FIELD: process engineering.
SUBSTANCE: invention can be used for electrochemical protection of main pipelines, particularly, for welding cathode and drain bends to pipeline walls. Proposed composition comprises the following components in amount that follows, percent by weight, i.e. aluminium 8.0-8.4, copper 11.0-11.6, ferromanganese 12.8-13.3, plumbous orthoplumbate 1.5-5.0, copper oxide 66.7-61.7.
EFFECT: cheaper composition for aluminothermic welding.
