Descripción del producto

Pure tungsten and WT, WL, WZ, WC, WY 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.***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 ***8 international standard and AWS5.*2, , the chemical composition of major tungsten electrodes see Table 1. 4. Size and size tolerance.diameter:Φ0.***5mm Diameter tolerance:≤Φ2.5mm±0.*5mm, >Φ2.5mm±0.1mm , 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.
