Is anybody familiar with "gluing" on patch panels?

If gluing panels was so great, everyone would be doing it instead of welding them, unless of course welding is a dying art and it's only a matter of time before everyone converts over to glue, but I doubt it.

Actually, thats what I've been reading in quite a few articles. I just bought a new welder, and it's not that I'm against welding, I'm looking forward to it; but I'm a novice, and don't want to warp the panels from using too much heat.
