| Abstract: | This research is based on the low energy green welding technology and theory. The interaction mechanism between the low power laser and welding arc is expounded. The innovative ideas are proposed in low power pulse laser induced arc hybrid welding process. The energy-saving hybrid welding technology system is established. The results of the study show that the welding arc energy density is increased by the low-power laser induced effect, which is used to achieve the favorite hybrid between laser and arc heat sources. The low-power laser induced arc hybrid welding technology is used to join Mg alloy, Ti alloy and Steel successfully. The development of the low-power laser induced arc hybrid welding technology provides obviously effect on the low energy green welding manufacture. |
