Award in Metal Inert Gas (MIG) & Metal Active Gas (MAG) Welding (GMAW)

This course is designed for students who are determined to obtain a qualification to be able to work in the industry with enough skills to produce sound 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 hr 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.

Students will learn to produce single-run welds (multi-run permissible) in specific positions with specific requirements to intermitted restart of weld. 

Unit 1:   Production of Complete Welded Joints   (50 hours)

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

Learning Outcome 1: Carry out essential preparation of material for welding

Unit Content

• Preparation of parent material (Low carbon Steel – 200 mm long by 50 mm wide minimum requirements and by 0.8 to 3.0 mm thick)
• Alignment of plates before welding

Learning Outcome 2: Weld steel plates using single-run Metal Inert Gas (MIG) 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  Metal Inert Gas (MIG) Welding Knowledge (10 hours)

This unit covers the Metal Inert Gas Welding process, the importance of following technical procedures and health and safety issues when working individually and in a team.

Learning Outcome 1: Follow Health and Safety issues at the place of work when working with Metal Inert Gas Welding equipment

Unit Content

• PPE, Electrical condition of MIG sets, Ventilation at weld station and in general, Safe use of stools, ladders and scaffolding; Gases, gas cylinders and gauges

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 Metal Inert Gas Welding

Unit Content

• MIG weld set, MIG weld wire, use of different gasses for MIG, simple production output comparative studies

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

Unit Content

• The two root bend tests; nick-break fracture test; 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 course Metal Inert Gas (MIG) Welding Level 2 in the relevant weld process. 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)
