There are several categories of welding that can be used to join materials together. I will be talking about the welding of metal to metal and steel to steel.
The most frequent forms welding are:
Wire feed welding – which a lot of people call mig, mag, gasless or flux cored.
Arc welding – also called stick welding
Tig welding –
Wire feed welding can also be called MIG welding. The appropriate term is GMAW or Gas Metal Arc Welding. When using this welding technique you possess a torch or gun within your hand and squeeze a trigger. When you squeeze the trigger, wire in the torch will begin to emerge. This wire is then pointed at what you need to weld.
The technical reputation for arc welding is SMAW or MMAW. That is Shielded or Manual Metal Arc Welding. This time you employ an electrode which can be only a period of filler wire that’s an average of about 1 foot long and is covered within a flux. When you use the rod in the flux will burn off and create a shielding gas that protects the weld.
Tig welding is certainly a fine and delicate welding technique. With this you should hold you torch in one hand and use a filler rod within the other. The idea is basically that you slowly feed the filler rod into the weld along the way. You can weld with TIG or GTAW, Gas Tungsten Arc Welding without using the filler rod and just just melt the two bits of metal together. This is known as "fusing", where using the heat from arc you melt and fuse it together.
And also the last different type of welding that you’ve is called "spot welding". This can be employed for sheet metal fabrications. As a brief explanation both bits of metal that need to be joined are positioned between the electrodes about the ends from the arms of the unit. They are offered together and also the welded part will probably be between those points. It is just often a second roughly to do this. Just a buzz and done. This is a very quickly way of joining sheet metal parts. Things such as toolboxes make the perfect demonstration of what can be and so are spot welded.
Additionally, there are a great many other a variety of welding methods for metal like friction, ultrasonic, thermite and sub arc only to mention a few.
But by far the ones stated previously are the most frequent today.
