Welding is really important in fabrication today. It is basically a method of joining 2 materials, normally being metals or thermoplastics. When referring to the other joining techniques available, welding will use a lower overall temperature. The base material is going to be less strong than the result since filler materials are normally very good for welding purposes. Different welding methods exist at the moment on the market, including:

  • SMAW – normally referred to as electric welding
  • GTAW – a great welding technique also known as TIG
  • GMAW – the technique we refer to as MIG
  • FCAW – quite similar to MIG but a specialized tubular wire is used
  • ESW – productive process designed for materials that are thick
  • SAW – automatically consumable electrodes are used

TIG Welding

According to Lincoln Electric automation systems, TIG is a method that is normally really popular, together with MIG. TIG (tungsten inert gas) welding will utilize tungsten electrodes, normally with the addition of filler rods. The inert gas is going to shield tungsten electrodes. Constant current will be put in the machine used for welding in order to generate electrical energy. TIG welding is normally utilized to weld the metals like aluminum or magnesium alloys. It is a technique that is slow when compared with other options but the weld that is obtained is normally of a really high quality.

Main TIG Welding Features

The advantages associated with TIG welding are those that make engineers from all around the world prefer it when compared with other options. The key features that should always be highlighted are the following:

  • TIG is really useful when thin materials need to be welded.
  • Non-consumable tungsten electrodes are going to be used during welding. Various shielding gases are going to be potentially used, with argon and helium being the most popular.
  • Superior welds are going to be obtained and the quality that is received is definitely quite great.
  • No splatter or slag sign remains after the welding is done.
  • The distortion that appears is minimal.
  • Operators will receive really high control over various welding variables of high importance like heat.

TIG Welding Advantages

  • The welding equipment you use will offer a great looking weld bead.
  • The joints created are powerful and quite strong.
  • Variable thickness metals can be welded.

TIG Welding Disadvantages

Just as with every single welding method out there, it is possible that in some cases TIG welding should not be used. There are different disadvantages that should be taken into account, with the following being the most important to remember:

  • A lot of practice is needed to master TIG welding.
  • The process is so much slower than with the other arc welding processes that include a consumable electrode.
  • The process will be a lot more expensive than with other options.

The bottom line with TIG welding is that you want to consider the opportunity whenever it is available for you. As you instantly noticed, the advantages that exist at the moment are so much higher than the disadvantages that people would need to take into account.
