Welding and Information About Different Types of Welding

Go Welding.Org is all about welding! The welding information on this site is about the four most common types of welding processes and how to become a certified welder. The welding processes this site is focused on are:

These are the types of welding processes that are taught in welding schools and are used in the majority of industries from ship building to nuclear power plant construction. If you have any doubts just search any employment ads for welding jobs or visit a welding supply store!

Stick Welding Flux Cored Arc Welding TIG Welding

Many of the subjects covered here are not even found in text books, online, or in welding schools. This is detailed information I wrote down and took pictures to reference too while working and becoming a certified welder again. It comes down to the small details that you learn while welding that make a big difference. I will always be adding more information as my career moves on. While writing much of the content I have been lucky enough to get advice from some of the best welders in the field. A lot of the advice on here is also what I learned from welders that have literally mastered and perfected their skills to the highest level! So far this is only the beginning of this site and one day hope to make it a place where you will be able to find anything you need related to welding.

Finally, if you like this site and have found it really helpfull tell your friends, teachers or anyone who can use by linking to it and spreading the word or just add your vote with the Google button on the left.! I am just one person and any help that I can get is more then welcome...

Learning How to Weld Online

TIG Welded Pipe

For anyone interested in learning how to weld, your best bet is to sign up for a welding class! Everything else is just a guideline (including this site)! Welding is learned through hands-on training and practice. That being said, there are no DVD’s, videos, books, or websites that can teach you how to weld without real life practice. It’s just like driving a car! You will only learn by getting the right information and then spending a lot of time behind the wheel. Welding is a Very Highly Skilled Trade and takes 1000's of hours to learn. Anyone who can master and perfect this skill can easily make a doctor's salary or more! Even as I am writing this in a down economy and being a high school drop out; I am earning close to $40 an hour and have the option to work all of the overtime I want! Then there are others who travel overseas who are making mid six figure salaries. No other construction skill pays as much because no other skill is as difficult to learn.

If you want to learn how to weld, again I would strongly advise anyone to sign up for a welding class. Save yourself the time and money on videos and the so called “learn how to weld online courses”! When searching for a Welding School you should always ask if they also offer AWS welding certifications, or better yet, contact the Hobart Institute of Welding Technology at www.welding.org or get into a NCCER training program!  If you want to find a local welding school or need to take a welding certification, go to the right source and try the AWS School Locator www.aws.org/w/sense/ . This is the best place to find local welding schools and training centers!

What is Welding?

Welding is nothing more than the art of joining metals together. By comparison, wood is joined by nails, bricks are held together with mortar; metal is joined by welding! What makes welding such a big deal is that the world’s infrastructure depends on it! Everything you touch everyday that is made of metal is most likely welded in one form or another. It is one of the most valuable technologies that played a huge part in the industrial revolution, and is the back bone to the world’s militaries. Welding today is comprised of three main ingredients wich are required to join metals together.

  • An electrical power source to produce an arc.
  • Some form of shielding to protect the weld from the air.
  • Filler material to fill the weld joint.

The ways these three ingredients work together are:

  • First, the weld area needs to be shielded from any air around it. This is important because oxygen and other gasses in the air make welds brittle and porous.
  • Second, is the electricity to produce an arc. An electrical arc melts metal in fractions of a second and is hot enough to melt any known metal!
  • Finally, the filler metal is added, which is how two pieces of metal become one.

That’s how welding works and that is all there is to it!

Stick Welding

Stick Welding is a slang term commonly used for Shielded Metal Arc Welding or “SMAW”. Stick welding is the most basic and common type of welding processes used. It is also the first process learned in any welding school. Stick is the most trouble free of all of the welding processes and is the fundamental basis for all the skills needed to learn how to weld!

Stick welders have four main components.

  • A ground lead or clamp.
  • A welding lead or stinger.
  • A constant amperage power source.
  • The electrode or welding rod to weld with.

