Several Categories of Welding
There are several kinds of welding that can be used to join materials together. I'm going to be speaking about the welding of metal to metal and steel to steel.
The commonest forms welding are:
Wire feed welding - which many people call mig, mag, gasless or flux cored.
Arc welding - often known as stick welding
Tig welding -
Wire feed welding is also known as MIG welding. The right term is GMAW or Gas Metal Arc Welding. When using this welding technique you possess a torch or gun inside your hand and squeeze a trigger. Once you squeeze the trigger, wire in the torch are going to turn out. This wire might be pointed at what you look for to weld.
The technical name for arc welding is SMAW or MMAW. That is Shielded or Manual Metal Arc Welding. This time around you use an electrode that's simply a duration of filler wire that is an average of about 1 foot long and it is covered in a flux. Because you utilize rod inside the flux will melt away and develop a shielding gas that protects the weld.
Tig welding is an extremely fine and delicate welding technique. With this you have to hold you torch in a single hand and make use of a filler rod from the other. The concept is basically that you slowly feed the filler rod into the weld as you go. You can weld with TIG or GTAW, Gas Tungsten Arc Welding without resorting to the filler rod and just melt both the pieces of metal together. This is called "fusing", where using the heat from arc you melt and fuse it together.
As well as the last different form of welding which you have is called "spot welding". This can be used for sheet metal fabrications. As a brief explanation the 2 components of metal that ought to be joined are positioned between the electrodes on the ends with the arms in the unit. They are offered together along with the welded part will probably be between those points. It is only normally a second roughly to do this. Simply a buzz and done. This can be a very quickly means of joining sheet metal parts. Such things as toolboxes are a good demonstration of exactly what can be and are spot welded.
There are also all kinds of other various kinds of welding methods for metal like friction, ultrasonic, thermite and sub arc just to name just a few.
But undoubtedly the ones mentioned previously are the most popular today.
