In a vehicle to which the present joining structure of vehicle steel plates is applied, a third welded portion is set between a first welded portion and a second welded portion, wherein at the first welded portion, a pillar outer rear flange, an SM outer rear flange, a pillar inner rear flange are joined to one another; and at the second welded portion, the pillar outer rear flange and the pillar inner rear flange are joined to each other. At the third welded portion, the pillar outer rear flange and the SM outer rear flange are joined to each other. Accordingly, a tensile load F acting on the pillar outer rear flange is distributed toward the SM outer rear flange side.

Joining structure of vehicle steel plates and joining method for vehicle steel plates

A high viscosity material is discharged in the form of a continuous thread from an application nozzle toward an end of a workpiece and a space S on the side of the workpiece so that the high viscosity material in the form of the thread adheres to a front surface of the workpiece and the high viscosity material discharged in the form of the thread into the space on the side of the workpiece pivots around an edge of the workpiece to a back surface of the workpiece and adheres to the back surface of the workpiece. The high viscosity material can thus be applied to both the front and back surfaces of the workpiece in one step of discharging the high viscosity material only from the front surface side of the workpiece.

Method for applying high viscosity material on edge surfaces

A welding method for integrally welding three or more superposed metal plates includes a spot welding of joining the first vehicle body structure plate and the second vehicle body structure plate by spot welding in a plurality of places along an opening edge of the door opening portion in a state where each of the metal plates is superposed, and a laser welding of joining the surface plate and the first vehicle body structure plate in a plurality of places including a place between welding places of the spot welding after the spot welding. The joining being performed by emitting laser light to the surface plate and by scanning the laser light to stir a molten pool including a molten metal of the surface plate and the first vehicle body structure plate melted by the laser light.
