Introduction
Gas Tungsten Arc Welding (GTAW), also known as tungsten inert gas (TIG) welding is a process that produces an electric arc maintained between a non-consumable tungsten electrode and the part to be welded. The heat-affected zone, the molten metal, and the tungsten electrode are all shielded from atmospheric contamination by a blanket of inert gas fed through the GTAW torch. Inert gas (usually Argon) is inactive or deficient inactive chemical properties. The shielding gas serves to blanket the weld and exclude the active properties in the surrounding air. An inert gas such as Argon and Helium, do not chemically react or combine with other gases. They pose no door and are transparent, permitting the welder maximum visibility of the arc. In some instances, Hydrogen gas may be added to enhance travel speeds.
The GTAW process can produce a temperature of up to 35,000O F (19,426O C). The torch contributes heat only to the workpiece. If filler metal is required to make the weld, it may be added manually in the same manner as it is added in the oxyacetylene welding process, or in other situations may be added using a cold wire feeder. GTAW is used to weld steel, stainless steel, nickel alloys such as Monel and Inconel, titanium, aluminum, magnesium, copper, brass, bronze and even gold. GTAW can also weld dissimilar metals to one another such as cooper to brass and stainless steel to mild steel.

Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
Who Should Attend?
This course is ideally suited for all inspection persons to understand the role of Procedure Qualification as a tool for Quality Assurance. This course will be beneficial for Plant inspectors, Third-party inspectors and Shop inspectors, QA/QC personnel, and others involved in Welding qualifications and NDT examinations.
Course Outline
- Learn fundamentals of GTAW (TIG) for steel, stainless steel and aluminium
- Welding procedures are taught on aluminium, carbon and stainless steels
- Welding consists of edge, corner, lap and fillet welds in all positions
- Welding is limited to regular thin, flat material, which does not include thick plate, pipe or other irregular shapes