The process is simple! The ground clamp is attached to the work or metal to be welded. Then the welding lead, or stinger, gets the electrode inserted in it. Finally, the power supply is turned on and only requires the user to strike the metal to ignite it. Once that is done. the arc starts and the electrode begins to burn. This creates a shielding gas and deposits metal into the joint that is being welded. The slag from the electrode needs to be cleaned or chipped off as soon as the weld is finished.

TIG Welding

TIG Welding is also a slang term commonly used for Gas Tungsten Arc Welding or “GTAW”. TIG welding also goes by the term HeliArc welding. TIG welding is the most difficult of the processes to learn, and is the most versatile when it comes to different metals. This process is slow but when done right it produces the highest quality weld! TIG welding is mostly used for critical weld joints, welding metals other than common steel, and where precise, small welds are needed.

TIG Welder with all the Bells and Whistles

TIG welders have six main components:

  • A constant amperage power source (many times a Stick welding power supply).
  • A ground lead or clamp.
  • A welding lead or TIG Torch.
  • A non-consumable Tungsten electrode to produce the arc (the Tungsten electrode does not add to the weld joint).
  • Shielding gas to protect the weld area from the air (typically pure Argon gas).
  • The filler wire to add to the weld joint with the other hand.

TIG welding equipment varies greatly in the sense of bells and whistles. The simplest TIG welders are a Stick welder power supply with a TIG torch attached to the welding lead, and the other hose is attaches to a bottle of Argon gas. This is how the largest defense contractors and engineering companies set-up thereTIG welders for Pipe. The way this process works is simple. First the ground clamp is attached to the metal to be welded, a Tungsten electrode is inserted into the TIG torch, the Argon gas is turned on and now the torch is feeding Argon gas through the torch, the power supply is turned on, and now all it takes is a scratch of the Tungsten to strike an arc. Once the arc strikes the Tungsten just produces an arc and starts to melt the metal, after that you simple add filler wire to the joint with the other hand.

MIG Welding

MIG Welding is a slang term that stands for Metal Inert Gas Welding, the proper name is Gas Metal Arc Welding or “GMAW”, and it is also commonly referred to as “Wire Wheel Welding” by Unions. MIG Welding is commonly used in shops and factories. It is a high production welding process that is mostly used indoors.

MIG Welders have five main components.

  • A constant voltage power supply.
  • A wire feed to feed the filler wire through the welding lead to the MIG gun.
  • A ground lead or clamp.
  • A welding lead or MIG gun.
  • Shielding gas to protect the weld area from the air.

MIG welding is not that simple when it comes to setting up the equipment but the skill required is a lot less then Stick welding. The way MIG welding works is you attach the ground clamp to the work then power source is turned on and finally the shielding gas needs to be turned on. After that you need to set the voltage, wire feed speed that is counted in IPM (inches per minute), and shielding gas flow rate that is counted in CFH (cubic feet per hour). Then simply hit the trigger and the MIG gun starts feeding shielding gas and wire to the weld joint. Once the wire hits the weld joint it begins to arc and the wire melts and starts filling the joint.

Flux Cored Arc Welding

Flux Cored Arc Welding

Flux Cored Arc Welding “FCAW” is nothing more than a different welding wire or electrode for a MIG welder! FCAW wire is a hollow or tubular wire that has a flux inside of it that provides a shielding from the air when it is welding. What this does is help a MIG welder to weld in windy conditions and it increases how much weld can be welded per hour. The powder flux inside also has metal mixed in that increase the weld deposit rate.

FCAW is the fastest of all of the manual welding processes. FCAW wire has two types.

  • Self Shielding.
  • Dual Shielding.

Shelf shielding wire is just that! It has enough flux inside that no other shielding source is needed.

Dual Shield is a wire that helps shield the weld but also needs a source of gas just like a MIG welder.

Flux cored arc welding is similar to Stick welding when it comes to slag. It also has a slag that covers the weld that needs to be cleaned after the weld is finished.
