The application of solder wire during the jointing process is typically required for integral ring fittings or capillary fittings, as these types of fittings use soldering as the method to create a secure connection between the pipes or components. Type A or Type B fittings usually do not require soldering for jointing.
This is known as solder bridging, where an unintended connection forms between two conductive paths due to excess solder. It can cause short circuits and impact device functionality. Preventing solder bridging involves using the correct amount of solder and properly inspecting and cleaning the solder joints after soldering.
It could be either. Any type of liquid core solder (acid core, rosin core, etc.) is heterogenous, since there's the metal part and the core part. A solid-core solder is probably homogeneous.
Flux cleans the metal and helps the solder stick.
No, pure brass is difficult to solder with plumbing solder because it has a high melting point and poor wettability with typical lead-based solders. It is recommended to use an appropriate flux and solder with a higher silver content for better adhesion and conductivity when soldering pure brass.
It is probably referring to the type of fitting. A fitting that is soldered to a copper pipe. It is called sweating when you use solder and a torch to connect copper pipe together or attach fittings to copper pipe.
The term "sweating" in plumbing refers to the process of joining and sealing copper pipes and fittings by heating the copper and applying solder after the pipes/joint fitting have been properly cleaned and flux applied.

Take either an SOS pad or a wire brush and rough up both the inside of the brass fitting and outside of copper pipe, put the copper pipe into the fitting and solder around it.
Clean the end of the pipe and whatever kind of fitting you are putting on it with either steel wool or fine sandpaper. Put flux on both pieces covering all the surface where they will be joined. Use a propane torch and heat on one side of the fitting and touch the solder on the opposite side. When the solder gets hot enough to melt, it will be drawn to the heat source. By having the solder on the opposite side from the heat you know there is solder completely around the fitting. Let it cool before handling.
Any "LEAD FREE"
To properly solder a copper pipe, first clean the pipe and fitting with emery cloth. Apply flux to both the pipe and fitting, then heat the joint with a propane torch. Once the joint is hot enough, touch the solder to the joint and let it flow around the connection. Allow the joint to cool and wipe away any excess solder.
Any solder / brazing alloy that is LEAD FREE according to the safe water drinking act of 1974
You can use a paste flux and heat (as from a soldering gun) to reattach the solder.
The solder will most likely melt at the operating temperature of the heater.
First, clean the inside of the fitting to be soldered, and the outside of the tube it is to be soldered to, with abrasive cloth, steel brushes, steel wool or equivilent. Second, apply a thin coating of soldering flux to these surfaces. Install the fitting on the piece of tubing and turn to be assured of a coating of flux is spread evenly between these surfaces. Using a torch apply heat to the base of the cup of the fitting. Using a circular motion apply heat evenly all around the fitting (at its base). When flux begins to show signs of bubbling apply appropriate wire solder at top of fitting cup. If joint is sufficiently heated solder will become liquidious and run into the joint. Apply only enough heat to melt soldering compound being used. When solder becomes liquidious remove heat from joint. Allow joint to cool and solder to return to solidus state. Overheating will cause flux to burn inside joint. The carbon formed will prevent solder from filling that area. If several of these "areas" join together, not only will the joint be weak but it will also leak!
