But in the 18th century a man named Sir Humphrey Davey created the first arc between two carbon electrodes using a car battery. This marked the start of modern arc welding. Many different people then went on to discover different types of welding finally leading to the invention of TIG welding in 1941 by a man named Russel Meredith.

Reflection: This article gave me a step by step guide to the history of welding as a whole. It gave exceptional descriptions of events and significant scientific discoveries that lead to each new technique. The article even included a organized time line of all metallurgy developments since the bronze age.

The patent was purchased by the Linde Division of Union Carbide who then produced components and accessories for the process until the early 1970s when the patent expired. After that many companies took over production, the lead of which was CK worldwide.

Reflection: This article gives good information on the technicalities of TIG welding history. Giving details about companies and production processes that led to the development of the TIG machines we use today.

In AC processes the shielding gas is ionized in such a way that it produces a cleaning action that's good for removing oxides on metals like Aluminum and Magnesium. To begin welding the machine first needs to be set up properly, then the pedal is depressed and a gentle arc is lit. After pressing harder on the pedal a pool of molten metal should form on the base plate where the arc meets it. That puddle can then be used to melt filler metal and weld multiple pieces of metal together.

Reflection: I thought this article was very informative and gave many tips for better TIG welding. It also explains the science behind the process and the significance of shielding gas when welding. Overall it provided a good overview of the TIG process as a whole.

TIG electrodes are decided based on the parameters of the job. There are a variety of types of tungsten electrodes that are each good for certain things, for example pure tungsten is good for AC welding on aluminum while 2% Thoriated is best for DC on carbon steel. One significant challenge to TIG welding is its high-difficulty level, it can take years to master TIG welding in any meaningful way.

Reflection: This article gave a lot of detailed information regarding the specifics of a TIG set up. It gave a detailed list of tungsten electrodes and their advantages/disadvantages as well as an explanation of their purposes. This article was very informative regarding both the negative and positive aspects of TIG welding.

These different alloys produce a variety of effects on the characteristics and heat capacity of the tungsten. Pure tungsten and %2 thoriated tungsten were the standard for many years until newer developments brought a variety of other alloys that improved upon the originals. The tungsten preparation also has an effect on how it welds. A longer sharpened tip produces a wider arc, whereas a stubbier tip produces a thinner arc. Each has its uses but it is up to the welder to decide what the best preparation is for their weld.

Reflection: Ron Cowell describes many informative aspects of TIG welding in this article that give an explanation to the different types of tungsten electrodes that can be used. It is incredibly useful for deciding the proper tungsten alloy to be used for a chosen weld. For any type of AC welding he suggests that a Ceriated or Zirconiated tungsten would be the best choice. For DC welding, Ceriated is still a good choice but Thoriated or Lanthanated would also work.

Not the least of which is welding all different types of metals that are not able to be welded easily through the stick or MIG welding processes. TIG is used for welding dissimilar metals to each other, welding metal that is too thin for other processes, or welding metal that is just too finicky to be welded with a more aggressive method. TIG is very clean and precise which is good for almost all different types of metals. In the case of rare earth metals, TIG can be used for many different alloys that would end up a molten mess with most other processes.

Reflection: TIG is a good process for any kind of metal that isn't the basic aluminum or steel. The article demonstrates this through an excellent explanation of the process of TIG welding and the properties that make it good for different types of metal. It is very clean, easy to manipulate, and only requires a change in filler rod and possibly polarity to be able to weld even dissimilar metals together.

It uses an inert shielding gas and a non-consumable tungsten electrode to produce a very clean and hot arc without causing any imperfections to be produced in the weld pool. TIG is incredibly useful for welding many types of metals, much more than any other process. In the case of exotic metals, TIG welding is by far the cheapest and most accessible method of welding and is still chosen by many high-quality welders over modern processes like laser welding. TIG welding is used when a incredibly clean and delicate process is required. Projects like welding thin or rare metal usually call for the use of TIG welding.

Summary: This article gives a good overview of the TIG welding process as well as many of it's uses. One thing that stood out from the others is it's use on rare metals. TIG welding is incredibly clean and thus is easy to use on exotic metals that normally would require an entirely different flux or cleaning process otherwise. With TIG welding the only difference is a change in the filler rod material and/or a change in the polarity. This article shows the usefulness of TIG welding in this, and many other ways.

Welding melds two base metals to each other by melting the base metal and filler metal together. The main mechanical difference lies in the temperature used for each process. Brazing and soldering are both much colder processes than welding, due to the fact that they don't melt the base metals together. Brazing would be used for parts that don't need to hold structural weight or pressure, it's mostly used for delicate jewelry or electrical components.

Reflection: Brazing and welding are two very different processes that are used for two very different applications. The article clearly shows that welding is used for structural and pressure vessels while brazing is usually used for less important aesthetic parts. It also goes into detail about the idea of melding dissimilar metals together, which brazing is incredibly good at doing since it doesn't actually melt the base metals, just the filler rod. This is good for many different applications but not anything that needs to hold weight.
