WT20 Thoriated Tungsten TIG Welding Electrode Description
Thoriated Tungsten Electrode is the most commonly used tungsten
electrode in DC welding environment, which often contains
1.70-2.20% rare earth element thorium, so the electrode head is
generally red. WT20 Thoriated Tungsten TIG Welding Electrode is
mainly made of powder metallurgy technology. Compared with other
tungsten electrodes, it has excellent electrical conductivity, good
high temperature resistance, strong current carrying ability, high
arc starting performance, long service life, resistance to arc
erosion, and higher pollution resistance. Low cost of consumption,
various advantages, can provide higher quality welding. WT20
Thoriated Tungsten TIG Welding Electrode is usually used for DC
welding of carbon steel, stainless steel, nickel alloy and titanium
metal, especially in the aerospace industry, military industry and
nuclear industry welding engineering occupies an important
position, even in the range of high current can work stably.
It should be noted that the electrode is slightly radioactive, and
long-term application may allow radioactive substances to enter the
body of the staff and cause chronic diseases, so in the case of
economic conditions, pollution-free lanthanum tungsten electrode
can be chosen to replace.
