I think you may be associating “glue” (or epoxy in this case) with an inferior type of fastener. Modern glues chemically bond the materials, forming a much stronger adhesive than physical fasteners ever could.

If anyone would like a simple demonstration of just how good modern adhesives are, go buy a decent wood glue (not even an epoxy!), some wood, and test the strength of some glued joints. With the exception of butt joints (flat edge to flat edge), 99% of the time the wood around the joint will break before the joint itself. With a quality glue or epoxy, even butt joints can be stronger than the parts they glue together.

In some situations, industrial grade structural adhesives can even be stronger than well made welded joints, which is literally just heating up the metal so it can recrystallize into a single lattice.
