Such a roll-formed product is formed into a closed cross-section by continuously forming it into a predetermined cross-sectional shape by roll-forming and then joining polymerization contact portions. As this joining method, as disclosed in Japanese Utility Model Laid-Open No. 63-184119, a method of brazing the overlapping contact portion over the entire length, or a method of spot welding at a pitch of about 100 mm is known. There is.

歪みを生じるなどの不都合があった。However, in the case of those joined by spot welding, although the second polar moment of area is good, there are some parts with low torsional rigidity due to the intermittent welded parts, There is an inconvenience such as distortion occurring in secondary processing such as bending.

が困難であるといった不都合があった。In addition, in the method of brazing over the entire length, since the brazing processing speed is relatively low, the conveying speed of the line is reduced, the forming tact is wasted, the manufacturing efficiency is reduced, and the brazing rod is also used. However, it is difficult to reduce the manufacturing cost, such as requiring replacement of the above.

It is to provide a low-cost roll-formed product having uniform rigidity over the entire length.

The present invention is achieved by providing a roll-formed product characterized by being continuously welded and joined over the entire length by continuous welding means installed in series in a roll-forming machine.
Moreover, it is preferable that the superposed contact portions are joined by seam welding. Alternatively, the overlapping contact portion may be joined by laser welding. Particularly, it is preferably used for a window frame of a vehicle.

In particular, if seam welding or laser welding is used, the welding speed can be improved, and thus it is possible to prevent the transport speed of the line from being lowered due to the rate control in the welding process.

As shown in FIG. 3 (a), first, the hoop material 10 made of one metal strip is formed into a predetermined cross-sectional shape through several sets of roll forming pieces 11. Next, the overlapping contact portion 4 is joined by so-called seam welding through a pair of upper and lower rotating electrodes 12 installed on the same line. As shown in FIG. 3B, the overlapping contact portion 4 is pressed against the rotating electrodes 12 from above and below while the rotating electrodes 12 are in contact with each other.
It is welded by resistance heat generated by a high-voltage current flowing between them. At this time, the superposition contact part 4 is continuously joined by continuously energizing both rotary electrodes 12 from the control device 14 via the transformer 13, and even if intermittent energization,
If the pitch of the current-carrying points is set small, the melted portions are formed to overlap each other, and the superposed contact portions 4 are continuously joined.

によれば、溶接速度及び溶接強度の調整が容易である。As is apparent from the above description, according to the roll-formed product of the present invention, it is possible to provide uniform and high rigidity over the entire length. For example, the torsional rigidity can be improved about 10 times as compared with the spot-welded one. Therefore, it is possible to prevent harmful deformation from occurring in the secondary processing, reduce the plate thickness, and reduce the manufacturing cost and the weight. This is particularly advantageous in vehicle window frames. Moreover, if seam welding or laser welding having a high welding speed is used, it is possible to avoid being rate-limited in the welding process, so that the manufacturing process can be made more efficient and the manufacturing cost can be further reduced. Especially by laser welding, the welding speed and the welding strength can be easily adjusted.
