20.500.12556/RUL-105771 Annular laser beam cladding process feasibility study In the paper a novel annular "ring shaped" laser beam cladding head and related cladding process are presented. In the cladding head a laser beam is shaped into an annular ring and guided coaxially with the powder tube disposing the powder jet in the centre of the focused annular laser beam ring. An experimental process feasibility analysis was performed using a Nd:YAG pulsed laser system with a maximal average power 250 W. Beside the known influencing parameters of laser cladding process including the powder mass flow, workpiece feeding velocity, and laser beam intensity, the important parameters related to the annular laser beam caustics were defined. The process feasibility and influence of the process parameters on powder catchment efficiency was analysed based on the cladding experiments of SS 316L powder on SS 304 workpiece material. The potential benefits related to the annular laser beam melt pool geometry and related powder catchment efficiency are discussed. annular laser beams powder cladding process parameters powder catchment efficiency kolobarjasti laserski žarki navarjanje prahu procesni parametri izkoristek prahu true false true Angleški jezik Slovenski jezik Članek v reviji 2018-12-13 09:50:30 2018-12-13 09:50:31 2022-08-18 03:45:57 0000-00-00 00:00:00 2016 0 0 F. 647-656 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535(045) 1875-3892 10.1016/j.phpro.2016.08.067 14887195 14886427 RAZ_Kuznetsov_Alexander_i2016.pdf RAZ_Kuznetsov_Alexander_i2016.pdf 1 52D0D5DCD74AF3EFB03BCD92D49E6F19 b67343c47c881bb72d010af08252f144d32df44bb57736caa59d3ec055baa201 35fa2ac9-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116452 http://www.sciencedirect.com/science/article/pii/S1875389216301742 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116451 Fakulteta za strojništvo 0 0 0
