Radiators, electrodes
Electrodes for manual arc welding are up to 450 mm long rods from electrode wire with a coating layer, a mixture designed to boost arc stabilization, protect against adverse air impact and to provide metallurgical treatment of the welding bath.
- Ó – for welding of carbon and low-alloy structural steels;
- Ë – for welding of alloyed structural steels;
- Ò - äfor welding of alloyed thermally stable steels;
- Â - for welding of special property high-alloy steels;
- Í - for weld deposition of special property surface layer.
Metal electrodes for arc welding of steels and weld deposition are manufactured according to
GOST 9466-75
.
By their application, coated electrodes for manual arc welding are subdivided into following groups:
According to the type of coating the following electrodes are to be distinguished: acid - À, base - Á, cellulose - Ö, rutile - Ð, mixed type, other coating types - Ï
Electrodes are manufactured with diameters 3.0, 4.0, 5.0 6.0.
