    摘要： In a secondary battery, for providing a structure which can enable a welding operation even when a gap is formed between a current collecting plate and a winding assembly, recessed portions are formed in a positive current collecting plate. The recessed portions are disposed opposite to the winding assembly. A laser beam is irradiated to welding protrusions located between the recessed portions to melt the welding protrusions. Here, since the end surface of a positive electrode foil is uneven in height, the positive electrode foil does not contact the positive current collecting plate necessarily. The welding operation is performed by heating, melting, and dropping the welding protrusions by the use of a YAG laser under the welding condition of a laser power of 900 W and a welding speed 2 m/min.

    摘要： A problem of FSW spot-welding is that a bonding strength tends to be low, since an area of metallic bonding is limited to the neighborhood of a pin portion of the welding tool.In order to solve the problem, after a tool (1) is inserted into a member (4) to be welded, a rotation shaft of the welding tool is tilted around a predetermined point (13) as a fulcrum, and the tip portion of the welding tool (1) is swung to enlarge a plastic flow area caused by rotation of the tool. As a result, the welding strength can be increased.

    摘要： The present invention provides a friction stir welding method in which a plurality of members are lapped and a welding tool is pressed into one of the members, while being rotated, to cause friction stir to weld the members. A small diameter projected part is disposed at a tip end of a shoulder of the welding tool, and is positioned out of a rotating axis of the welding tool. Especially, the method is suitable for spot welding and removes a surface oxidation film on a lapped welding interface to weld two members.
