These 23 learning guides are self-instructional packets for 23 tasks identified as essential for performance on an entry-level job in welding. Each guide is based on a terminal performance objective (task) and 1-4 enabling objectives. For each enabling objective, some or all of these materials may be presented: learning steps (outline of student activities) with necessary resources/materials cited, instruction sheet(s), and self-check with answer key. A performance test and/or a written test (with answer key) concludes each guide. Tasks covered in these guides include drilling, cutting, shearing, and punching metal; wire brushing; welding outside corner joints; butt joints, single and multiple pass lap joints, 3 pass and 6 pass "Tee" joints, and vee-bend test plates in horizontal, vertical, and overhead positions; welding with low hydrogen electrodes; finishing metal surfaces; assembling tig and mig torches and preparing to weld with them; welding mild steel, stainless steel, and aluminum with tig equipment; and welding mild steel with mig equipment.
