On the one hand, it isn’t hard to make a solder pot. All you need is a container that won’t melt and a heat source. But it seems like molten metal should be in something a little harder to tip ...

Soldering is the joining of metals by melting a filler metal into the joint. Unlike in welding, only the filler metal — the solder — melts. The metals being joined usually have a much higher ...

Now none of that solder goes to waste. Using a torch, crucible, and being around liquid metal can be pretty dangerous, so just be careful as you go. Check out the guide below for a complete tutorial.

Twist the wire gently in your fingers until the wrap is tight, then seal the wire threads by melting a small amount of solder along the wire to “tin” them in place. This approach makes the ends of ...

Uniformity of capillary space will ensure good capillary flow of the molten-solder metal. Excessive joint clearance can lead ...

2) Heat the joint with a soldering iron or pencil from underneath. Apply solder to the top until molten solder wicks into the joint. Let this cool undisturbed to avoid a "cold" solder joint.

Instead it’s formed partly by the filler hooking into the tiny hills and valleys of the joint metal surfaces, but mainly from the solder dissolving (not melting) into a very shallow surface ...
