The broken clamp failed on the bit that is folded back on its self and is then crimped into the overlapping part, the crimped bit became very un crimped! I was thinking about popping a rivet through to stop the crimp from taking all the strain.
It's not crimped, that's for hair and pastry
It's spot welded.
Pressure is applied through electrodes either side and while clamped together an electric current is passed through both layers of metal, with heat up and weld to each other.
The more spot welds the stronger.
it's used extensively on car bodies.
When you see films of robot assembly units sparking away that's what they're doing.
It's not falling off, it's an upgrade opportunity.
That's another thing I have had happen when overightening clamps. Admittedly the cheaper kind, but the round dowel type piece, I have crushed from overtightening. If a clamp is broken, best to just buy new ones, they are cheap enough. I suppose you could rivet it but it will always be a weak point.
