Base electrode for welding of aluminum alloys, and also wearproof and corrosion-resistant coverings on steel, cast steel, and cast iron, especially on blanks which are subject to erosive wear. The electrode is also suitable for filling of defects of casting on aluminum (bronze casting), can be used as the bearing material for the high pressure loading. Mechanical properties of deposit are very good, with acid environments, in sea water, erosive resistance. This electrode can be used as a component in the worn-out details, for example, as bearings of sliding and slide tracks.
DC electr. +
Annealing for 2h at 200-250оС. Joints before welding must be clean from oil and cracks.
Welding must be with a short arc and without high power.
