Choosing and Using Structural Adhesives

Adhesives content from Machine Design: There are several reasons why structural adhesives are chosen for a wide variety of assembly operations. Unlike mechanical fasteners, they don't damage substrates by needing drilled holes, and there's no heat distortion (a risk with welding). They can also join dissimilar materials without galvanic corrosion, work with different geometries, and don't concentrate stress at a few localized spots, thus increasing fatigue resistance. And after the joining processes, structural adhesives don't require refinishing steps or leave protrusions, so they are aesthetically more pleasing.
