Abstract The violent interaction between the high-energy laser beam and the 2195 Al-Li alloy dramatically disturbs the fluctuation behavior of the molten pool during welding process, which results in the poor forming quality and severe porosity defects. In this paper, an emerging coaxial hybrid heat source consisting of a 1080nm fiber laser and a 915nm diode laser is employed in the welding of 2195 Al-Li alloy in order to obtain the more stable molten pool. The distribution characteristics of the fiber-diode laser beam intensity were researched to reveal the energy coupling mechanism. The is-situ observation experiment More >
