You may think it sounds crazy, but you can definitely weld precious metals like gold, silver, and platinum. Gold can be soldered (welded at a temperature below 840 degrees Fahrenheit) or brazed (welded at a temperature above 840 degrees Fahrenheit), and I recommend doing so with a gas torch — check out Chapter 13 for more on brazing and soldering. The same goes for silver. Platinum is a little different; oxyfuel (see Chapter 11) and tig are your best bets when welding platinum. Oh, and you may want to be sure you have a good lock on your welding shop before you start welding metals that cost thousands of dollars per ounce!
