Grain refinement and laser energy distribution during laser oscillating welding of Invar alloy
Laser oscillating welding method was employed to welding of Invar alloy so as to achieve grain refinement and decrease internal defects. Effects of frequency and amplitude of beam oscillation with sinusoidal trajectory on weld appearance and solidification microstructure were researched. The essenti...
