Review: Review safety covered in class. Overall Objective: See Cover Sheet

1. Suit up all students in required safety gear as well as assign them booths. They will work in those booths with their chosen partners for the unit.

2. Explain to the students where the welding rods will be kept as well as the metal they will be using to weld. 3. Demonstrate a few beads to the students exhibiting too

high amperage, too high an arc length as well as suitable amperage and arc length.

1. Review safety standards and expectations with students by going over safety test with them.

a. Have students complete safety portion of packet and review with them.

2. If there is remaining time, have students work with myself or my cooperating teacher to begin welding and to answer any questions they may have.

3. Be sure that by the end of the period, the students have cleaned up their booth and work area and that is it inspected by myself or my cooperating teacher.

4. As the students progress in their experience with welding, be sure to place beads for them to compare their progress with, and show them how you do them.
