            Methods of Instruction

            • Laboratory
            • Lecture/Discussion
            • Distance Learning

            Lab:

            1. With instructor demonstration and oversight, students will apply various welding techniques using Short Circuit, Globular, Spray, and Pulsed Spray Transfers.
            2. Following class lecture, video presentation, and lab demonstration, instructor will supervise while students practice with flux cored, metal cored and solid alloys.

            Lecture:

            1. Lecture and interpersonal group discussion on the various types and applications of welding modes, such as FCAW-G Flux Cored Welding with dual Shielding vs FCAW-S Flux Cored Welding self shielding.

            Distance Learning

            1. Instructor will use slide show presentation, instructor created video, or lecture presentation on a learning platform to teach about best safety practices in the for personal protective equipment, the weld lab environment, and/or tools & equipment. Students will be given a scenario and expected to list the best safety practices that should be employed and explain why they should be used. Students will submit the assignment via text entry, file upload, video or audio recording.

            Typical Out of Class Assignments

            Reading Assignments

            1. The student will read chapter from the course text on GMAW transfer modes of short circuit, globular, spray transfer, and related materials and be prepared for classroom discussion. 2. The student will look up the welding parameters for the different wire diameters and compositions to become familiar with the correct machine settings to use.

            Writing, Problem Solving or Performance

            1. The student will create a report of the different chemical compositions from the reading assignments welding procedures for Flux Cored, Metal Cored and other solid alloys. 2. Students demonstrate their performance of each of the various welds, such as pulsed spray transfer, on lab assignments during each class meeting.
