You can do it but you have to be VERY careful for silver solder a very large 100w+ gun may be needed you CANNOT overheat the batteries or they WILL explode or be made useless.
Solder is a metal alloy that is fusible. The kind typically used in electrical soldering melts at 370 degrees Fahrenheit, which is equivalent to 188 degrees Celsius.
A soldering iron should work if it is able to get hot enough and you have the right kind of solder. You need a solder that is made for electetonics. If you have an acid core or one used for plumbing they will not work. The iron will need to produce enough heat to get the item soldered hot enough for the solder to flow and bond.
In reflow soldering, the solder is applied as a 'solder paste' typically by using a stencil mask and a squeege. The solder paste contains both a solder flux and the solder in the form of minute solder balls. The solder paste operation is done BEFOREadding the components to the board. The board is then passed through a reflow oven at which time, the solder paste melts to complete the soldering of the components to the circuit board. The reflow oven will have several heating zones designed to preheat, activate the flux, reflow the solder, and cool the board. The oven is setup so the components receive as little thermal shock as possible, and spend only a few seconds above the solder melting temperature.In wave soldering, the components are placed on the board. THEN the board is placed in the wave soldering machine. Typically the first step in the wave solder, the bottom of the board passes through a fluxing operation which either sprays flux on the bottom or passes the bottom of the board through a flux foam. After the flux, the board will usually pass a pre-heater to activite the flux and pre-heat the board for the soldering. Then, the bottom of the board is passed through a molten solder wave (looks like a smooth waterfall only consisting of molten solder). Afterwards, there will be a stage of cool-down.Some details of the process vary by how expensive the oven or wave-solder machine is, the complexity of the circuit board involved, for what kind of volume the production line is intended for, and how 'mil or space qualified' the circuit board is.

Depends on the kind of solder.
There are three classes of problems. First is the health hazards from soldering fumes. At one time, solder contained lead. Heat lead enough to melt it and it generates fumes that are dangerous. The rosin flux in solder also produces hazardous fumes. Proper ventilation will overcome this. The second is done through the use of corded handheld soldering tools, which have static electricity at their tips that can damage components. If you use corded soldering irons, get the kind with grounded tips. These ones have three-prong plugs. The third is thermal damage to parts. Using solders with low melting points, and proper technique, will solve this.
Usually an alloy of tin/lead - though there are others (silver for example, used in repairing jewellery)
When you use a soldering iron you would be soldering some kind of metal frame or something because soldering irons are irrelevant to soldering iron. Sorry, not applicable.

You can solder copper very effectively. However, there are so many better ways now, i virtually never solder. In this case I generally cut out the bad piece of copper and fit PEX between two Sharkbites or compression couplings. Many of the buildings I work in are built of very dry old wood so soldering is not ideal.

A soldering iron kit includes a soldering iron, a soldering iron stand, a sponge, diagonal cutters, long nose pliers as well as wire strippers. This example aplies only to sets for beginners.
