There are several methods for joining metal to metal using heat:
Brazing and soldering are used to join two pieces of metal without melting them, by melting a different metal with a lower melting point, and letting it flow between the pieces as a joint. (Brazing is generally done at a higher temperature than soldering.) A person who does this could be called a solderer or a brazer, (but this is not a common term).
Welding is used to join two pieces of metal by melting them at the join and sometimes an additional filler piece is added. A person who does this is called a welder.

aluminum and copper
its a plumber
post heating : after completion of weld is not cool below to preheat or room temp. further it is heat by applying addition heating system to certain period of time and temperature to evalute hydrogen from weld metal.
A buttweld is a junction welded by heating two ends of metal with a weld plate and joining them under a specific pressure.

Mercury oxide.
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements
call of duty 2 pones metal gear solid by way theres online on call of duty its more realistic and better graphics and serriouslly nuclear bombs can kill a person in a snap so no graphics at all this why call of duty pones metal gear solid
No. Potassium metal is to reactive and expensive for everyday use.
The Metal hydroxides are strong base, therefore metal hydroxide decomposes on heating to form metal oxide and water.
after heating a compound named iron sulphide is formed which is a non-metal
metal melts on heating because it gets hot
