Aims
This module aims to equip the students with the necessary background for understanding the selection and control of appropriate joining technologies for industrial applications with emphasis on welding, adhesive bonding, brazing and soldering.
Outline Of Syllabus
• Surface requirements for joining; surface structure, preparation and selection requirements.
• Solid state joining processes; pressure welding, friction welding, explosive welding, ultrasonic welding, diffusion bonding, resistance welding.
• Brazing and soldering, filler materials and fluxes, heating methods.
• Adhesive bonding; types of adhesive, wetability, surface preparation, joint design.
• Fusion welding fundamentals; heat sources, the electric arc, metal transfer, incomplete fusion, solidification of melts, gas-metal reactions, solubility of gases in metal melts, hydrogen embrittlement, weld decay, porosity.
• Fusion welding processes; oxyacetylene torch, manual metal arc, MIG, TIG, submerged arc, electroslag, laser and electron beam welding.
• Responses of materials to welding; structure of the welded joint, stresses and distortion, solidification cracking, reheat cracking, heat treatments of welds, failure of joints.
• Welding specific material classes; plain carbon and carbon-manganese steels, low alloy steels, stainless steels, copper alloys, aluminium alloys, nickel and nickel alloys, transition welds.
• Design and performance of welded structures; joint design, static and dynamic loading.
• Quality assurance of welds; NDT, control and recording.

Teaching Rationale And Relationship
Lectures convey the underlying engineering science and the approaches required to apply this to the discipline-specific problems identified.
The practical sessions are supervised activities in which the students apply the knowledge that they gain during formal lectures and private study to analyse the microstructure of welded specimens.
Tutorials support the students' private-study in reading around the lecture material and learning to solve the practical engineering problems posed by the Tutorial Questions.
If Covid impacts, all activities will be moved online.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The lectures are designed to assist students in the acquisition of a knowledge base that will facilitate understanding of processes, concepts and analysis methods.
The tutorial sessions are supervised activities in which the students apply the knowledge that they gain during formal lectures and private study to analyse the behaviour of joints.
