AB  - Laser welding is a welding process with a high energy density and numerous advantages over conventional welding methods (narrow heat affected zone, lower heat input, less distortion, and the like.) Mechanical treatment laser is an innovative technique for improving the properties of fatigue resistance, abrasion and corrosion resistance. In this paper, mechanically processed by laser two groups of samples; base materials and laser welded joints. Sheets made of Ni superalloy 2mm thick -millisecond Nd: YAG laser, while the mechanical treatment made picosecond Nd: YAG laser. Welds are tensile tested, and microstructure was observed by optical and scanning electron microscopy. The microhardness was measured by Vickers method with a load of 10 N.
AB  - Lasersko zavarivanje je proces zavarivanja sa velikom gustinom energije i mnogobrojnim prednostima u odnosu na konvencionalne metode zavarivanja (uska zona uticaja toplote, manji unos toplote, manja distorzija i sl.) Mehanička obrada laserom je inovativna tehnika kojom se poboljšavaju karakteristike otpornosti na zamor, habanje i otpornost na koroziju. U ovom radu, mehanički su obrađene laserom dve grupe uzoraka; osnovnog materijala i laserski zavarenih spojeva. Limovi superlegure debljine 2mm su zavareni milisekundnim Nd:YAG laserom, dok je mehanička obada obavljena pikosekundnim Nd:YAG laserom. Zavareni spojevi su ispitani zatezanjem, a mikrostruktura je posmatrana optičkim i skenirajućim elektronskim mikroskopom. Mikrotvrdoća je merena po Vikersu sa opterećenjem od 10 N.

AB  - We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength of 1064 nm and a pulse duration of 170 ps. We employ different pulse energies and number of pulses. The spots appearing after the laser irradiation were examined by optical and scanning electron microscopy and analyzed by energy-dispersive spectroscopy. We also perform Vickers microhardness tests. We discuss the microstructure changes caused by different energy and number of pulses in air and in a He-enriched atmosphere with the aim to determine optimum laser parameters in surface-treatment technology.
