【 摘 要 】

Metal and composite bonding structures are widely used in many industrial fields. But in the material production and processing and bond- ing process, the adhered surface is not clean, is between the two surface bonding with adhesive is not strict, the existence of gas, dust and other rea- sons, the adhesive structure foaming, deboning, bonding strength decrease- e, durability and reliability reduce etc. In this paper, a kind of typical metal and composite bonding structure was studied by electromagnetic ultrasonic testing. The results show that the results are obvious. The electromagnetic ultrasonic can be used to test the adhesion of metal and composite materials.
