Aims 

The aim of the course is to guide the student to develop, manage, control and ensure quality and sustainability in welding production. Course exercises features real examples of welding engineer tasks. After having passed this course, the student:

  • understands the meaning of sustainability and quality in welding production
  • knows how to implement quality assurance systems
  • knows quality levels in welding
  • familiar with the concept of Welding Procedure Specification (WPS), its development, approval, and implementation
  • understands welding imperfections and various testing procedures (destructive and non-destructive) of weld joints
  • knows the basic concepts of repair welding
  • understands economics, costs, and productivity of welding
  • familiar with most important welding standards: EN ISO 2553, 3834, 4063, 5xxx, 6520, 6947, 9xxx, 139xx, 14731-2, 156xx, 176xx, EN 1011, 1090, and ISO/TR 15608, 20172.
  • knows the principles of mechanization and automation in welding
  • understands welding networks and supply chains
  • familiar with welding safety and health hazards
 
Contents 

The course consists of lectures, which topics are listed below:

  • Concept of sustainability and quality
  • Welding standards and coordination
  • Welding procedure specification (WPS)
  • Welding defects and imperfections
  • Testing methods in welding production
  • Repair welding
  • Economics, costs, and productivity
  • Mechanization and automation
  • Welding networks and supply chains
  • Welding safety

There are some interactive exercises, and some practical case studies based on industrial tasks of a welding engineer, for instance:

  • Designing Welding Procedure Specification (WPS) according to standards
  • Identifying welding defects from real industrial cases
  • Interpreting results of destructive and non-destructive welding tests
  • Calculating the cost of welding operations
  • Evaluating the safety risks of welding workplaces from real industrial cases

Additionally, the course has an obligatory seminar assignment with presentation, which is a 20-30 pages report written by student for the whole duration of the course.
