Welding TIG (Lift-Arc) Course – TIG (GTAW) Lift-Arc Familiarisation Workshop for Marine Engineers
Description of the course
This 5-day practical workshop provides an introduction to TIG (GTAW) welding using the Lift-Arc starting method, with a focus on carbon steel and applications relevant to shipboard maintenance and light repair work.
The training combines essential TIG theory with extensive hands-on practice in the Novikontas welding laboratory in Riga. Each participant is provided with an individual welding station and the necessary welding equipment, consumables, shielding gas and personal protective equipment.
