摘要

PPROBLEM TO BE SOLVED: To provide a welding method of a forming raw material, which improves a ductibility of a portion welded in advance of a high-strength steel plate as a target workpiece, and then enhances a forming limit, and also to provide and a laser welding apparatus, a forming raw material obtained by the method, and a forming method and a formed article by using the forming raw material. PSOLUTION: A plurality of high-strength plates are overlapped or butted with each other, and are welded. Then, only the welded portion is locally reheated, or the second welding is applied to the vicinity of the first welding. It is preferable that the reheating or the second welding is made by using a laser or a laser welding. This method is preferably applied with the laser welding apparatus of the present invention. The forming raw material obtained by the welding method is improved in a forming limit, and is formed without a breakage, even in the case where a welding part would be broken during forming with a forming method using a conventional forming raw material. A formed article manufactured with the forming method using the forming raw material has an increased toughness in its welded portion. PCOPYRIGHT: (C)2009,JPO&INPIT

要解决的问题：提供一种成型原料的焊接方法，该方法提高了作为目标工件的高强度钢板之前被焊接的部分的延展性，然后提高了成型极限，并且本发明提供一种激光焊接装置，通过该方法得到的成型原料，以及使用该成型原料的成型方法和成型品。

解决方案：多个高强度板相互重叠或对接，然后焊接。然后，仅对焊接部分进行局部再加热，或者将第二焊接应用于第一焊接的附近。优选通过使用激光或激光焊接进行再加热或第二焊接。该方法优选地应用于本发明的激光焊接设备。通过焊接方法获得的成型原料的成型极限得到改善，并且即使在使用常规成型原料的成型方法在成型过程中焊接部破裂的情况下，也不会破裂而成型。通过使用成形原料的成形方法制造的成形品的焊接部的韧性提高。
