Welding and Metal cutting

This course will enable delegates to acquire H&S accreditation certification through a ‘hands on’ approach using the different electric welding techniques.

Metal-arc welding for the purpose of this standard includes manual metal arc (MMA), metal

active gas (MAG), metal inert gas (MIG), and tungsten inert gas (TIG), spot welding and plasma

cutting. Colleagues must demonstrate, thorough practical activities, their capability in using at

least one form of metal-arc welding, and their knowledge and understanding of:

1. Principles of manual metal-arc welding, the different sources of power, current values, open circuit

and welding voltages, welding returns, welding earth, types of electrode and holders

2. The different types of equipment, safety devices and maintenance

3. The safety regulations which apply to MMA, MAG, MIG and TIG, spot welding and plasma cutting

4. Start-up and close-down procedures

5. Appropriate welding techniques

6. The use of correct personal protection for eyes, face and body

7. Appropriate working environments, ensuring the safety of onlookers with appropriate safety screens

8. Appropriate fire safety devices

9. Health and safety hazards related to electric shock, radiation from arc to both skin and eyes, burns

10. The dangers of toxic fumes from welding and the need for good ventilation
