What are the different types of welding and what are they for? If you are looking for 20,000 foot view of the different types of welding, using, stick around for a minute, I think I can help.
Stick welding
Stick welding is often referred to arc welding, although it's kind of a misnomer, because the TIG welding and MIG welding are actually arc welding too. However, for arc welding is what most people still call it a stick welding. Stick welding is an old school type of welding that Grandpa used to do to fix his tractor in a barn. using rod electrodes 6013, 6011 or 7018 welding rod that was chucked in the electrode holder, which looks a bit like a battery jumper cable clamps. the rod is struck like a match to go bow, a rod is fed into a pool because it burns. Stick welding is a pretty simple machine and welding rod is too easy and also pretty cheap. You can buy a Lincoln 225 AC welding machine at any Home Depot for a time less than $ 300.
MIG welding
MIG welding is considered one of the easiest types of welding to learn. Why? Since the rod does not have to be fed, such as shortening the welding rod. wire is fed through a cable and out the end of the MIG welding gun and all the operator is required to do is pull the trigger and weld. Sounds simple does not it? So it's not so simple. It's a little easier to teach than to keep welding, but only slightly.
MIG welding is actually kind of describes the 2 types of welding ... bare wire MIG, and flux core welding.
bare wire MIG is cleaner, and will weld thin metal, but the core flow is easier to use outdoors and does not require MIG welding gas cylinder or flow meter. Flux core welding is usually used to be a cheap hobby welder and where the buyer does not want to spend money for gas and gas conversion kit, or for really heavy-duty applications such as earth moving equipment for the production of heavy welding.
TIG welding
TIG welding is considered one of the more difficult types of welding to learn ... harder to master than MIG or stick welding. This is because both hands are needed for TIG welding. With one hand holding a TIG torch with tungsten electrodes that provides the onions and heat ... other hand, the rod sources. TIG welding is generally more expensive and more difficult to make because there is often remote amperage included pedal and it takes a cylinder of argon or argon shielding gas mix to work.
TIG welding is the most versatile type of welding. Almost all conventional metals can be welded with the TIG process. Aluminum and aluminum alloy steels, stainless steels, nickel alloys, aluminum, magnesium, titanium, cobalt, copper and alloys can be welded using this type of welding.
Plasma welding
Plasma welding is similar to TIG welding, except that the tungsten electrode is recessed within the nozzle and the heat is created by ionizing gas flows around the arc. Plasma welding is used where high precision is required and situations where a recessed electrode is beneficial. Plasma welding is often used in aerospace applications for dimensional reconstruction of the air seal and jet-engine blade repair, where the thickness is often below the 0.015 "and amperages often used a single digit.
Gas welding
Gas welding is one of the old school types of welding. oxygen and acetylene is the most popular setup kit for gas welding and gas welding is still used a lot for automotive exhaust applications, and homebuilt aircraft enthusiasts for welding 4130 chromoly tubing for aircraft fuselages. It works. It is portable. And it is quite versatile ... There are still some people who swear by gas welding even for aluminum welding.
Some people believe that TIG welding is much better than gas welding. I am one of those people.
, electron beam and laser welding.
These types of welding are considered high-energy welding processes, because they pinpoint the heat much better than the older more conventional types of welding. Electron beam welding can penetrate 6 inches of steel, no dents.
Laser welding heat can be determined so precisely that the weld metal can be deposited on tool steel injection mold cavity so precise that heat treatments can be eliminated, and only minimal processing is required in order to restore dimensions.
