VEPL has vast product range. We are offering over 200 types of electrodes including the following to our valued customer
In this type, about 35% in weight of the coating is titanium dioxide (TiO2) facilitates arc ignition, makes it possible to work with a soft arc and reduces spatter.
The coating of this type of electrode consists of calcium fluoride plus calcium and other alkaline carbonates. The coating is mostly thick.
The coating of these electrodes contains organic materials that turn into gases in the arc. About 30% of the coating weight is cellulose.
Basic (lime) coated electrode is designed for welding of high strength low alloyed (HSLA) steels. It gives Ni-Cu alloyed weld metal with crack resistant and high toughness. Specifically formulated for easy slag removal, strike and re-strike characteristics and low spattering.
These electrodes may have a rutile or basic coating. Basic coated ones are only used with DC (+). These electrodes have various types since they are used for welding martensitic, ferritic, austenitic, and corrosion-resistant steels which compositions differ from each other.
Some machinery parts may get out of shape due to one or more wearing mechanisms such us abrasion, adhesion, erosion, fatigue or corrosion. build-up welding is used advantageously for these and for the rebuilding of broken parts.
Cast iron may only be welded by specially designed electrodes having particular chemical, metallurgical and mechanical properties.
Specially produced acidic, rutile, cellulosic and iron powder electrodes 4 to 6 mm in diameter produce a cutting or gauging arc with a current intensity of 60-70 A/mm.
Metal Arc Welding (GMAW) is a welding process which joins metals by heating the metals to their melting point with an electric arc.
Frequently Asked Questions
What is Metal Recovery & how much is it for Prima 7018 (AWS: E7018) ?
Metal recovery is the ratio of weight of weld metal deposited to the weight of core wire melted. For Prima 7018 (AWS: E7018) metal recovery is 115% min.
What do you mean by Touch Electrode in Prima 6013 (AWS: E6013) ?
In cheaper electrode, usually welder faces a problem of arc striking or knocking of electrode before use, where as in Prima 6013 (AWS: E6013) can operate even with 50 OCV (Open Circuit Voltage) that is a special characteristic of "Touch & Start welding" without any hassle.
