Mechanical Performance of Fiber Laser Welded AA5182 weld characterization of aluminum alloys. They reveal the grain boundaries and weld zone microstructure. First of these was 0.5 ml HF in 100
Effects of Welding Speed on Microstructure and Mechanical The effects of welding speed on microstructure and mechanical characterization of welded joint of AISI316L austenitic stainless steel and EH36 ship steels using fiber laser welding were
Aug 01, 2017 · Mechanical characterization of the welded samples such as microstructural analysis, hardness, and tensile tests are conducted. It is noticed that the hardness value of the FZ is higher than the HAZ and BM zone due to the difference in cooling rate during welding which promotes the formation of martensitic phase in the FZ.
Microstructural and Mechanical Characterization of the Yb In this work, the Yb:YAG laser beam welding of the magnesium alloy AM60 was studied. A laser power of 2 kW and a welding speed of 3.5 m / min give a different welding quality than that obtained by CO2 laser with the same parameters. The metallurgical characterization, by optical microscopy, showed the formation of four distinct zones :base metal (BM), heat affected zone (HAZ), the partially
Microstructure and Tensile Behavior of Laser Arc Hybrid Microstructure and Tensile Behavior of Laser Arc Hybrid Welded Dissimilar Al and Ti Alloys focused on this work to reveal the joint characterization of laser-CMT hybrid welding of dissimilar Al and Ti alloys. Experimental Procedures The hybrid welding system integrated a fiber laser and a Fronius CMT welder. The laser beam was
The Effect of Process Parameters on the Microstructure and Mechanical Performance of Fiber Laser-Welded AA5182 Aluminium Alloys %K fiber laser welding, aluminum alloys, mechanical characterization; microstructural analysis %X The laser welding of aluminium alloys is an important industrial technology but many challenges remain.Microstructure-properties correlation in fiber laser Jun 23, 2014 · The fusion zone (FZ) in the DP welds consisted of fully martensitic structure; whereas HSLA and dissimilar weld FZ microstructure were mixture of martensite and bainite. Analytical transmission electron microscopy (TEM) confirmed bainite structures containing bainitic ferrite laths with intralath and interlath cementite.
