Award in Manual Metal Arc Welding (MMA) – (SMAW / MMAW)

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. 

This course is designed for those determined to obtain a qualification 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.

In this course students will learn to produce single-run and multiple-run welds in different positions with specific requirements to conduct intermitted restart of weld.

Unit 1 – MMA Sound Welded Joints Practice (50 hours)

This unit is based on a series of practical exercises to produce good welded products in terms of performance of appearance and in terms of results following root bend, macro section and nick-break fracture testing.

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

Unit Content

• • Preparation of material (parent material: low carbon steel plate – 200 mm long by 50 mm wide minimum dimensions and by 5 to 10mm thick. Acceptance is by visual inspection and destructive tests.

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

Learning Outcome 2:  Weld steel plates using single-run/ multiple-run Manual Metal Arc (MMA) Welds

Unit Content

• • Weld Butt welds in the flat position

• • Weld multiple-run tee fillet in the horizontal/ vertical position

• • Weld Lap Fillet Welds in the vertical-up position

• • Weld tee fillet welds in the vertical-up position

• • Weld butt welds in the vertical-up position

• • Specific requirement to intermitted restart of weld must be produced in the above welds.

Learning Outcome 3:  Produce test samples from welded joints

Unit Content

• • Cutting of welded sample to size for destructive testing requirements, polishing and etching for macro examination

• • Parent material: low carbon steel plate – 200mm long by 50 mm wide minimum requirements by 5 to 10 mm thick. Acceptance is by visual inspection and destructive tests against all the acceptance criteria specified in the marking scheme.

Unit 2    –  MMA Technology and Safety (10 hours)

This unit covers the theoretical side of the Manual Metal Arc Welding process, the importance of following technical procedures and the health and safety issues when working individually and in teams with MMA welding equipment. This unit also covers the introduction to technological requirements of destructive testing and macro examinations.

Learning Outcome 1:  Identify hazards when working with Manual Metal Arc 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 Various Manual Metal Arc Welding equipment and accessories

Unit Content

DC/ AC Weld Sets; Electrode holders; Power Supply; Electrodes; Current adjustments

Learning Outcome 4:  Identify various destructive tests

Unit Content

Root bend test; macro section inspection; nick-break fracture test

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

Entry Requirements:

• • Over 16 years of age

• • Completed successfully the   course Basic Manual Metal Arc Welding Level 2  or have the (C&G 3268 Level 1 exams), in the relevant weld process.

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)
