WC20 鈰鎢電極
2026-01-06 鈰鎢電極
鈰鎢電極沒有放射性污染，屬于綠色環(huán)保鎢制品，僅用很小的電流就能輕松起弧，而且維弧電流也較小。在低電流直流的條件下，鈰鎢電極備受歡迎，尤其用于管道和細小部件的焊接、斷續(xù)焊接和特定數(shù)目的焊接是更具優(yōu)越性。
The Brief Introduction of WC20 Grey Tungsten electrodes
Ceriated Tungsten Electrodes which contains a minimum of 97.30% tungsten and 1.80 to 2.20% cerium, was known as the first non-radioactive alternative to 2% thoriated tungsten electrode. It is especially excellent for DC welding with low amperage because it starts very easily at low amperages.
Application
China Ceriated Tungsten Electrode is commonly used in welding orbital tube ,pipe and small or delicate parts. Like thorium, it is best used to weld carbon steel, stainless steels, nickel alloys and titanium, making it an obvious replacement for 2% thoriated tungsten electrode.
This tungsten electrode is used primarily for DC welding and may split if used for AC welding. 2% Ceriated tungsten electrode features slightly different electrical characteristics than thorium but most operators won’t be able to tell the difference. Using 2% Ceriated tungsten electrode at higher amperages is not recommended. In these situations, the oxides will migrate quickly to the heat at the tip, removing the oxide content and nullifying its process benefits.
