Assembly techniques

Summary

Introduction to the assembly of materials by homogeneous or heterogeneous joints (welding, bonding, mechanical assembly). Mechanical and environmental resistance of joints.

Content

Keywords

Welding, brazing, adhesives, mechanical joining, polymers, ceramics, metals

Learning Prerequisites

Recommended courses

Polymères, structures, propriétés, MSE-230, MX, Plummer

Materials mechanics, MSE-205, MX, Bourban

Deformation of materials, MSE-310, MX, Logé

Surfaces and interfaces, MSE-304, MX, Ceriotti

Important concepts to start the course

Basic physics and chemistry, simple mechanics

Learning Outcomes

By the end of the course, the student must be able to:

• Describe the basic pricinples of the different joining methods
• Recognize specific characteristics of joints in the different classes of materials (metals, ceramics and plastics)
• Explain the advantages and disadvantages of different joining techniques
• Perform simple structural analysis of mechanical joints
• Discriminate between different classes of adhesives and their applications
• Choose the best joining method for a given application
• Choose the best joining method for different materials
• Analyze the failure of a joint

Transversal skills

• Collect data.
• Make an oral presentation.
• Access and evaluate appropriate sources of information.

Teaching methods

Ex cathedra, seminars, workshop demonstration, exercises

Expected student activities

Attendance at lectures and workshop demonstration, participation in exercises

Assessment methods

Intermediate tests on metals and ceramics and polymers + presentation of a case study. The final mark is the average of the average mark for the tests and the mark for the case study (which hence counts for 50 % of the overall mark)
