WY20 钇钨电极 WY(Yttrium- Tungsten Electrode)
钇钨电极在焊接时弧束细长、压缩程度大,在中、大电流时熔深比较大,
目前主要用于军事工业和航空、航天工业。
The Yttrium- Tungsten Electrode produces a slim arc when used
in welding .With a high level of compression, it has a bigger
melting depth in medium and high current .It is mainly in
the military, aviatic and astronautic industries.
