The pulsed electron beam welding has bigger penetration,larger depth-width ratio and better weld seams performance compared with the traditional continuous electron beam welding.The key technology of the pulsed electron beam welding is that how to produce pulsed beam current by the gridbias power supply,thus,a discussion and comparison on gridbias power supply that can produce pulsed beam current were made and some experiments comparison between pulsed electron beam welding and con-tinuous electron beam welding were made.
