Aluminium Alloys and Steels Welding Using TIG and MIG / MAG Processes

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 will provide the necessary basic knowledge and skills to enable learners to perform various types of welds using gas shielded welding processes in a safe manner. It will describe at a micro level the joining process as the weld process occurs and the need for shielding the weld. It will also provide information about the various welding machines available and their mode of operation. It will also give learners sufficient knowledge on how to set and operate these machines. The learners will be provided with sufficient knowledge to be able to choose the most suitable process for particular applications. Learners will have the opportunity to practice various forms of welding techniques applicable to the particular processes. Learners will also be made aware of the hazards associated with the welding processes and instructed on precautions and the proper use of and the safety requirements in P.P.E. A CD containing relevant data will be provided to all participants.

The course is also designed for first time learners wishing to improve their portfolio and possibly open new career horizons.

The course is 50 hours long.  Lessons are held as indicated on the prospectus and website.

This course offers learners the opportunity to develop or increase their ability in welding of metals using the Gas Metal Arc Welding and Gas Tungsten Arc Welding processes namely Metal Inert Gas or MIG and Tungsten Inert Gas processes.

Learning Outcome 1: Take the necessary precautions to ensure Health & Safety requirements before, during and after the weld process

Unit Content

• • Learners will be made aware of :

• • The hazards associated with the welding processes

• • Precautions and the proper use of and the safety requirements in P.P.E.

• • Risks when working with welds processes.

• • Learner will be will be made familiar with:

• • The dangers and precautions associated with welding, including electrocution, high pressures, burning, harmful gasses, and the effect of the welding arc on the naked eye.

• • They will be instructed on the use and importance of:

• • The P.P.E and other safety aspects in the welding environment.

• • The proper use as regards to safety of the the equipment and

• • Hand tools to be used

• • All safety features are in good working order.

Learning Outcome 2: Select the appropriate GMAW and GTAW equipment for a particular situation

Unit Content

• • The  characteristics of the various welding processes

• • Associating various welding processes with the different types of weld.

• • Demonstrate welding processes so learners will have the opportunity to practice using the different equipment available.

Learning Outcome 3: Set the equipment so that it would be suitable for the particular weld application

Unit Content

• • The  different setting parameters available on standard machines

• • Variations in standard machine settings identifying through visual inspection the common weld defects and how these defects can be avoided and rectified.

Learning Outcome 4: Carry out basic trouble shooting related to equipment.

Unit Content

• • Troubleshoot the equipment being used. starting from electricity supply (1ph /3ph)

• • Gases used,

• • Consumables compatibility and standards

• • Wire feeders for GMAW

• • Tungsten use for GTAW.

Learning Outcome 5: Execute GMA and TIG welding on various metals of different thicknesses using different types of joints at different positions

Unit Content

• • Be knowledgeable of the welding processes involved

• • The various types of processes involved such as MIG/MAG &  TIG welding techniques as regards weld executions on different thicknesses and materials ,also joints and positions

• • Consumables standards and pertinent information about the gasses used will be provided.

• • Identifying the proper gases and welding wire / rods to be used in order to achieve a good sound weld.

• • The importance of the edge preparation to be welded and the equipment setting necessary.

Learning Outcome 6: Detect certain surface faults in welded joints by applying N.D.T techniques.

Unit Content

• • Visually inspect welded joints to determine surface flaws

• • Apply N.D.T techniques such as dye penetrant and MPI

• • Identify the defects in welded joints

The following are the suggested entry requirements needed:

Pre-Requisites:

• • Reading and writing. Some basic knowledge about different metals and electricity would be advantageous.

Entry Requirements:

• • Completed compulsory education and a school leaving certificate

An MCAST Certificate of Attendance will be awarded to all students attending more than 80% of lectures.

The course includes an informal assessment that enables the Lecturer to provide feedback to the student.  However, if the student prefers not to undertake the assessment, a Certificate of Attendance will still be issued provided that the student fulfils the attendance criteria (as stated above).

Learners will have to provide their own overall, safety shoes and safety goggles.
