The Basics of Gas Tungsten Arc Welding (GTAW/TIG) from Udemy

Welcome to the Udemy course titled, "The Basics of Gas Tungsten Arc Welding (GMAW, TIG)" If you are new to the field of welding, this is the class you need to learn some of the over-arching concepts of welding and THE FULL RANGE OF BASICS associated with GMAW specifically.

GMAW (Gas Tungsten Arc Welding) is commonly referred to as "TIG" welding, which stands for "Tungsten Insert Gas". TIG of GMAW refer to the process of using a non-consumable tungsten electrode to deliver electrical current to your work piece. Tungsten has a very high melting point relative to other metals, so it holds up well to the high temperatures of welding. GMAW also employs the use of a shielding gas like argon or helium. This gas prevents the oxygen and nitrogen found in our atmosphere from contaminated the weld pool.

TIG welding is very precise when compared with other welding processes. It deposits a low volumes of material in exactly locations. It is commonly used on metals such as aluminum and copper, or thin sections of steel sheet. And because of its versatility, TIG is often the first process new welders learn.

In the class, you will learn:

An Overview of GMAW
Advantages and Disadvantages as compared to other welding processes
Welding current
The TIG Torch and Gas Shielding System
Electrodes
Filler and Base Materials
Welding Terminology
Pre-weld Preparations
Primary and Secondary Welding Variables
Welding Defects and Discontinuities
And a Whole Lot More.
