Glueing metal to metal successfully

You can solder metal to metal, but the quickest and easiest way to join metals is by using a strong glue. The surface needs to be clean, and the right glue must be applied. To make sure the adhesive will stick, you need to get rid of any dirt or dust on the surfaces by confirming they are sanded and cleaned thoroughly. You may want to wear gloves because if you touch the bonding surface with your hands, the oil from your skin will rub on to the surface and affect the glue. If you use sandpaper with a fine grit, this will add texture to the two surfaces and make it easier for them to stick together.
