A plating layer 4 is formed on a surface of a battery cover 3, and a peripheral edge part 37b of a cover case 37 is arranged on an upper surface of the plating layer 4. A welding part 40 is formed at a tip part of the peripheral edge part 37b. The welding part 40 includes a melted part 41 in which the tip of the peripheral edge part 37b is melted, and an elution part 42 flowing from the tip onto the plating layer 4, and the melted part 41 and the elution part 42 are welded to the plating layer 4 in the upper surface of the plating layer 4.

A resistance welding structure and a resistance welding method may form a highly reliable welded part by applying a proper pressurizing force and a proper heat value to a joining portion. Also provided are a member to be welded which is suitable for carrying out these resistance welding structure and resistance welding method, and a method of manufacturing the member to be welded. A member to be welded is formed with a recessed portion on one surface of a raw material formed of a metal plate, and a projection is formed on a back surface of the recessed portion. Assuming a plate thickness of the raw material in the inside of the recessed portion and around the periphery of the projection as D2, and a plate thickness of the raw material outside the recessed portion 2 as D3, the plate thicknesses of the respective portions have the relationship of D2

A convex portion which inclines in the direction of the short side is created by press work along the direction of the short side of a terminal, which extends longitudinally, from one end to the other end, and another terminal is pressed onto the convex portion with pressure and bonded together by electric resistance welding. At this time, because the convex portion inclines in the direction of the short side, the convex portion is not deformed and crushed; consequently, it is possible to ensure the area of the contact at which terminals are bonded together.

[Object]In a laser beam welding structure for welding workpieces by emitting laser beam onto a work portion of the workpieces, the size of the workpiece and resin member can be minimized and, when welding workpieces by emitting laser beam onto the work portion of the workpieces, burning of the resin member covering the workpiece and located near the work portion, due to the reflected laser beam caused from surface of a melting portion of the workpiece on the working portion can be prevented. [Means for Achieving the Object]In a laser beam welding structure for welding two workpieces 1, 2 by emitting laser beam 4 onto a the work portion between the two workpieces, wherein resin members covering the workpieces 1, 2 are provided at the position receiving the reflected laser beam from surface of a melting portion 6A on the working portion 6 when emitting laser beam 4 onto the work portion 6, resin members 5a, 5b capable of transmission of the reflected laser beam are employed for the resin member 5 located at the position receiving the reflected laser beam 3 so as to absorb the reflected laser beam 3 from surface of the melting portion 6A when emitting laser beam 4 onto the work portion 6 between the two workpieces 1, 2 and to prevent burning of the resin member 5.

An objection of the present invention is to provide a fuel injection valve with a reduced variation in an injection amount and, in order to achieve this object, a method for adjusting stroke, the method being able to correct change in an amount of stroke caused by welding. In the method for adjusting the amount of stroke of a movable member of a fuel injection valve including a nozzle member having a seat face, a nozzle holder member to which the nozzle member is joined by welding, and the movable member having a valve seat portion for coming in contact with the seat face, the amount of stroke of the movable member is adjusted by plastically deforming a deformable portion provided to the nozzle holder member after joining the nozzle member and the nozzle holder member by welding.
