Welding electrodes with the main covering UONII-13/55, are intended for welding of especially responsible designs from carbonaceous and low-alloyed staly when increased requirements on plasticity and impact strength are imposed to metal of welded seams. Are recommended, in particular, for welding of the designs working in the conditions of the lowered temperatures (-40 °C). A core from a wire of SV-08, SV-08A in accordance with GOST 2246-70. Diameter of the let-out electrodes 2,0; 2,5; 3,0; 4,0 and 5,0 mm.
Special characteristics of electrodes of UONI-13/55:
Metal of a seam is characterized by high resistance against formation of crystallizational cracks and the low content of hydrogen. Welding should be made a short arch by an opiraniye method. The welded edges have to be cleared of scale, a rust and traces of oil.
Application of welding electrodes of UONI-13/55:
Welding of especially responsible metalwork working under dynamic loadings in the conditions of negative temperatures, vessels working under pressure, a ship-building metalwork. Welding of metal of big thickness. Tea leaves of defects of molding.
Technological features of welding by UONI-13/55 electrodes:
Welding is made a short arch on the cleared edges.
Calcination before welding is obligatory: 150-180 C; 0,5 h.
Other goods: cement, slate, slag stones, plates, brick, electrodes, crushed stone.
