Trans. Nonferrous Met. Soc. China 24(2014) 2208-2213 Effect of Si content on laser welding performance of Al-Mn-Mg alloy Pi-zhi ZHAO1,2, Jing LIU1, Zhi-dong CHI1 1. Suzhou Research Institute... content (0.1%-0.5%, mass fraction) and pulse laser welding performance of Al-Mn-Mg aluminum alloy sheets was studied. The sheets were fabricated in the laboratory, with gauge of 0.45 mm, H16 temper......
. This simplification is far from the actual condition in laser welding. In order to study the energy coupling between laser and material during laser welding, a focused laser beam with real Gaussian intensity..., the plasma plume exits above the keyhole and the keyhole contains partially ionized keyhole plasma during laser welding of metal materials. The laser beam transports partial energy to the inverse......
: The effect of laser beam welding (LBW) process on the microstructure-mechanical property relationship of a dissimilar weld between the copper (Cu) and stainless steel (SS) was investigated. Backscattered... into the local microstructural gradients across the weld. Key words: laser beam welding; copper; stainless steel; microstructural characterization; tensile property; impact toughness 1 Introduction......
words: laser welding; keyhole; weld pool; edge; image processing algorithm 1 Introduction Since laser beam welding has the characteristics of high efficiency, high energy density, low heat input, large ratio of weld penetration to width, less thermal distortion and easy controlling parameters, it is widely used in industries. During the process of laser beam welding, many factors, such as laser......
. The TC4/TA15 dissimilar joints failed in the TA15 BM, and had characteristics of ductile fracture at different strain rates. Key words: laser beam welding; titanium alloy; dissimilar joint; strain rate... and laser beam welding (LBW). LBW has drawn particular attention on titanium welding because of its high energy density, low residual stress and high productivity. Compared with electron beam welding, LBW......
