Types of Welding tig,mig,stick and gas welding

1
Types of Welding

• TIG, Stick, and MIG

2
TIG, Stick, and MIG Make Up 90 of All Welding

• What are the different types of welding and what
  are they used for? If you are looking for a
  20,000 foot view of the different types of
  welding along with applications, stick around for
  a minute, I think I can help.

Stick welding

• Stick welding is often called Arc welding
• Stick welding is the old school kind of welding
•  It uses a stick electrode like a 6013, 6011, or
  7018 welding rod
• The rod is struck like a match to get the arc
  going and the rod is fed into the puddle as it
  burns

4
MIG welding

• Mig welding is considered one of the easiest
  types of welding to learn.
• rod does not have to be fed as it shortens like
  with stick welding
• A wire is fed through a cable and out the end of
  the mig welding gun and all the operator is
  required to do is to pull the trigger and weld
• Mig welding actually kind of describes 2 types of
  welding
• Bare wire mig is cleaner, and will weld thinner
  metal, but flux core is easier to use outdoors
  and does not require a cylinder of mig welding
  gas or a flow meter
• Mig welding helmets also have lighter shades as
  compared to other types of welding

5
TIG welding

• Harder to master than mig or stick welding
• Both hands are needed to tig weld
• One hand holds a tig torch with a tungsten
  electrode that provides the arc and heat
• Other hand feeds the rod
• TIG welding equipment is generally more expensive

6
TIG welding uses

• Virtually all conventional metals can be welded
  with the tig process
• Carbon and low alloy steels, stainless steel,
  nickel alloys, aluminum, magnesium, titanium,
  cobalt, and copper alloys can all be welded using
  this type of welding.

7
Plasma arc welding

• Plasma arc welding is similar to tig welding
  except that the tungsten electrode is recessed
  inside a nozzle and the heat is created by
  ionizing gasses flowing around the arc
• Plasma arc welding is used extensively in
  aerospace applications for dimensional
  restoration of air seals and jet engine blade
  repair where thicknesses are often below .015"
• Amperages used are often single digit.

8
Gas welding

• Gas welding is one of the old school types of
  welding
• Oxygen and Acetylene is the most popular setup
  for a gas welding kit
• gas welding is still used a lot for automotive
  exhaust applications
