Electrodes MR-3 provide high-quality weld seam, weld metal resistant to porosity and hot crack formation, easy gaps overlapping. Characterized by a high level of welding and technological properties, simple welding process, easy secondary ignition while tacking. Highly valued by welders for both domestic and industrial use. It is allowed to weld an elongated arc over an oxidized surface.

PURPOSE AND FIELD OF APPLICATION

Electrodes for manual arc welding, MP-3 designed for welding of structures made of low carbon steels according to ДСТУ 2651 / ГОСТ30 (Ст0 і Ст1, Ст2, Ст 3, Ст all, Ст 20 degrees deoxidation "КП", "ПС", "СП") and ГОСТ 1050 (05кп, 08кп, 08пс, 08, 10кп, 10пс, 10 15кп, 15, 20кп, 20пс, 20).

APPLICATION CONDITIONS

Deposition rate factor – 8-8,5 g/А.hr. Electrode consumption per 1 kg of deposited metal is 1,7 kg. Suitable for corner, butt and fillet joint types on metal with 3-20 mm thickness. Electrodes with diameter range from 3 mm to 4 mm designed for welding in all positions, 5 mm diameter electrodes – for horizontal flat, horizontal down hand, transverse and vertical up positions.

REDRYING BEFORE WELDING

At the normal storage conditions, redrying is not required. In case of moisture the redrying is made at 140±10°С for 40 min.
