Technical Tips – Joint Design

There are three basic joint types; co-axial, lap and butt joints.

Anaerobic adhesives are usually most suitable for co-axial type joints (where one part slots into another) or for threaded parts. Whether or not the joint needs to be dismantled will determine the strength of adhesive to use.

It is vital to consider joint configuration in the early stages of your product design to achieve maximum performance. Joints that have originally been designed to be welded may need to be redesigned to obtain optimum performance with adhesives. The engineer also needs to consider the loading of these joints and where the forces occur.
