Understanding the basic principles of welding technology development as a prescribed flow of activities to be followed when making each welded joint in the structure. Introducing students to the techniques of material selection, preparation, thermal cycle of welding, methods of ensuring and controlling the quality of welding and possible subsequent activities, subsequent heat treatment. Understanding and making examples of welding technology. Development of independent work by making and presenting selected seminar papers.

By attending the course, the student masters the basic skills and principles for the development of welding technology for a specific case. Theoretical considerations, as well as computational examples allow the student to master all the necessary principles of welding technology needed to make different types of welded joints. Introducing students to the existing modern standards and recommendations in the field and developing a critical way of thinking about them.

Introduction to the basic principles of welding technology. Defining the previous welding procedure specification (pWPS). Qualification of previous welding procedure specification (WPQR). Welding procedure specification (WPS) - analysis of documents defined by the standard and necessary to contain data on the manufacturer, base material, welding procedure and position, joint preparation, groove and groove edges, welding technique, additional material, all welding parameters, preheating temperature and interlayer temperature ... Heat treatment after welding. Welding sequence. Qualification of welders - analysis of standard EN 287-1 which includes the principles on which the test of professional competence of welders for fusion welding of steels is based ...

Classroom exercises with examples of tasks from welding technology. Preparation of preliminary specification of welding technology - examples include different types and thicknesses of base material, welding procedure and position. Development of tasks from the qualification of welding technology - examples include different types and thicknesses of basic material, welding procedures and positions, as well as the method of qualification. Presentation and defense of selected seminar papers.

necessary: Mechanical materials 1,2,3; Basics of welding B (M); Welding metallurgy
