The store features a variety of electrodes,which are suitable for arc welding. Some of the models can be used for surfacing metal. The main parameters of the electrodes are the maximum voltage deviation, time resistance and diameter.
Also, the electrodes differ in the consumption of the weld metal. Sold models on the market in packages of 20-50 pieces. On average they cost from 500 rubles.
It is more expedient to work with the pipelineto select electrodes with a small parameter of nominal voltage. Many models are available with cellulose coating. For surfacing of the surface layers, they fit perfectly. It is also important to note that the time resistance parameter should not exceed 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 time resistance parameter should be 350 MPa. Good electrodes in our time will cost 600 rubles.
For work with carbon steel are usedOK-46 (electrodes). Characteristic of them is quite good. In particular, the time resistance parameter is 400 MPa. In this case, the cracks on the seams can easily be cleaned. For AC operation they are suitable.
The coating is made of cellulose.This model is not suitable for pipeline operation. The threshold voltage for direct polarity is not more than 75 V. The electrodes are not afraid of large overheating. You can find them in packages of 20 and 30 pieces. They cost an average of 500 rubles. Certificate OK-46 from the National Academy of Control and Welding received.
For surfacing of metal, OK-46 is used(electrodes). Characteristic of them is similar to the previous model. In this case, the coating is provided from cellulose. The threshold voltage for direct polarity is not more than 55 V. The parameter of the temporary resistance is at the level of 40 MPa. If you believe the feedback of buyers, then the model is well suited for working with carbon steel and stainless steel.
The flow rate of the weld metal is small.For DC welding, the model is not suitable. It is also important to note that OK-46 electrodes differ by a small deviation of the nominal voltage. If you believe the owners, then the sensitivity to rust is moderate. The minimum allowable angle of the electrode is 36 degrees. To the pollution, the brand is quite sensitive. Buy electrodes (welding) OK-46 user can only in packs of 50 pieces. They cost in the market around 750 rubles.
These electrodes OK-46 (GOST 9466-75) areinexpensive and characterized by increased viscosity. In many respects this became possible due to the application of rutile coating. The relative elongation of the mark is at the level of 20%. The time resistance is not more than 45 MPa. If you believe the feedback of buyers, then the model is suitable for working on the pipeline. With metal structures of various shapes, problems also rarely arise. This stamp is sold in packs of 15 and 40 pieces. The price for such products fluctuates around 600 rubles.
Electrodes OK-46 reviews are mainlypositive. First of all, they are distinguished by a high-quality coating. For working on pipelines, the brand is used quite often. Directly, the time resistance parameter is no more than 55 MPa. The significant diameter of the electrodes allows you to perform complex work with the deposition of metal. Sensitivity to the edges of the model is low.
If you believe the owners, then the expense of depositedmetal is within normal limits. However, there are still drawbacks. First of all, welders complain of sensitivity to rust. Before using the electrodes, the working surface must be cleaned for a long time. With an alternating voltage, the model can not be used. The minimum allowable angle of the electrode is 35 degrees. The impact strength of the presented brand is at the level of 77 J. The user can buy the OK-46 electrodes at a price of 650 rubles.
The presented OK-46 electrodes are sold withcellulose coating. According to the owners, the model is well suited for surfacing metal. The threshold voltage for reverse polarity does not exceed 12 V. For welding with a short arc, the brand can not be used. The maximum allowable angle of inclination is 75 degrees. The parameter of the 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. Buy electrodes OK-46 the user has the opportunity at a price of 650 rubles.
These electrodes for metal deposition are veryin demand. First of all, it is important to note that they are ideally suited for arc welding. The sensitivity to rust is low. The indicator of the time resistance does not exceed 33 MPa. In this case, the minimum allowable angle of inclination is about 35 garusov.
If we talk about the minuses, then welders notehigh consumption of weld metal. For the overhead seam, the brand is not suitable. The threshold voltage for reverse polarity does not exceed 9 V. The coefficient of surfacing of such products is no more than 8 g. You can buy electrodes in the store for 570 rubles.
These electrodes are characterized by low sensitivityto any pollution. Thus, the work surface can not be strongly prepared. For arc welding, the brand is suitable. The coating in this case is made of cellulose. The parameter of the temporary resistance fluctuates around 340 MPa. According to welders, the seam turns neat. The relative elongation of this grade fluctuates around 25%. However, it is important to note that it is afraid of slag flowing. Also, these electrodes have problems with spattering of the metal. For carbon steel, the brand is not suitable unambiguously. In the store it can be bought at a price of 800 rubles.
These electrodes are suitable for working with edges, andalso a pipeline. They are also often used for welding metal structures. The threshold voltage of the mark with the reverse polarity is at the level of 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 welding metals, the brand is used frequently. The seam in this case turns out rather neat.
If you believe the reviews of welders, the consumption ofelectrodes is quite significant. The sensitivity to rust in the brand is low. The presented model is not afraid of slag. The user can buy electrodes at a price of 760 rubles.
These electrodes are quite common.In this case, the toughness is at the level of 22 J. The dirt is not very sensitive to soiling. However, buyers note that for a smooth seam work surface should be carefully cleaned. This model is not suitable for pipeline operation. In many respects it is connected with a small allowable angle of inclination.
Parameter of electrode temporary resistanceis equal to 300 MPa. The surfacing coefficient, in turn, does not exceed 9 g. If you believe the welders, then it is possible to work with carbon steel safely. The threshold voltage for direct polarity is at the level of 12 V. You can buy electrodes for 570 rubles.
