Course Overview:
This course has been developed with an aim of providing trainees with a fundamental and complete understanding of the safety, principles and welding procedures of the Gas Tungsten Arc Welding (GTAW) process.
Learners are going to be instructed on the benefits and limitations of the usage of this technology compared to other welding technologies, how to properly choose an appropriate power source for the process, and the basic welding configuration employed for the GTAW process.
The course covers also preparing and selecting tungsten for welding with alternated or direct current, selection of shielding gases and some of the basic techniques of GTAW welding. It is suited for plant operators, quality assurance/quality control staff, and personnel engaged in the certification of welders as well as personnel involved in non-destructive testing.
The course covers welding of carbon steels, stainless steels and aluminum with different types of weld joints.
Course Objectives:
After completing the course, the trainees must be familiarized with:
- Safety precautions in Welding GTAW Process
- Principles of Gas Tungsten Arc Welding (GTAW)
- Welding procedure of GTAW
- Advantages and Disadvantages of GTAW from another welding process
- Selecting power source of GTAW
- The typical welding system of GTAW
- Selecting and preparing tungsten for AC and DC Welding
- Shielding Gases used in GTAW
- GTAW welding techniques
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 Outlines:
- Introduction to Carbon and Alloy Steel Metallurgy
- Learn fundamentals of GTAW (TIG) for steel, stainless steel and aluminum
- Welding procedures are taught on aluminum, 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
