Document Type and Number:
Japanese Patent JP2016055323
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electron beam welding method, a manufacturing method of an electron beam weld structure and the electron beam weld structure which suppresses a defect due to deviation and easily suppresses the deterioration of a mechanical property of a weld part.SOLUTION: An electron beam welding method includes: a process for forming a primary weld beam 11 so as to contain a bevel 7 disposed on an abutted part of two base materials 5; a process for successively forming a first secondary weld bead 12 and a second secondary weld bead 13 which have a width smaller than that of the primary weld bead 11 on such a position as to be brought into contact with the primary weld bead 11 over the whole thickness direction of the base materials 5 and that the first secondary weld bead 12 and the second secondary weld bead 13 are not superimposed on each other; and a process for forming a tertiary weld bead 14 which has a width smaller than that of the primary weld bead 11 on such a position as to contain the bevel 7 and as to be contained within the primary weld bead 11.SELECTED DRAWING: Figure 1E
