Remote fibre laser welding of advanced high strength martensitic steel [Elektronski vir]Prijanovič, Urban ...The study presents the results of remote robotic laser welding of advanced high strength Docol [registered trademark symbol] 1200 M martensitic steel. One mm thick samples were welded in a lap joint ... configuration using a special clamping system. Welding was done using a continuous-wave (CW) fibre laser with a constant welding power of 300 W and constant focus diameter Ø 1.8 mm. Welding was done using 12 different welding speeds in the range from 0.15 to 1 m/min, whereas the inclination angle was kept constant at 0°. The influence of various welding speeds and linear heat inputs during welding on microstructural changes were examined by the occurrence of acicular and allotriomorphic ferrite or martensite. Results revealed big influence of the clamping system on the accumulation of the laser beam energy, heat sink and consequently weld size and geometry, as well as its microstructure and joint strength. Tensile-shear strength, microstructure and hardness results confirmed laser power of 300 W and 0.6 m/min welding speed as the optimal parameters, at which a martensitic structure was obtained in the weld. The width of the heat affected zone (HAZ) in this case is 1100 [micro] m.Vir: Metals [Elektronski vir]. - ISSN 2075-4701 (Vol. 10, iss. 4, Apr. 2020, f. 1-14)Vrsta gradiva - e-članekLeto - 2020Jezik - angleškiCOBISS.SI-ID - 17165571
