Metal Inert Gas / Metal Arc Gas (MIG-MAG)

Metal Inert Gas / Metal Arc Gas (MIG-MAG) Welding Course

AIM
To train Welders on the MIG welding process from the basics, to a terminal test and through to ASME 1X and BS/EN 9606-1 or BS/EN 9606-2.

Pre-Requisite
Previous knowledge of Manual Metal Arc Welding would be advantageous.

Course Duration
5 to 20 days, dependent upon the ability of the learner.

Maximum Number
3 – 4 persons.

Training Aids
Demonstrations and practical exercises

Assessment
Visual inspection of the trainees’ practical work and a terminal test to ASME 1X and BS/EN 9606-1.

Certification
On successful completion of the course candidates will receive a NETA certificate. The certificate will be sent directly to the delegate or their sponsor company.
