                                                          A jeweler uses and hand held device to solder jewelry pieces together. You can buy a kit and do this at home yourself.  Just be very careful because it is combustible and the  equipment gets hot. Heat is applied to jewelry to allow the metal to flow and bond together. The jewelry melts and run together.
