FIELD: metallurgy.
SUBSTANCE: overlay welding is performed using a filler metal wire made of aluminium alloy, whose composition is identical to that of the deposited aluminium alloy parts to obtain rolls of large cross section. Thermal welding cycle is selected from the condition of minimum residence time in the range of weld metal embrittlement aluminium alloy by controlling the pulse rate of the filler wire feeding rate and welding.
EFFECT: implementation of cladding without hot cracking.
