Abstract

PURPOSE: To control the defect of a spike, etc. by forcibly deforming to the ellipse that its major axial direction intersects at right angles each other at the vicinity of the surface of the body to be welded and the vicinity of the penetration root part the shape of the electron beam on the electron beam axis and vertical plane.
CONSTITUTION: The electron beam shape control device 3 composed of the plural magnetic poles or electrodes having ≥two poles under the convergent lens 2 is set up to control the shape on the electron beam axis and vertical cross section. The welding is performed by adjusting the major axis in the elliptical shape of the electron beam so as to become in the weld line direction as the 5b close to the surface of the body to be welded and in the right angles direction with the weld line as 8b close to the penetration root part. In this case, the molten metal is smoothly flowed out of the inside of the electron beam hole 11, the local hollow of a solidified wall 10 is dissolved and the porosity and solidification crack are prevented due to the electron beam hole 11 being enlarged in the weld line direction by the electron beam 5b close to the surface of the body to be welded. In the vicinity of the root part the control in the spike and cold shut can be performed in partial penetration welding by the electron beam 8b.
