る不都合があった。As an example, a fuel tank for an automobile is constructed by welding upper and lower tank members made of thin steel plates, which are divided into upper and lower parts and press-formed into a dish shape, and watertightly welded at the respective peripheral flanges. If a high-energy welding beam such as a laser beam or an electron beam is used to weld the peripheral flange, the welding speed is significantly faster than conventional seam welding, effectively reducing manufacturing costs. can do. However, when welding is performed using a laser beam or the like, if the flank surfaces to be welded are not brought into sufficient contact, holes will be formed and weld defects will occur. Therefore, conventionally, upper rollers for pressure are placed on both sides of the welding beam with respect to the traveling direction of the beam, and a lower roller that cooperates with the upper rollers is also placed below the flange surface to be welded. , was doing welding. For this reason, the flange width required for welding work (the flange dimension in the direction perpendicular to the advancing direction of the welding beam) increases, the weight of the fuel tank, etc. increases accordingly, and the installation space is also increased. There were increasing inconveniences.

The gist of the present invention is a thin plate flange welding device characterized by being provided with rollers. According to the present invention, the forward direction of the welding beam in the traveling direction;
Preferably, pressure rollers are provided at both the front and rear, and beam welding is performed while applying pressure to the thin plate flanges to be welded by the rollers to bring them into close contact, so welding can be performed at high speed without causing welding defects. In addition, the flange width in the direction perpendicular to the direction of travel of the welding beam can be made smaller than before, which has the advantage of reducing the weight of products such as fuel tanks and at the same time reducing the installation space. . Furthermore, in a preferred embodiment of the present invention, the pressure roller is supported so as to be rotatable around an axis perpendicular to the axis of the navel, so that it can smoothly and easily press curved portions at the four corners of a fuel tank, etc. It can be welded.
