Hub wrote this for the description of how it is done. First the frame is cut into two pieces and approximately one half inch is removed from the lower portion of the grip. The cutting is done in a wire EDM to assure straight clean cuts. The frame parts are then joined together and TIG welded with a copper mandrel holding the two pieces on the inside. The copper mandrel also helps control the welding heat by acting as a heat-sink. When welding the tool steel which firearms are made from, the metal has to be protected from excessive heat, or hard spots will develop showing up as the dreaded plum-color when blued.
