Abstract: A device and method for butt-welding metal strips using a laser is disclosed. The present invention utilizes clamping bridges to selectively grip the metal strips to be welded together. The ends of the metal strips are first prepared for welding by severing the ends using a movable laser. After the prepared strip ends are moved into butt-welding relationship, the same laser is used to weld the two strips together. Where the strips are of differing width, the laser may be rotated and its height above the strips adjusted in order to achieve the proper welding angle. Where one strip is continuously moving, a buffer facility is provided for selectively storing a portion of the continuously moving strip prior to cutting and welding. Through adjustment of the buffer facility, the clamped portion of the continuously moving strip, i.e. the trailing portion, remains stationary during cutting and welding while the leading portion of the strip continues to advance. Such a buffer facility might be used where the strip is undergoing a continuous process, such as the application of coating, downstream from the welding.

Abstract translation: 公开了一种使用激光对接金属条的装置和方法。 本发明利用夹紧桥来选择性地夹持待焊接在一起的金属条。 金属带的端部首先通过使用可移动的激光器切断端部来准备焊接。 将准备的带材端部移动到对接焊接关系后，使用相同的激光器将两个条带焊接在一起。 在条具有不同宽度的情况下，可以旋转激光器并且调整其高于条带的高度以实现适当的焊接角度。 在一条连续移动的情况下，提供缓冲设备，用于在切割和焊接之前选择性地存储连续移动的条的一部分。 通过缓冲设备的调整，连续移动的条带即后端部分的夹紧部分在切割和焊接期间保持静止，同时带的前端部分继续前进。 这种缓冲设施可以用于条带经历连续过程，例如在焊接下游施加涂层。
