Color of tungsten electrodes
Are you interested in the color of tungsten electrodes from the supplier company AvecGlob? Here you will find interesting information on this topic
General Provisions
Color marking of tungsten electrodes is regulated by the following standards — for domestic products GOST 23949−80 «Tungsten welding electrodes, non-melting. Technical Specifications «, for imported production electrodes — ANSI / AWS ISO 6848 standards.
Each of the types of tungsten electrodes has its own rational applications:
Clean tungsten electrodes are used for welding aluminum and its alloys, not suitable for DC welding;
Torated electrodes are used, if necessary, to improve the arc burning characteristics;
Zirconia electrodes do not contaminate the welding seam, they are used for welding aluminum alloys, but are not suitable for DC welding processes;
Lanthanide electrodes are distinguished by light arc ignition, can be used both on permanent and alternating current, are used for welding of unalloyed and high-alloy steels; aluminum, titanium, nickel, copper and magnesium alloys, as well as for microplasma welding;
Cerium electrodes also facilitate arc ignition, are suitable for DC and AC welding, can be used for welding of unalloyed and high-alloy steels and aluminum, titanium, nickel, copper and magnesium alloys, but both in the lower and in the middle range of the welding current
