Name of the program: TIG/MMA welding preparation for the certification – 28 academic lesson/s 

The curriculum group and the start of curriculum development: 521 Mechanics and metalworking. The competence of the fourth category of welding standards. 

Level of education: Additional education for adults 

Languages of study: Estonian, Russian or English 

Training time and volume: Annually, 4 training days (28 academic hours). 

Training Registration Information: On-site Registration 

Target group and starting conditions: Adults (from 18 years old) will be admitted to welder training on the basis of an application. All candidates who meet the requirements for admission and pass the test on the spot will also be admitted to enroll in a course. 

Division into groups: The grouping of students takes into account the level of knowledge and the spoken language.


Total studying volume (academic lesson/s):

28 academic lessons, of which

  • 14 academic lesson/s practice,
  • 14 academic lesson/s Preparation for an exam – Visual control


Methods of teaching: Practical training at an individual welding site consists of performing various tasks of the instructor. 

Online lessons: None 

Studying goal: By the end of the training, the welder will be able to weld a wide range of welding products, parts and building structures. For more aptly done work (for products requiring special control), consult with your supervisor, coordinator or master. The welder uses the following welding techniques: TIG-welding (141, 142), Manual arc welding (MMA 111).

Can properly organize the workplace

Can choose the right self-protective equipment

Can create, assemble parts and create assemblies

Is able to perform quality control and eliminate defects if necessary

Knows welding TIG and trimming

The description of the studying environment: Both theoretical and practical sections will be held at Pae 29, Tallinn. Safety and cleanliness are guaranteed. To study the theory, we have 4 classrooms. Depending on the subject, each class accommodates more than 30 people. The theoretical part is given in-hand (or on memory cards) to strengthen knowledge after the lesson. We also provide both personal protection and work equipment for practical exercises. 

List of training materials: WPS for certification enhancement 

Release requirements, including assessment methods and assessment criteria: At least 80% of attendance is a must for completing the training. In addition, the needed part must be welded in accordance with WPS and must correspond to the evaluation criteria.


Documents to be issued: The complete certificate if the requirements in obtaining it are met. Certificate of completion if the learning outcomes were not achieved, but the student participated in the study. The certificate is issued in proportion to the number of hours visited, but not if the student visited less than half the hours. 

Summary: The course is intended for workers with metal (advanced level), who in their daily work are engaged in high-quality and accurate welding. The course is aimed at acquiring professional practical skills. A student who completed the course will be able to apply the knowledge gained, namely, to weld various materials and details, looking at the Conduction of his daily duties using tools and welding equipment. After completing the course and passing the final exam, the student is ready to work or take an internship.


Formation of the final result:
• Knowledge and the use of professional terminology, successful completion of the practical part of the course
• Visual examination by WPS
