The melting point of solder generally decreases as the tin content increases. This is because tin has a lower melting point than other common soldering materials, such as lead. An increase in tin typically leads to a more fluid and lower melting alloy, which can be beneficial for soldering applications. However, the exact melting point can also depend on the specific composition of the solder alloy.
Depends on the solder used. If silver solder is used it is actually stronger than the pipe itself.

Yes, graphite is more common than diamond.

You need more than one number to have a COMMON factor since common implies more than one.
yes
There is more than 15 instruments techniques. Some of the techniques would be blow in, blow out, spit, line up and have fingers in place.
No 12" RCP is more common than 15" RCP, 18" RCP is also more common than 15" RCP.
It is not a matter of style. The key is the application of the techniques. It is more the individual practitioner than it is the style.
A good amount of solder is less than one drop, and should be applied through a very hot and clean gun, also making sure that you are using a new solder wire, avoid using solder from already soldered components because it will be having no zinc chloride.
for a person with no experience it is still very easy to solder. but the steps still have to be known. For silver bead or rosin solder you need a soldering iron of about 20W. The iron takes a few minutes to heat. at higher powers the tip will become discolored. Obviously you should never touch the tip so to tell if it is hot just touch it on a VERY wet sponge, if it sizzles instantly it is hot enough. Melt a tiny bit of solder on the tip of the iron, this will eventually harden on the tip. this is called tinning. You tin the tip for a couple of reasons: It prevents the actual tip from rusting, the tinning, if it rusts will just sand off and more solder can be added. It also transfers heat more effectively You do not solder wires by the tip, you solder the joint between them. you can joint them by twisting them together (wires) or bending them in a loop (lugs) You do not need to solder screws unless they are really small heat the joint for a while with the tip and then press a long piece of solder on to the tip. remove it and wait for more heat/increase power if it does not melt within two seconds. coat the connection so that the melted solder flows around it similarly to a meniscus. Be sure to remove the solder before the iron or the solder will harden with the connection. Solder cools faster than you would think. Make sure you strip enough wire for the connection, do not skimp on this, the wire will heat enough to melt the insulation and then you will have a mess.
