Description

DESCRIPTION

The electrodes are designed for welding critical structures of low-carbon and low-alloy steels, when the weld metal is subject to increased requirements for ductility and toughness, especially when working in low temperatures, as well as for welding rotary and non-rotary joints of main pipelines. Can be used for root passages when welding pipes.

Welding can be performed in all spatial positions, except vertical top-down. The electrodes are sensitive to the formation of pores in the presence of rust and oil on the edges of welded parts, as well as increasing the length of the arc.
