Tungsten Inert Gas (TIG) Welding - (GTAW)

The course is designed for those determined to obtain a qualification to work in the industry with enough skills to produce sound TIG welded joints in a selection of positions to industry requirements.

This course provides progression across a range of welding processes and also progression to higher levels.

This is a 60 hrs of guided learning course.  Students need to invest further hours in the course, which will include private study and home assignments. 

Lessons are held as indicated on the prospectus and website.

Unit 1: Production of Simple Welded Joints

This unit is based on practical exercises to produce sound welded products in terms of performance of appearance and in terms of results following cupping test, nick-break fracture test and macro section examination.

Learning Outcome1: Carry out essential preparation of material for welding

Unit Content


  • Preparation of material , mainly Austenitic Stainless Steel – 200 mm long by 50 mm wide minimum requirements and by 1.5 to 3.2 mm thick.  Acceptance is by visual inspection and destructive tests.

Learning Outcome 2: Weld steel plates using single-run Tungsten Inert Gas (TIG) Welding

Unit Content


  • Weld butt joints in the flat position
  • Weld a lap fillet Joints in the vertical-up position
  • Weld Tee Fillet Joints in the vertical-up position
  • Weld butt joints in the vertical-up position
  • Weld tube-to-plate tee fillet in the horizontal/ vertical position

Unit 2:  Explore Technological Tungsten Inert Gas (TIG) Welding Knowledge

This unit covers common technical specifications of Tungsten Inert Gas welding equipment and accessories, their proper use to produce good sound welds and the proper procedures that should be adopted when working individually and in an industrial environment under supervision.            

Learning Outcome1: Follow Health and Safety procedures at the place of work when working with Tungsten Inert Gas Welding equipment

Unit Content


  • Hazards from the welding torch; Gasses, Gas Cylinders, Gauges and hoses; Electrical hazards; ventilation at the weld station and in general, use of tools, ladders and scaffolding

Learning Outcome 2: Work in a team

Unit Content


  • Handing over of equipment between shifts; reporting procedures of faults; routine checks between colleagues during working hours

Learning Outcome 3: Outline the process specific requirements of Tungsten Inert Gas Welding

Unit Content


  • Type of: Torches; Weld sets; TIG Filling Materials; Tungsten bits; Gasses and Gauges

Learning Outcome 4: Test the basic destructive requirements of Tungsten Inert Gas welds

Unit Content


  • The cupping test, nick-break fracture test and macro section examination.

The following are the suggested pre-requisites and/or entry requirements needed:

Pre- Requisites:


  • 16 years of age

Entry Requirements:


  • Completed successfully the Level 2 course in Tungsten Inert Gas (TIG) Welding. Can take own responsibility to follow technical procedures and safety and health procedures.

Course participants may be awarded either an MCAST Certificate of Attendance or an MCAST Certificate of Achievement.

MCAST Certificate of Attendance


  • An MCAST Certificate of Attendance will be awarded to those candidates who attend at least 80% of the lessons.

MCAST Certificate of Achievement


  • An MCAST Certificate of Achievement will be awarded to those candidates who satisfy the 80% attendance criteria AND ALSO choose to sit and pass the course assessment/s.
  • Students who opt not to sit for the assessment/s or fail (the assessment/s) will however be awarded an MCAST Certificate of Attendance provided that they fulfill the minimum attendance criteria as stated above.

If the student intends to obtain a Certificate of Achievement, she/he is required to sit for an assessment/s.  Assessment/s may take various forms such as a home assignment, class assignment, practical test and time constrained test.  However, the assessment/s is not compulsory and an applicant may choose not to sit for it.

During the lessons, students should have their own safety gear to industry standards.  (Gear to include safety shoes, cotton boiler suit, safety glasses and gloves)
