The store has many electrodes that are suitable for arc welding. Some of the models can be used for surfacing metal. The main parameters of the electrodes include the maximum voltage deviation, temporary resistance and diameter.
Also, the electrodes differ in the consumption of deposited metal. Models are sold on the market in packs of 20-50 pieces. On average, they cost from 500 rubles.
How to choose electrodes?
To work with the pipeline, it is more advisable to select electrodes with a small parameter of the nominal voltage. Many models are available with cellulose coating. They are excellent for surfacing surface layers. It is also important to note that the parameter of temporary resistance should be no more than 300 MPa. To select electrodes for working with carbon steel, it is necessary to look at rutile-coated models. The nominal voltage deviation should be about 6 V. On average, the parameter of temporary resistance should be 350 MPa. Good electrodes in our time will cost 600 rubles.

Relative elongation of the brand is at the level of 20%. Temporary resistance is not more than 45 MPa. If you believe customer reviews, then the model is suitable for work on the pipeline. With metal structures of various shapes, problems also rarely arise. This brand is sold in packs of 15 and 40 pieces. The price of such products ranges around 600 rubles.
Application of electrodes OK-46 4 mm
Electrodes OK-46 reviews are mostly positive. First of all, they differ in high-quality coating. To work on pipelines, the brand is used quite often. Directly, the parameter of temporary resistance is not more than 55 MPa. A significant diameter of the electrodes allows you to perform complex work with metal surfacing. The sensitivity to the edges of the model is low.
If you believe the owners, then the flow rate of the weld metal is within normal limits. However, there are still drawbacks. First of all, welders complain about rust sensitivity. Before using electrodes, the work surface must be cleaned for a long time. Under alternating voltage, the model cannot be used. The minimum allowable angle of the electrode is 35 degrees. Impact strength of the presented brand is at the level of 77 J. The user can buy OK-46 electrodes at a price of 650 rubles.
Model OK-46 5 mm
The presented OK-46 electrodes are sold with a cellulose coating. According to the owners, the model is well suited for surfacing metal. The threshold voltage with reverse polarity does not exceed 12 V. For welding with a short arc, the presented mark cannot be used. The maximum allowable angle of inclination is 75 degrees. The parameter of temporary resistance lies in the region of 300 MPa. The coating itself is provided with a small thickness. However, the consumption of this model is not very high. The user has the opportunity to buy OK-46 electrodes at a price of 650 rubles.
Model Abicor Binzel
These electrodes for metal surfacing are very popular. First of all, it is important to note that they are ideally suited for arc welding. Sensitivity to rust is low. The index of temporary resistance does not exceed 33 MPa. In this case, the minimum allowable angle of inclination is about 35 degrees.
If we talk about the minuses, then the welders note a large consumption of deposited metal. For a ceiling seam, the brand does not fit well. The threshold voltage with reverse polarity does not exceed 9 V. The deposition coefficient of such products is not more than 8 g. Electrodes can be bought in the store for 570 rubles.
Askaynak Characteristics
These electrodes are characterized by low sensitivity to any contamination. Thus, the work surface can not be greatly prepared. The brand is suitable for arc welding. The coating in this case is made of cellulose. The parameter of temporary resistance fluctuates around 340 MPa. According to the welders, the seam is neat. The relative elongation of the indicated brand fluctuates around 25%. However, it is important to note that she is afraid of slag leakage. Also, these electrodes have metal spray problems. For carbon steel, the brand is not unique. You can buy it in the store at a price of 800 rubles.
Linkoln Electrode Application
These electrodes are suitable for working with edges as well as piping. They are also often used for welding metal structures. The threshold voltage of the brand with reverse polarity is at 22 V. The temporary resistance of the electrodes does not exceed 360 MPa. In this case, the minimum allowable angle of inclination is 23 degrees. For metal surfacing, the brand is often used. The seam in this case is pretty neat.
If you believe the reviews of the welders, then the consumption of the electrodes is quite significant. The rust sensitivity of the brand is low. The presented model is not afraid of slag leakage. The user can buy electrodes at a price of 760 rubles.
Model Lincoln Electric
These electrodes are quite common. In this case, the impact strength is at the level of 22 J. The brand is not very sensitive to pollution. However, buyers note that for an even seam, the work surface should be carefully cleaned. The specified model is not suitable for work on the pipeline. This is largely due to the small allowable angle of inclination.
The parameter of the temporary resistance of the electrode is 300 MPa. The surfacing coefficient, in turn, does not exceed 9 g. If you believe the welders, then you can work with carbon steel calmly. The threshold voltage with direct polarity is at 12 V. Buy electrodes for 570 rubles.
