FIELD: process engineering.
SUBSTANCE: metal powder is placed on metal screen pre-welded to part surface. Powder is compacted by pressing it into metal screen mesh aperture by inking roller with its width that of the latter. Screen thickness defines the resulted coating thickness. Part with welded on powder is fed under roller electrode for powder to be welded on.
EFFECT: controlled coating thickness, better coating quality.
