Interference of geometrical product specification caused by interaction of concentrated energy fluxes

The manuscript presents changes of geometrical product specification (GPS) in different materials that were subjected to point and linear interactions of laser flux and to helium and argon plasma beams generated in electric arc. The growth of laser flux energy density leads from surface heating to evaporating and material sublimation, and causes increase of surface roughness with cracks. The growth of electric arc energy causes increase of crater diameter of partial meltings and increase of surface roughness of partially melted materials.
