The aim of the course is to enlighten the students on various aspects of industrial modern welding processes. To enhance the course, laboratory tutorials and exercises uses practical examples of welding designer tasks. After having passed this course, the student:

  • has a thorough knowledge of most important welding processes that are used in industry, knows their peculiarities and typical applications
  • knows the principles of processes and understand in selecting most suitable welding processes for specified applications with consideration of usability, productivity, and economy aspects.
  • understands the relationship between welding process, quality, cost-effective welding production, energy saving in welding, and sustainability of selecting suitable welding process for different applications.
  • has a general overview of utilizing standards like SFS-EN-ISO in welding production, safety and quality management, as far as they concern welding processes.

The course consists of lectures, exercises and an obligatory visit to an industrial company or laboratory tutorials to make the student familiar with industrial welding processes and practices. Lecture topics are listed below:

  • Major parameters, productivity, usability, and efficiency of major welding processes (Manual Metal Arc (MMA) welding, Gas Metal Arc Welding (GMAW), Metal Inert Gas, Metal Active Gas (MIG/MAG) welding, Submerged Arc Welding (SAW), Tungsten Inert Gas (TIG) welding, Plasma welding, Friction Stir Welding (FSW), Laser welding, Electron Beam welding, Hybrid welding, Resistance welding and other)
  • The concept of materials weldability
  • Mechanization/robotization/automation of welding processes
  • Basics of welded structures design
  • Welding grooves preparations: cutting and beveling methods
  • Quality, sustainability and safety aspects in a welding workshop


Each lecture has an exercise, which consists of multiple choice /open questions, and some practical assignments based on industrial tasks of a welding engineer, for instance:

  • Compare welding processes by productivity and usability aspects
  • Define weldability of a certain material
  • Describe features of a certain automated welding process
  • Evaluate proposed welding designs
  • List features concerning welding quality and its control


Additionally, the course has obligatory seminar, which is a report of 10-20 pages written by the student for the whole duration of the course. Example topics are:

  • Principle, operational parameters and novel developments of a certain welding process
  • Weldability of a material group
  • Benefits and concerns of welding mechanization/robotization/automation
  • Welding quality control for a specific welding process
