MIG, TIG, MMA Welding Programmes

Objective:
To provide delegates with the necessary skills, knowledge and safe working practices to enable them to produce complex welded joints with different materials and in a variety of positions.

Pre-course requirements:
Delegates must be familiar with workshop health and safety and fully understand the dangers of operating in a fabrication / welding working department.

Outcomes:
Successful completion of the course will result in the issue of a SETA certification.

MIG, TIG, MMA Welding Programmes

Introduction
Health & Safety within a Welding/Fabrication workshop
The necessary theoretical knowledge to undertake the practical skills outlined within the programme

Personal Safety

• Use of protective clothing appropriate to the process to be undertaken i.e. goggles, gloves, aprons etc.
• Isolation procedures for gas and electrical systems
• Remedial action in the event of burns
• Routine inspection of gas pipes and fittings
• Action in the event electrical cables and equipment

Equipment

• Safe setting up and economic operation of welding equipment to include:
• Connection of power sources to mains socket
• Connection of secondary cables
• Connection of gas equipment
• Care and selection of welding wire or welding rods
• Checking the system for safe use
• Demonstration and explanation of the effects of:
• Different arc lengths
• Variation of speeds of travel
• Different levels of current (amp) settings
• Effects of filler wire speed settings or welding rods

Preparation

• Preparation of the material to be welded
• Choice of an appropriate technique
• Methods of minimising distortion and welding difficulties
• Selection of the appropriate range (where application) and setting of the correct amperage

Practical

Demonstration and individual practice of welded joints using various materials and thickness:

• Tee joint– Horizontal/Vertical
• Corner joint – Horizontal/Vertical
• Tee joint – Vertical
• Single vee butt – Vertical
• Tee joint –overhead
• Lap joint – overhead

Inspection and Assessment

• To visually examine the weld for:
• Penetration
• Porosity
• Undercutting
• Imperfections

Outcomes: Successful completion of the course will result in the issue of a SETA certificate of completion.
