Electrodes ANO-21 are characterized by high technological properties, especially easy primary and secondary ignition and slag crust separation. The weld metal has a high resistance to external influences, even in sub-zero temperatures. Electrodes may also suitable for welding water pipes, low-pressure gas pipelines.
PURPOSE AND FIELD OF APPLICATION
Designed for manual metal arc welding of structures from mild steel according to ДСТУ 2651/ГОСТ 380 (Ст 0, Ст 1, Ст 2, Ст 3) of all groups and all degrees of disoxidation – "Rimmed" (“КП”), "Semi-killed" (“ПС”), "Killed" (“СП”) and ГОСТ 1050 (05кп, 08кп, 08пс, 08, 10кп, 10пс, 10, 15кп, 15пс, 15, 20кп, 20пс, 20).
APPLICATION CONDITIONS
Deposition rate factor – 7,0-8,0 g/А.hr. Electrode consumption per 1 kg of weld metal - 1,65 kg. Electrodes “ANO-21” suitable for welding of corner, butt and lap joints in all welding positions. Welding in vertical-down position carried out by deep-penetration method, herewith electrode must be in bisector flat area and the travel angle may vary 40 – 70°. It is allowed to weld with an elongated arc over clean surfaces.
REDRYING BEFORE WELDING
At the normal storage conditions, redrying is not required. In case of moisture the redrying is made at 120±10°С for 40 min.
