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
  • AA3.1, AA3.2
  • AA5.2, AA5.4
  • AA6.1, AA6.2, AA6.4
  • 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.
 
Content
  • 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.
  • Metallurgy of fusion welding
Teaching methods
Lectures, pratical laboratories with small groups of students and exercices
Integrated Welding Project: Welding, Heat Transfer, Micrography, Testing, and Critical Analysis
Evaluation methods
Integrated Welding Project with Oral Presentation: 20% of the Grade
Oral Examination with Written Preparation: 80% of the Grade
In the event of a health situation requiring the switch to distantial mode, the oral exam will be held on microsoft teams
