Super-adhesive as substitute to welding?

I was watching Mythbusters the other day, and they used this 'super-adhesive' as they call it to hoist 650lb of weight from a forklift just by using one drop of the stuff (http://www.discovery.com/tv-shows/my...per-sticky.htm) and later on in the episode they use several drops to hoist an entire car pretty comfortably

Would this be a valid way to attach together metals in the absence of being able to weld? May not be as cost efficient, but could be useful for things like Hardox maybe that are weakened by heating them up to weld them together.

I do recall I've seen people mention that they've glued drive mechanisms to baseplates, but obviously they aren't in direct line of fire from weaponry and the like...

I'm fairly sure I already know the answer to this one, but I thought I'd be better asking people who know what they're doing, because I am clearly not one of those people hahaha

I know which episode you're referring too and it does pose a possibility.

But I'm less than convinced it will stand up to impacts as well as a weld would do.

Someone should try I guess, but it won't be me

That was the main concern I had really, they show it can take ridiculous loads but the tensile strength's never really gone into. Though that said, if it takes 650lb and if there's a way to use, say 10 drops of the stuff that's a theoretical 6500lb of strength in a join which sounds good to me...
I don't think it'll be as good as welding, personally, but if it's close it might be a viable substitute for those of us who can't weld, I guess!

Or, failing that, it might find some nice usage in the beetleweights...

The trouble with super glue is that it is quite brittle and doesn't like flexing (as in that failed tow truck myth) and it doesn't seem to do well with sheer (sideways) forces. On the other hand, Loctite is super glue with additives, so most bots have super glue in them. I have great results with epoxy on smaller internal parts as its more flexible and shock resistant.

HDPE refuses to be glued.

That's another good point - many plastics don't glue well. 3M makes DP8010 epoxy for hard to glue plastics, but its still not that great. For those who can't weld, the best bet for joining metal frames together is to make friends with someone who can :)

a case of beer goes a long way

or having a neighbour who owns a metal shop
