FIELD: metallurgy.
SUBSTANCE: invention relates to welding and can be used for manual arc welding of steels. Electrode for arc welding consists of metal rod and two-layer coating applied on surface of this rod. One of layers contains slag-forming and gas-forming components, and the other layer consists of activating components in the form of powdered mixture with binder. Layer of activating components has a higher melting point relative to the first layer. Opal-quartz-carbonate clay is used as activating components, and liquid glass is used as binder component. Coating provides welding arc conjugation due to high activating properties of electrode coating composition.
EFFECT: proposed electrode for arc welding.
