FIELD: process engineering.
SUBSTANCE: invention relates to surfacing aluminium parts, particularly, turbojet blower jacket. Mask 30 with openings sized to surfacing area peripheral section and preset thickness is fitted in place. Said opening is aligned with surfacing area. Aluminium powder layer 9 is manually applied on part surfacing area 1 to cover partially said mask 30 around said surfacing area to level powder layer to preset height H relative to part surface S. Note here that said preset height exceeds mask thickness. Said powder layer is welded to said part by laser beam.
EFFECT: decreased amount of micro fractures and embrittlement.
