Lesson notes

Learning Objectives

Indicator: 1.4.2.LI.3 - Indicate the various applications of gas and electric arc welding

By the end of the lesson, learners can:

Identify at least five real-life applications of gas welding and five real-life applications of electric arc welding from their local environment.
Sort given welding jobs correctly into either gas welding or electric arc welding categories and justify their choices.
Explain why a specific welding process is chosen for a particular application based on the type of metal, thickness of material, and the nature of the job.
Work collaboratively in mixed ability groups to research and present applications of gas and electric arc welding found in their community.
Demonstrate respect for diverse opinions and gender inclusion during group presentations and class discussions.

Exemplars (from the NaCCA curriculum)

Organise the learners into fair mixed ability and gender inclusive groups, task them to effectively research on the specific applications where gas and electric arc welding are used. E.g. Burglar proof for windows, gates, car body repairs, local containers, metal tables and chairs etc.
