Always apply solder to one side of the joint, and then pull the
solder through the joint by heating from the other side. If you
apply solder all around the joint, a weak joint may result from the
solder only flowing at the surface and not completely through the
joint. This is referred to as a “cold solder joint”. It is
particularly important to watch for this when soldering thicker
prices of metal together, such as heavy men’s ring shanks.
