WELD 0005B. Intermediate Shielded Metal Arc Welding (SMAW) - Career Path

Units: 2
Formerly known as WELD 25
Prerequisite: Completion with grade of "C" or better or concurrent enrollment in WELD 5A
Hours: 72 (18 lecture, 54 laboratory)
Students expand on knowledge and skills gained to perform structural plate welding using Shielded Metal Arc Welding (SMAW or Stick). Oxyacetylene Cutting (OAC) and Air Carbon Arc Cutting (CAC-A) are also performed. Intended as an intermediate level welding course for students following a career path in structural or pipe welding fields. Students are advised that WELD 5A and WELD 5B can be taken at the same time. (not transferable)

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 Classroom Discussions Example: Instructor facilitates group discussion on the SMAW open groove techniques for critical out of position welding, with lab application evaluation. Students are evaluated based on participation. Objective Examinations Example: Examination of the definitions of weld discontinuities and interpretation of welding symbols. Students will be evaluated based upon the accuracy of their answers. Skill Demonstrations Example: Lab assignments in each welding position and joint configuration covered in this course. Students' work is evaluated and graded based on industry and AWS weld quality standards. Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: With instructor demonstration and oversight, students will apply techniques of position welding to complete lab assignments. Following class lecture, video presentation, and lab demonstration, instructor will supervise student practice in honing manipulative skills in each welding process application. Lecture: Instructor will lead a lecture and group discussion on the SMAW open groove techniques for critical welding. 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.
