Description
X-ray images emitted from the beam hole have been observed by a pin-hole camera method. The behaviour of the front wall of the beam hole during electron beam welding has been analysed by a high speed movie and a streak photograph. In case of single electron beam welding, the scraping process of the front wall, the formation process of spiking and the suppression mechanism of welding defects by the beam oscillation method have been revealed. It is found that the front wall of the beam hole is not always scraped uniformly but it is scraped by the locally melted region on the front wall. The suppression mechanism of defects by the Tandem Electron Beam Welding Method has been also analysed. It is compared with that of the beam oscillation method in ordinary single electron beam welding. It is suggested that the Tandem Electron Beam Welding Method is much more effective.
