Essay

It is shown that main parameters of the process are: laser power, its distribution at the machining surface, focusing spot size, treatment speed, powder slowrite and direction of its feed. At nonuniform laser power distribution with intensity maximum shift to the border of focusing spot in the direction of processing it is possible to decrease significantly the level of residual stresses at cladded layer and even to avoid the crack formation.
