1 In consideration of the reference table AA of the program "Masters degree in Mechanical Engineering", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:
  • AA1.1, AA1.2, AA1.3
  • AA2.2, AA2.4, AA2.5
  • AA3.1, AA3.2
  • AA5.2, AA5.3, AA5.4
  • AA6.1, AA6.2
  • Understand the main characteristics of each welding process.
  • Choose the best welding process for a given assembly.
  • Understand the physical principles underlying the joining operations by welding.
  • Anticipate the modifications of the microstructure that will be the result of a given welding operation (phase transformation, defects, ').
  • Discuss the consequences of the welding operation on the thermal cycle and the resulting residual stresses and distortions.
  • Welding technologies: gas welding, arc welding, resistance welding, laser and electron beam welding, solid-state welding...
  • Influence of the heat input
  • Heat flow in welds and its modelling
  • Mechanical properties of welds, residual stresses in welded joints
  • Fluid flow in the melt pool of a fusion weld
  • Gaseous reactions in welded joints
  • The evolution of the properties in the heat affected zones of welded joints.
  • Causes and solutions to avoid the main types of cracking.
Teaching methods
Lectures, heat flow project, pratical laboratories with small groups of students and exercices
Evaluation methods
Heat flow in a weld project (15% of the mark)
Oral exam with written preparation (85% of the mark)
In the event of a health situation requiring the switch to distantial mode, the oral exam will be held on microsoft teams
