A method for laser welding of non-transmissive composite materials includes: forming an energy channel having an end opening and extending through a first part made of a first material; and welding asecond part made of a second material to the first part via laser heating of the materials of the first and second parts proximate to the end opening of the energy channel such that the materials of the first and second parts fuse to form a weld nugget, attaching the first part to the second part. 种非透射性复合材料的激光焊接方法，其包括：形成能量通道，该能量通道具有端部开口并且延伸通过由第材料制成的第部件；以及经由对第和第二部件的靠近于能量通道的端部开口的材料进行激光加热来将由第二材料制成的第二部件焊接于第部件，以使得第和第二部件的材料熔合以形成焊接熔核，从而将第部件附连于第二部件。
