Abstract

Essential features in the dynamic behaviours of welding and cutting processes with high energy density beams are reviewed and clarified by the efficient usage of various cineradiographic diagnosises. Formation of a deep beam hole in the weld pool are described and the important effect of the front wall characters in the beam hole is demonstrated on the natures of deep penetration and defect formations such as spiking and porosity. The cutting process is also interpreted in the frame of the same physical viewpoint with the welding. A new and efficient suppression method of spiking, porosity and humping are examined and confirmed using Tandem Electron Beam developed by the author.
