Properties of the built-up metal
Wear resistance - high. Resistance to blows - satisfactory. The built-up metal usually is not processed. Formation of hair cracks which usually do not reduce operational firmness of details is possible.
Technological features
The shirokosloyny naplavka on the increased departure with oscillating motions of an electrode wire is recommended. The general thickness of the built-up layer has to be no more than 12 mm.
Application
Naplavka of teeths, peaks and walls of buckets of excavators, grid-irons of grokhot, knives of graders and bulldozers, gruntozatsep, links and asterisks of a running gear of track laying vehicles, driving wheels and snails of pump-dredges napeschany soil, slurry pumps, etc.
