<p><P>PROBLEM TO BE SOLVED: To provide a method of welding metallic members, a method capable of welding even a combination of metallic members having different specific resistance values and capable of securing excellent welding quality at low cost. <P>SOLUTION: The method of welding metallic members includes: a tack welding process in which a projection Tc formed in a first metallic member 1c is oppositely superimposed on a second metallic member 2c, in which the first and the second metallic member 1c, 2c are energized while being pressurized by projection welding equipment, and in which the projection Tc of the first metallic member 1c is tack-welded to the abutting face 3c of the second metallic member 2c; and a laser welding process in which the tack-welded abutting face 3c is irradiated with a laser beam for fusion welding between the first and the second metallic member 1c, 2c at the abutting face 3c. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
