WT20 / WT10 / WT30 / WT40 Thoriated Tungsten Electrode

タイトルまたは説明

1)Dia: 1.0 **0.0mm
2)Length of tungsten electrode:*5mm, **0mm,**5mm,**8mm
3)Quality:Ground/Polish Finish; Annealed/Unanneale

 Best stability at medium currents, good arc starts, medium tendency to spit, medium erosion rate 

1)  Thoriated tungsten electrodes (AWS classification EWTh*2) contain a minimum of *7.*0 percent tungsten and 1.*0 to 2.*0 percent thorium and are called 2 percent thoriated.

They are  most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current-carrying capacity.

This electrode operates far below its melting temperature, which results in  a considerably lower rate of consumption and eliminates arc wandering for greater stability.

These electrodes are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.**0 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium.

2)  Color mark: Red (WT*0/EWTh*2)
3)  Diameter: 1.0mm***0.0mm

 0.**0" (1.0mm), 1/*6" (1.6mm), 3/*2" (2.4mm), 1/8" (3.2mm) and 5/*2" (4.0mm)
4)  Length: 6'' (**0mm), 7''(**5mm & **8mm)
5)  Quality of surface: ground finish, polish finish

We  can make different  kinds of diameter and  length  tungsten electrodes according to clients' requirement.
