    摘要: A rolled steel plate 1 wound in a roll shape is unrolled and is cut in given dimensions to form a blank 2. In this case, a cut surface 2a is caused to incline at 1 to 3 degrees relative to the thickness direction of the blank 2, wherein the inclination direction of the cut surfaces 2a, 2a on each side is reversed. The blank 2 cut in this manner is roll-formed to cause the cut surfaces 2a, 2a to confront each other. Since the cut surfaces 2a, 2a on each side incline at 1 to 3 degrees in the opposite direction as described above, the cut surfaces 2a, 2a are caused to be parallel. Then, the confronting sections are laser-welded to form a cylindrical body 3.

    摘要: An exhaust muffler comprising an outer cylindrical body, front and rear end plates mounted on each end of the outer cylindrical body, porous plates fitted on the insides of the outer cylindrical body and each of the end plates, and partition plates for dividing the internal space of the outer cylindrical body into several chambers, wherein when joining the component parts with each other, three or four component parts are superposed via their joint portions each on the other and integrally joined by laser beam welding so as to obtain a reduction of welding steps and minimize the thermal influence in the manufacturing process while ensuring an air-tight condition of the partitioned chambers. When an exhaust pipe and tail pipe are connected to the end plates, respectively, they are laser beam welded to the end plates in a superposed fashion. Alternatively, the outer cylindrical body is formed in a multiple-layered construction with inner and outer panels which are so formed integral with each other as to squeeze or press inwardly, when assembling, an internally installed unit over its fill periphery, thereby not requiring particular measures for fixedly securing the internally installed unit to the outer cylindrical body. Preferably the outer cylindrical body and end plates are formed on an aluminum-plated or a stainless steel plate, thereby dispensing with a coating after welding.

    摘要: The invention relates to a laser beam welding method for carbon steels applied to laser beam welding of carbon steels of different carbon content, and in order to improve uniformity of fused metal in the welded region, a laser beam is applied obliquely to the joint region between the carbon steels from the side of the carbon steel having the lower carbon content. When manufacturing a vehicle wheel 1 by this method, the laser beam is applied obliquely from the side of the hub 3 of rolled steel plate which contains about 0.1% of carbon to the joint region with the boss 2 of carbon steel for machine structural use which contains about 2% of carbon so as to fuse the end of the hub 3 and cause it to penetrate into the welded region.
