- In detail
Electrodes of the LEZ UONI - 13/55 brand are intended for manual arc welding of especially responsible designs from carbonaceous and low - alloyed staly when impose increased requirements on plasticity and impact strength to metal of welded seams, especially during the work in the conditions of the lowered temperatures. Welding in all spatial provisions, except vertical from top to down, a direct current of the return polarity.
The recommended value of current (And)
Special covering of products on the basis of carbonates and fluoric connections thanks to which as a part of a seam gases, nonmetallic inclusions and other undesirable impurity practically do not contain;
Basic material for a core of electrodes is the wire from low - carbonaceous steel Sv - 08 or Sv - 08A which provides durability and high viscosity of a seam;
in the course of drawing a covering on an electrode basis, it is given additional durability, and roughnesses, teases, superficial cracks, swellings and a time are absolutely excluded at the same time;
Absence in a covering of electrodes of organic inclusions allows to calcinate electrodes at a temperature of 350 - 400 degrees, than their low susceptibility to moisture influence is provided.
