Award in Tungsten Inert Gas (TIG) Welding (GTAW)

Malta cohort commencing on the 18.11.2023. 

Lectures will be delivered every Saturday from 12:00 [Midday] till 16:00 

There are limited places available and applications are handled on a first-come-first served basis. Applications exceeding class limit will be included in the next cohort starting on 06.04.2024. 

The course is designed for those determined to obtain a qualification to enter the industry with enough skills to produce simple welded TIG joints on non-complex positions and also for those that want a qualification for their own personal requirements.

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

This is a 40 hrs of guided learning course.  Students need to invest further hours in the course, which will include private study and home assignments.

Lessons are as indicated on the prospectus and website.

The course is based on a series of practical exercises to produce good welded products in terms of performance of appearance.

Unit 1 – TIG Simple Welded Joints Practice (30hrs)

Learning Outcome 1:  Carry out  essential preparation prior to the welding process.

Unit Content

• • Preparation of material (parent material: low carbon steel plate – 150 mm long by 50 mm wide minimum dimensions and by 3 to 6mm thick. Acceptance is only by visual inspection.

• • Alignment of plates before welding; Setting of welding equipment

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

Unit Content

• • Weld Simple beads on a steel plate in the flat position

• • Weld Lap Fillet Joints in the horizontal/ vertical position

• • Weld Tee Fillet Joints in the flat position

• • Weld Tee Fillet Joints in the horizontal/ vertical position

• • Weld Corner Joints in the flat position

• • No specific requirement to intermitted restart of weld is included in the above welds.

• • Parent material: low carbon steel plate – 150mm long by 50 mm wide minimum requirements by 3 to 6 mm thick. Acceptance is only by visual inspection.

Unit 2 – TIG Technology and Safety (10hrs)

This unit is based on a series of practical exercises to produce good welded products in terms of performance of appearance.

Learning Outcome 1:  Identify hazards when working with Tungsten Inert Gas Welding equipment

Unit Content

• • Fires and explosions, burns, fumes, electric shock, toxic gases generated by welding processes, radiation heat stress dust, appropriate personal protective equipment

Learning Outcome 2:  Identify hazards when working in teams at the place of work

Unit Content

• • Excessive noise; unexpected tripping hazards; access and scaffolding hazards; escape routes; warning signs; safety lines; safety rails; emergency lighting

Learning Outcome 3:  Identify Tungsten Inert Gas Welding equipment and accessories

Unit Content

• • Weld Set; TIG torch; Different TIG torches: (water/ air cooled); Power Supply; TIG filler rods; Shielding Gas

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

Entry Requirements:

• • Over 16 years old and satisfactory completed the MCAST Introductory Course in Welding.

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)
