Prices for welding electrodes
Type of coverage
Basic. Provides stable arc burning and formation of a high-quality deposited layer.
Current and polarity
Direct current of reverse polarity (DC+). Some manufacturers allow operation on alternating current.
Surfacing coefficient
10.00-11.0 g/ah
Consumption of electrodes
~ 1.4 – 1.5 kg per 1 kg of deposited metal
Application Area. OZN – 6 Welding Electrodes.
OZN-6 electrodes are intended for manual arc welding surfacing of rapidly wearing parts of mining, construction machinery and other equipment operating under conditions of intense abrasive wear and significant impact loads. Surfacing in flat and horizontal-vertical positions with direct current of reverse polarity.
Surfacing should be performed with a short arc on a cleaned surface, as the deposited metal is prone to porosity formation. If the permissible moisture content in the coating (0.7%) is exceeded, the electrodes must be additionally baked before use at a temperature of 280-300°C for 40-60 minutes.
Welding Technique. OZN – 6 Welding Electrodes.
Surfacing is recommended to be performed with minimal heat input, avoiding excessive overheating of the part. Before applying the subsequent layer, the previous one must be thoroughly cleaned of slag and spatter. To relieve stress, forging of the deposited beads with light hammer blows is recommended.
Regulatory Documents. OZN – 6 Welding Electrodes.
GOST 9466-75, GOST 9467-75.
Main Weldable Materials. OZN – 6 Welding Electrodes.
Surfacing of rapidly wearing parts operating under conditions of abrasive wear and impact loads.
Special Properties. OZN – 6 Welding Electrodes.
The electrodes provide deposited metal with increased resistance to crack formation during multi-layer surfacing and under operating conditions with intense impact loads. The deposited metal has high abrasive resistance due to alloying with chromium and boron.

All covered electrodes are sensitive to moisture absorption. Excessive moisture content in the coating can lead to porosity or hydrogen cracking.
However, if the climatic storage conditions meet the following requirements, moisture absorption by the electrodes is minimal:
• 5–15°C at a maximum relative humidity of 60%
• 15–25°C at a maximum relative humidity of 50%
• >25°C at a maximum relative humidity of 40%
At lower temperatures, maintaining the storage temperature 10°C above the ambient temperature is sufficient to achieve the required moisture content level. Cold packages must be allowed to warm up to ambient temperature before opening.
At higher temperatures, the required moisture content in the air can be achieved by dehumidification. The shelf life of electrodes under the above conditions shall not exceed three years.
• Covered electrodes with a basic coating and low hydrogen content must be baked prior to each use whenever requirements regarding the content of diffusible hydrogen and/or the soundness of the deposited metal are specified.
• Stainless steel electrodes with a basic coating may produce porosity during welding if the humidity levels during their storage did not meet the requirements. To restore their original properties, they also need to be baked.
• Electrodes for welding carbon steels with a cellulosic or rutile coating typically do not require baking.
• Electrodes that have suffered serious damage due to exposure to moisture cannot be restored by rebaking and must be rejected.
