Think of making a realist cartoon fursuit the only problem is the contruction.

I don't think I'd be of much help on such a costume. My experience relies more on performance than cosntruction for costumes. The only thing that I can offer is that adding small motors and servos to a costume headpiece will shift the weight around a bit, so be certain that you are comfortable with the weight of the electronics in addition to the costume if you're going to be active.

I hate to ding people for their language skills because I realize that for some people here, English is not their primary language. But it is almost impossible to tell what you are asking here. First, a few terms that may help to explain what you are trying to do:

Soldering: This is a process of joining two metals together using a different type of metal and a "flux" to clean the joint. This usually refers to joining copper based metals (copper, brass, bronze) together using lead/tin solder and a resin based flux. You can also join steel and iron using lead/tin solder and acid based flux. In both cases, the flux residue must be removed when finished. This process is usually done with a "soldering iron" to provide the heat, although a torch can be used. Soldering supplies can be purchased at Radio Shack and other electronic or plumbing supply places and hardware stores. Gold and silver (and a few other metals) can also be soldered, and there are also lead-free solders in use as well as "Silver Solder" which requires higher temperatures and is much stronger.

Brazing: This is also called "hard soldering" and usually involves joining steel or iron using a brass binder and a flux to clean the joint. Much higher temperatures are needed to do this, usually from a torch or an electric arc. You usually need to go to a welding supply house to find brazing supplies.

Welding: This is a process of joining two materials together using the same type of material and usually requires either a torch or electric arc for metals (plastics can be welded with hot air). Rather pricey equipment is usually required to do welding properly. Note: joining two pieces of brass using brass filler is welding brass, not brazing.

The soldering process almost always involves having an overlap area of the two materials with the "solder material" acting as a glue to hold them together and is fairly easy to learn to do properly. The mistake that most people make is that the pieces themselves must be hot enough to melt the solder when applied, do not melt the solder with the soldering iron and drip it onto the parts. Welding does not require an overlap to work, but the required skill level is higher. Search on the internet using these terms and you should be able to find tutorials on how to do these processes. Do not overlook gluing your project together, when properly done, glued joints are very durable!

As for the moving parts, you just need to be able to design these yourself or copy a design that somebody else has already done such as the ones on wolftronix that you pointed to. The taxidermy supplies can be purchased from VanDykes: VanDyketaxidermy In many cases, toys can be dismantled and moving parts from them adapted to your use, charity shops and thrift stores are good places to look for cheap toys to dismantle.
