Sharpening of tungsten electrodes

Sharpening of tungsten electrodes

Are you interested in sharpening tungsten electrodes from the supplier company AvecGlob? Here you will find interesting information on this topic.

Necessity of operation

Sharpening of tungsten electrodes is used to increase the density of thermal power of the arc discharge. This allows for the same parameters of the welding current and operating voltage on the arc to achieve an increased concentration of heat and a bath with molten metal. Properly honed electrode also improves welding performance and reduces electrode wear, especially in those technologies where longer welding times are required, as well as automated welding with tungsten electrodes.

Sharpening of tungsten electrodes is realized on grinding machines with the help of a tool of their electrocorundum, one of whose surfaces has a smaller, and the second — a larger grain.

Supplier — AvekGlob Company — offers at affordable prices from the manufacturer tungsten non-consumable electrodes of various diameters and chemical composition. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Basic methods of sharpening

For success requires the use of timely wetting the working surface of the grinding wheel (using ordinary water) and a well-adjusted machine that do not allow vibration of the tool even with a large number of revolutions.

Important is also the right choice of material — soft circles wear relatively quickly, so you often need to stop the sharpening process to change or replace the circle, which reduces productivity. In many cases, the same materials are used for grinding the electrodes as for grinding carbide tools.

In the presence of only a hand grinder, the diameter of the grinding wheel can not be more than 80… 120 mm, with a grain size of about 120. However, this method of sharpening does not result in positive results due to large vibrations and difficulties in fixing the grinded electrode.

For grinding tungsten electrodes, the method of chemical grinding can be applied, when a special composition is applied to the end. Chemical sharpening is faster, and does not require significant effort. In addition, this method is insensitive to the degree of surface contamination of the electrode, especially when it was intensively used before sharpening.

Sequence of sharpening

  • The tungsten electrode is clamped into the cartridge of a hand drill;
  • The drill is brought to the side surface of the stationary grinding wheel;
  • The rotation shaft of the grinding machine is blocked;
  • Grinding is performed, with periodic blowing of surpluses from the sharpened end of the electrode.

Supplier — AvekGlob Company — offers to purchase tungsten non-consumable electrodes of various diameters and chemical composition. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
