FAQs
What is CO₂ Welding Training?
CO₂ Welding Training teaches learners the theoretical knowledge and practical skills required to safely weld metal using a continuous wire electrode and CO₂ shielding gas. The course covers welding equipment, machine setup, material preparation, welding techniques, safety procedures, and weld quality.
How long does CO₂ Welding Training take?
Our CO₂ Welding Training Course takes 4 weeks to complete, combining theory training, hands-on practical workshop training, and competency assessment.
How much is CO2 welding?
Our CO₂ Welding Training Course costs R8,500, including theory training, practical workshop training, and competency assessment.
What is CO2 used for in welding?
CO2 is used as a shielding gas in CO2 welding to protect the molten weld pool from contamination by oxygen and nitrogen in the surrounding air. It helps produce a strong weld, provides good penetration and supports stable welding when the correct settings are used.
Is CO₂ Welding Training practical?
Yes. Learners receive extensive hands-on workshop training where they practise machine setup, wire feeding, gas adjustment, material preparation, welding techniques, and producing quality welds under professional supervision.
How much does a CO2 welder earn in South Africa?
A CO2 welder in South Africa can earn between R28,000 and R47,102 per month, depending on experience, welding skills, employer and industry.
Which is better, CO2 welding or arc welding?
Both welding methods are useful, but they serve different purposes. CO2 welding is better for faster production, continuous welding and fabrication work, while arc welding (stick welding) is versatile and suitable for construction, repairs and outdoor welding. The better option depends on the type of welding work you want to do.
Is CO2 welding MIG or TIG?
CO2 welding is a type of MIG/MAG welding. More accurately, it is called MAG welding (Metal Active Gas) because it uses carbon dioxide (CO₂) as an active shielding gas. It is not TIG welding. CO2 welding uses a continuously fed wire electrode, while TIG welding uses a non-consumable tungsten electrode.
What is the difference between MIG welding and CO2 welding?
MIG welding uses an inert shielding gas, such as argon or an argon mixture, while CO2 welding uses carbon dioxide as an active shielding gas. Both use a continuously fed wire electrode. Technically, CO2 welding is classified as MAG welding, not MIG welding, because CO2 is an active gas.
Is CO₂ Welding easy to learn?
Yes. With proper instruction, practical guidance, and consistent practice, learners can develop the skills and confidence required to perform CO₂ welding safely and professionally.
What does a CO₂ Welding Course cover?
The course covers MIG/CO₂ welding principles, welding safety, PPE, machine setup, wire and gas selection, metal preparation, welding positions, joint types, weld defects, quality inspection, and practical welding techniques.
CO₂ welders can pursue opportunities across sectors such as construction, manufacturing, engineering, mining, fabrication, automotive, industrial maintenance, infrastructure development, and general metalworking.
How many months is a welding course?
Our welding course takes 1 month to complete and includes practical training to help learners develop essential welding skills, understand welding equipment and perform basic welding tasks.
What is a CO2 welder?
A CO2 welder is a welding machine operator who uses carbon dioxide as a shielding gas during the welding process. The process uses a continuously fed wire electrode to join metal components and is commonly used in fabrication, manufacturing and construction.
Which gas is used in CO2 welding?
CO2 welding uses carbon dioxide (CO₂) gas as its shielding gas. It protects the molten weld pool from contamination by the surrounding air and helps produce strong welds.
What career opportunities are available after CO₂ Welding Training?
Completing CO₂ Welding Training can prepare learners for roles such as CO₂ Welder, MIG Welder, Welding Technician, Fabrication Welder, Structural Welder, Production Welder, Manufacturing Welder, Workshop Welder, Metal Fabricator, and Welding Assistant.
