Micro-spot-welding of copper sheets with an IR vortex beam
文献摘要：
Copper welding with an infrared[IR]Gaussian laser beam usually shows obvious instability,spatters,and worse surface morphology due to the Gaussian distribution,temperature-dependent IR absorption,and high thermal conductivity in cop-per.In this paper,the IR quasi-continuous-wave Gaussian beam was converted into a vortex ring beam with a phase-plate and then applied to the micro-spot-welding of copper sheets.The welding with the vortex beam demonstrated a signifi-cantly improved welding performance,smoother surface morphology,and higher welding stability.Besides,no spatters appeared in the welding process.
