SHS2 Manufacturing Engineering · Semester 2, Week 13
Manufacturing Processes
Lesson notes
Learning Objectives
Indicator: 2.3.2.LI.1 - Identify and explain the difference between non-permanent and permanent joining processes.
By the end of the lesson, learners can:
- Define permanent and non-permanent joining processes in their own words and give at least two examples of each.
- Sort a collection of joined components into permanent and non-permanent joints, stating the joining process used for each.
- Explain the key differences between permanent and non-permanent joining processes, including reversibility, strength, cost, and typical applications.
- Justify why a specific joining process (e.g., welding, bolting) is more suitable than another for a given manufacturing situation.
- Present their group findings on permanent and non-permanent joints to the class, using appropriate technical vocabulary.

Exemplars (from the NaCCA curriculum)
Collaborative Learning: Learners in mixed-ability groups bring to class components that have been joined together and separate them into components with permanent joints and those with non-permanent joints. Learners identify the joining processes used in the permanent joints (e.g., welding, soldering, brazing, or adhesive bonding) and non-permanent joints (e.g. mechanical fastening with screws, bolts, and nuts) and explain the difference between these joining processes to the class. Teaching and Learning Materials: - Fasteners such as Screws, bolts, and nuts - Welding facilities Assessment (2.3.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 3 Strategic reasoning.
