By laser joining using a member with a complicated surface shape as the aluminum alloy member, a composite is obtained having increased bonding strength with the resin member. After forming asperities by etching treatment on the surface of the aluminum alloy member to be joined, one surface of said aluminum alloy member is placed on the resin member, and then a laser is irradiated onto the other surface of said aluminum alloy member, softening the resin member contacting the aluminum alloy member and filling the aforementioned asperities with said resin. Blasting may be optionally performed before etching.

The invention relates to a method for modifying the geometry of gear wheel tooth flanks using a tool having a toothing that engages with the gear wheel (ZR) during precision machining. In this case, a profile that varies over the width (Bw) of the tool (1) is produced on the tool (1) in that, during a dressing operation, a dressing wheel (3) is moved along the tooth flank (5) of the tooth (6) to be dressed.
