Electrodes Monolith Professional provide easy primary and secondary ignition. Characterized by a calm and stable arc, low spatter loss, good slag separation, excellent seam formation. They are used for welding both direct and alternate current for connection of sheet steel and steel constructions undergoing static and dynamic loads, welding of tanks and pipelines, where high mechanical properties of joints are required. Electrodes are suitable for welding in conditions, improper for other brands of electrodes.

PURPOSE AND FIELD OF APPLICATION

Electrodes MONOLITH Professional are designed for manual metal arc welding at direct or alternate current of common and critical structures from carbon steel according to ДСТУ 2651/ГОСТ 380 (Ст 0, Ст 1, Ст 2, Ст 3) of all deoxidation degrees – "Rimmed" (кп), "Semi-killed" (пс), "Killed" (сп) and ГОСТ 1050 (05кп, 08кп, 08пс, 08, 10кп, 10пс, 10, 15кп, 15пс, 15, 20кп, 20пс, 20), suitable for corner, fillet and butt welding of metal from 1,0 to 20,0 mm thick. 

APPLICATION CONDITIONS 

Deposition rate factor – 8,0-9,0 g/A.hr. Electrodes consumption per 1 kg of weld metal is 1,7 kg. Electrodes from 2,0 to 4,0 mm diameter are designed for welding in all the spatial positions except vertical down, 5,0 mm diameter – for flat, horizontal and vertical up positions.

REDRYING BEFORE WELDING

At the normal storage conditions, redrying is not required. In case of moisture redrying is made at 105±5°С for 60 min.
