Current and polarity
Direct current of reverse polarity (DC +, “plus” on the electrode).
Surfacing coefficient
15.0 – 15.5 g/ah
Consumption of electrodes
~ 1.5 – 1.7 kg per 1 kg of deposited metal
Application Area. ANZHR – 1 Welding Electrodes.
ANZHR-1 welding electrodes are intended for welding of heat-resistant steels with high-alloy heat-resistant steels, as well as for welding of hardenable steels without subsequent heat treatment and without preheating during the manufacture and repair of critical structures operating at temperatures up to 550-600°C. Welding in all spatial weld positions with direct current of reverse polarity.
Welding Technique. ANZHR – 1 Welding Electrodes.
Welding is performed with a short arc using direct current of reverse polarity (DC+) in all spatial positions, except vertical “top-to-bottom”.
The deposited metal is not prone to crack formation, which allows work without preheating and heat treatment. If the permissible moisture content in the coating is exceeded, the electrodes are baked at 190-210°C for 1 hour.
Regulatory Documents. ANZHR – 1 Welding Electrodes.
GOST 9466-75, GOST 9467-75.
Main Weldable Materials. ANZHR – 1 Welding Electrodes.
Welding of dissimilar joints (pearlitic steel + austenitic heat-resistant steel). Welding of hardenable steels without preheating. For structures operating at temperatures up to 550-600°C (steam pipelines, furnace elements, turbines, boilers).
Special Properties. ANZHR – 1 Welding Electrodes.
• Welding of dissimilar steels without preheating and heat treatment • Heat resistance up to 600°C • High corrosion resistance • Welding in all positions (except vertical)

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.
