英文摘要: Inconel alloy 617 was used in the present research because of its high strength and oxidation resistance in a wide range of temperatures. In this investigation, full-penetration welding of 1.5-mm-thin Inconel 617 plates in a butt configuration was carried out with a fibre laser welding machine of 400 W. The influence of different welding conditions, such as welding speed, welding power on the heat-affected zone morphology, metallurgy and mechanical properties has been discussed in detail in this study. Microstructures have been assessed by optical microscope and by field emission scanning electron microscope. On the other hand, mechanical behaviour has been analysed in terms of Vickers microhardness and compared with specimens of base materials under different welding conditions. Tensile...
