A welding method comprises disposing an aluminum-containing workpiece in a region irradiated with laser light, irradiating the workpiece with the laser light, and melting the workpiece at the irradiated portion to perform welding. The laser light is composed of a main beam and a plurality of auxiliary beams, wherein the plurality of auxiliary beams are positioned so as to surround an outer periphery of the main beam. This welding device is provided with a laser device and an optical head for irradiating an aluminum-containing workpiece with laser light outputted from the laser device and melting the workpiece at the irradiated portion to perform welding. The laser light with which the workpiece is irradiated is composed of a main beam and a plurality of auxiliary beams. The plurality of auxiliary beams are positioned so as to surround an outer periphery of the main beam. 在一种焊接方法中，将含有铝的加工对象配置于被激光照射的区域，使所述激光朝向所述加工对象照射，并使所述加工对象的被照射的部分熔融而进行焊接，所述激光包括主光束和多个副光束，所述多个副光束以包围所述主光束的外周的方式设置。焊接装置具备：激光装置；以及光学头，其将从所述激光装置输出的激
