The compound, magnesium fluoride, is used in the process of brazing. It helps to smooth out the air particles by using this chemical compound to get rid of the pollutants, which helps with preventing oxide formation.
The process is dehydration+synthesis.
Cementation
That process is called cementation.

Brazing is actually not a method of welding as it does not melt the joint metal together. Brazing is actually much closer to soldering. It is a process that (usually) uses a gas torch and a thin brass rod to bind two (or more) pieces of metal together. The torch heats the joints surface to the melting temperature of brass at which time the brass filler rod is melted into the joint to fuse them together.

Brazing isn't welding - it's more like soldering. You use a rod made out of brass for the process of brazing.

Brazing is a process used to join two metal pieces together The filler metal used for joining is heated above the melting point and poured over the base metals or pipes.
'Soldering' is the correct spelling for the joining process that uses a solder alloy whose melting temperature is less than 840 degrees Fahrenheit. +++ Soldering (including brazing) and welding are two totally different processes!
It's joining two pieces of metal together, either by adding a 3rd molten metal at the joint, or by melting the metals themselves until they fuse together. Do note that there are a few similar methods for joining metals called brazing and soldering. What's what is determined by which temperature the process is performed at.
brazing is joining of two metals by using filler metals.to melts the filler rods only which temperature is above the melting point (>450c).initially flux metal is used to avoid the oxidation ....this process is very strongly than soldering method ...weaker than welding method..
welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.
Yes you can but you might consier brazing (uses a brass filler rod) for the repair, it is a cooler repair process and can be stronger for this typr of repair.
