Students will use a variety of resources including text books, web sites and plans of procedures, to enable them to create a welded steel product in the school workshop.
 
Through the use of a hot list students will learn the basics of differant welding processes. Resistance spot, stick electrode and MIG processes will be covered. This activity should build a basic understanding to prepare a student for a hands-on experiance on the shop floor.
 
IMPLEMENTATION

This activity is part of the eighth grade metalworking curriculum at RMS and will prepare a student for laboratory activities related to welding mild steel in the RMS shop.
 
Students will begin by collaboratively researching tools and techniques in the textbook and online after being given a plan sheet and a plan of procedures. Then groups will begin their laboratory experience by creating a product in the school shop. Although the students will be working in group, each student should fabricate a product. The instructor will demonstrate each process to various groups before they begin that particular process.
