Claim 7:
8. A method of processing a composite material structure, the method comprising:
providing the composite material structure, the composite material structure comprises a first metal member and a second metal member bonded together, wherein a bonding surface is formed between the first metal member and the second metal member, a material of the first metal member is different from a material of the second metal member, the second metal member comprises a main body;
drilling a first hole through the first metal member so that one end of the first hole reaches the bonding surface, a circular bonding line is formed in the bonding surface adjacent to the one end of the first hole, and the circular bonding line is exposed from the first hole; and
