Explore the essential equipment for gas tungsten arc welding (GTAW/TIG), including power supply, torch, tungsten electrode, grounding, and shielding gas with argon or helium, plus torch types and filler options.
Learn gas tungsten arc welding current types—direct current, pulsed current, alternating current with high-frequency start—exploring electrode polarity, heat distribution, aluminum oxide cleaning, and arc initiation.
Explore tungsten inert gas welding, using a non-consumable tungsten electrode and inert shielding gas to protect the weld pool, while filler material is supplied separately via a wire.
In GTAW, filler metal comes from a separate wire. TIG and MIG use the same filler material, only in different product forms.
Learn tungsten electrode tip preparation for GTAW, including tip shapes, material compatibility, and current type (DC, AC) for different metals, plus safe grinding and torch setup.
Explore the tig welding process and its weldable metals, including aluminum, stainless steel, and carbon steels, and learn how ac current cleans aluminum oxide and why tig stays versatile.
Identify crater cracks, longitudinal and transverse cracks, and arc blow in tig welding, and apply prevention methods such as back-off current and proper shielding gas.
Explore a range of manufacturing and quality courses, from Lean Six Sigma and reliability engineering to Excel analytics, designed to boost your gas tungsten arc welding (GTAW/TIG) skills and career.
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
