Default Odd behaviour of brazed joint

wrote:

Silver-soldered to be precise.

One of the bars of the stainless steel BBQ grill detached itself at
one end from the stringer (I hope I am making myself clear, not too
sure about the correct terminology). The spot weld simply gave way.

I silver-soldered it back into place using Extra-Easy. On first
inspection a good joint, could not force it apart.

After several BBQ uses during which the grill is subjected to far less
stress than when I was testing the joint, the latter gave way.

You probably simply melted the solder.

Hope This Helps!
