Abstract：The effect of pulsed laser welding current and pulse width on the weld forming of 0.5 mm copper sheet is studied by using XR-AW300 pulsed laser device.Under the conditions of defocus-2 mm, welding speed 80 mm / min, frequency 6 Hz and argon protection conditions, the laser welding current and pulse width parameters of high quality welds are obtained in the range of 200 ~ 215 A, 4.0 ~ 4.5 ms by observing the microstructure and microstructure of the weld.
