The main methods of material joining include bolted connection, riveting, welding and bonding. Although technologies such as bolted connection can achieve rapid joining, they will cause damage to materials due to drilling holes in material components or local heating, and stress concentration cannot be avoided during use. In contrast, bonding technology is a non-destructive joining technology. Moreover, since the bonding interface bears the load as a whole, it improves the load-bearing capacity and extends the service life.
