While solder can be used for joining metal, metal working solder is different from electronics solder (greater strength and hardness, usually higher melting point, may be acid core). Both can usually be melted by a soldering iron, but I wouldn't consider a soldering iron to be a very useful tool when working completely in metal.

Soldering irons are generally intended to produce just enough heat at a concentrated point so as not to damage electronic components, and if you are working with a solid piece of metal, even a fairly small piece, it will not be able to produce enough heat fast enough.

is possible because the wires for the components are small and won't dissipate heat too fast like a small metal sheet or solid piece of metal would.

A pencil torch is what I use for small things that require more heat. I have one very similar to the one in the picture - paid less than $15 for it and it works well.

Anyway, could you be more specific about what type of metal sculpture you are interested in?
