There are several kinds of welding that can be used to participate materials together. I’m going to be speaking 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 referred to as stick welding
Tig welding –
Wire feed welding is additionally known as MIG welding. The correct term is GMAW or Gas Metal Arc Welding. When you use this welding technique you have a torch or gun inside your hand and squeeze a trigger. When you squeeze the trigger, wire in the torch will begin to turn out. This wire is then pointed at what you need to weld.
The technical term for arc welding is SMAW or MMAW. This is Shielded or Manual Metal Arc Welding. This time around you utilize an electrode which is only a duration of filler wire which is an average of about 1 foot long and is also covered inside a flux. While you make use of the rod the flux will burn off and make a shielding gas that protects the weld.
Tig welding is an extremely fine and delicate welding technique. For this you’ll want to hold you torch in a single hand and employ a filler rod from the other. The theory is you slowly feed the filler rod into the weld along the way. You’ll be able to weld with TIG or GTAW, Gas Tungsten Arc Welding without the need for the filler rod and simply just melt both pieces of metal together. This is whats called "fusing", where while using the heat from arc you melt and fuse it together.
As well as the last different form of welding that you have is termed "spot welding". This can be employed for sheet metal fabrications. In a nut shell both the items of metal that need to be joined are placed between the electrodes about the ends from the arms in the unit. They come together and the welded part will probably be between those points. It is only often a second roughly for this to happen. Merely a buzz and it is done. This can be a very fast method of joining sheet metal parts. Such things as toolboxes are a good instance of exactly what do be and so are spot welded.
There are also a number of other different types of welding systems for metal like friction, ultrasonic, thermite and sub arc only to name a few.
But undoubtedly those stated earlier will be the most common today.
