Basic Electric Arc Welding


The Training Course is primarily intended for Engineer Officers who will be involved in electric welding works for the repair and maintenance on the vessel.

It has a limited duration of 3 days, combining theory and hands-on training, with a focus on materials and welding works, commonly done on a ship.

The delivery of this Training Course marks the cooperation of the ATHINA MLDC with the Technology and Quality Control Center (TQCC), in the area of electric arc welding training.


On completion of the seminar, the participating Engineer Officers, will be able to:

  • Make fillet and groove welds in a variety of positions.
  •  Safely and correctly use the MMA Welding Machines.
  • Recognize weld faults and identify the methods required to rectify.
  • Decide of the type of electrodes to be used, adjust the arc and prepare the wedges to bewelded.


The training course will take place at the ATHINA MLDC Training Facilities/Electromechanical Laboratory.

There are (4) fully-equipped, side-to-side, arc welding booths with metal benches, on which, the work pieces can be cut/grinded and welded. Each booth has its own extraction hood to draw away the fumes from the welder, an arc welding machine (inverter based welding rectifier, 200 A), hand tools, including portable angle grinders, etc. A classroom, near to the working booths, is available for hosting the theoretical part of the course.


The Technology and Quality Control Center (TQCC) is based in Greece, and its main activities include certified training and consultancy services on Welders’ Training and Supervising, Non- Destructive Testing and Welding Processes Specifications.

Two TQCC Trainers, a Welding Engineer Level 3, and a Certified Welder with a long experience
in new buildings and ship repairs will carry out the training course.
