That is really a trick to accomplish. Use of some sort of heat sink would be necessary to keep the heat from melting the original solder on the barrel.

There was a local doctor that invented a set of forceps that had a channel attached to the forceps that had to be welded to the forceps. A local welder was doing it under water with some sort of advanced technology of the day and that was over 20 years ago. Somehow these things get done and they aren't a mystery to the person doing the job...
