Abstract A superplastic diffusion connection process includes the basic steps of: laser treatment of the surface to be welded of the pre-connecting alloy and the superplastic connection of the treated surface. The said preconnecting alloy is a high-temperature alloy. The present invention combines laser surface crystalline fining technology and superplastic duffision connecting technology ingeniously and realizes the superplastic duffision connection without altering the dase texture and property of alloy. The technology of the present invention can form high-quality alloy in short time and high production efficiency.
