Power Electrical Technology
Welding is a traditional fabrication or
sculptural process that joins materials, usually metals or
thermoplastics by power electrical technology application. There are
many different types of electrodes used in the shielded metal arc
welding. The TIG electrodes are widely used as joining process in
numbers of many areas. While the aerospace, mechanical industries are
one of the primary users of tungsten welding electrodes.

Pure
tungsten and containing various oxide additive tungsten electrodes
1. Range of
use :apply to protecting arc welding with inert gases and plasma
jointing ,cutting ,spraying and smelting.
2. Properties of the products :high melting point ,steady electric arc
,without self-consume .Tungsten increasing 0.15-4% Tho 2 ,Zro 2 ,Lao 2 ,Ceo
2 ,which can reduce the loss of tungsten pole ,prolong its life ,not
pollute the welding seam ,increase launching ability of tungsten pole
electrons and so on Therefore ,the quality of welding seam is high.
3. Export tungsten electrodes execute ISO 6848 international standard
and AWS5.12,,the chemical composition of major tungsten electrodes see
Table 1.
4. Size and size tolerance: diameter:
Φ0.1~15mm
tolerance: ≤ Φ2.5 mm 士0.05mm ; > Φ2.5
mm 士0.1mm
Length:
150mm, 175mm, 178mm,or by customized
request. Length tolerance:±1mm
5. Flat degree :not large 0.5% length of electrodes.
6. Quality of surface :smooth ,clear ,no defect ,no greasy dirt and
other impurity.
7. The end surface of electrodes should be even ,smooth and no burrs
,the section has no internal defect.

Molybdenum WIRE for
Wire cut Electrical Discharge Machining (WEDM)
We specify
the high quality molybdenum raw material, with the special-purpose
equipment, special craft manufacture. The company cuts the
special-purpose molybdenum wire to each line to carry on the tensile
strength, the elongation ratio, the luster, the precision, the
platoon line altogether six quality examinations separately, strictly
controls molybdenum to leave the plant the quality. The molybdenum wire
tensile strength excel 30% than the local national standard GB , with
the higher tensile strength, the smaller elongation ratio , better
uniform good characteristic. Cutting ability when discharges the
performance well, cuts the superficially attractive fineness to be high;
When use tight wire few, stability good, cuts the precision to be high;
Also may enlarge the high frequency power, enhances the rough machining
work efficiency.
