General Education Information Approved College Associate Degree GE Applicability CSU GE Applicability (Recommended-requires CSU approval) Cal-GETC Applicability (Recommended - Requires External Approval) IGETC Applicability (Recommended-requires CSU/UC approval) Articulation Information Methods of Evaluation Objective Examinations Example: 1. Students will take a multiple choice test on welding symbols. Standard Grading Projects Example: 1. At the start of assigned project, the student will demonstrate a material layout. 2. During the assembly of assigned project, the student will perform fit up steps and tacking procedures. Grading based on industry standard. Skill Demonstrations Example: 1. Students will demonstrate the ability to safely weld in the vertical up and vertical down positions. 2. Student will perform an open groove welding test. 3. Student will demonstrate settings used for various welding modes in GMAW. Grading is based on industry standard. Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: With instructor demonstration and oversight, students will apply various welding techniques using Short Circuit, Globular, Spray, and Pulsed Spray Transfers. Following class lecture, video presentation, and lab demonstration, instructor will supervise while students practice with flux cored, metal cored and solid alloys. Lecture: 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 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.
