

  
It is widely used as an additive oxide electrode ,having much more advanced comprehensive welding performance than the properties of Pure Tungsten Electrode and other additive oxide electrodes. It can not be replaced by other oxide electrodes during the long use process. It can be operated easily and current load is high .It can produce arc easily and steadily ,and the gap of the  breaking arc is big ,loss less and long life .It has much higher recrystallizing temperature, much better conductivity and better mechanical cutting property .It is used for welding carbon steel, stainless steel, nickel alloy and titanium metal. It is the first selection material for high quality welding.

特色：

釷鎢電極是最早使用的稀土鎢電極，綜合性能優良，尤其能承受過載電流，是目前美國和其它一些國家應用最廣氾的

鎢電極，在全球範圍內該品種鎢電極市場佔有率最高。但由於存在輕微的放射性污染，其在某些方面的應用受到象征

限制。釷鎢電極通常用於碳鋼、不鏽鋼、鎳合金和鈦金屬的直流焊接。
