The Effect of Shielding Gas Flow Rate on Fiber Laser Welding of Boron Steel

During laser welding process, the ionized metal vapor from keyhole surrounding by molten metal mixes with the shielding gas and forms a plasma plume over the molten pool. The small amount of plasma plume is needed to react with molten pool by enhancing the absorption of laser energy thus increase th...
