Question
What is the first question when choosing a joint?
Answer
Does it ever need to come apart? Temporary joints allow repair, upgrade and recycling; permanent ones are stronger, lighter, sealed and cheaper to assemble.
Question
When is adhering the right choice?
Answer
For dissimilar materials that cannot be welded, thin sheets a rivet would tear, and joints that must be sealed — because load is spread over the bonded area rather than at points.
Question
What does welding cost?
Answer
Compatible materials only, heat that distorts and weakens the area around the joint, skill or a robot, and no way to reverse it.
Question
What is the end-of-life consequence of a glued product?
Answer
It is one object that can only be shredded. A screwed product is a pile of materials that can be separated and sorted.
