Solder does have mechanical strength, but it's not as strong as other
metals.  When connecting wires, you're supposed to provide some other
method for mechanical strength.  when soldering pipes, sheet metal etc.,
you're soldering sufficient area, to provide strength.
Common solder is very soft and easily broken.  As an experiment try
pulling on a piece of solder and see how easily it breaks.  Now try the
same with copper or steel wire of similar gauge, to see how much harder
it is to break them.
