Catalog Description

Formerly known as WELD 10
Hours: 72 (18 lecture, 54 laboratory)
Description: History and development of joining metals, metalworking, and gas welding methods. Students will learn the fundamentals of Oxyacetylene gas welding and gain manipulative skills that will prepare them for Gas Tungsten Arc Welding. Creativity, gas welding and fabrication techniques will be utilized to complete a student project. (CSU)

4. Demonstrate use of Oxygen and Acetylene cylinders, regulators, check valves, torches, tips and hoses.
5. Apply and demonstrate the Oxy-Acetylene (Gas) Welding practice in flat, horizontal, and vertical position.
6. Operate drilling equipment, such as the hand drill and drill press, as well as metal hole punching tools and machines.
7. Use Tap and Die to thread a hole and fit bolt.
8. Demonstrate proper use of metal removal equipment (cold), such as hand file, and hot such as a bench grinder, hand held grinder to blend and finish metal.
9. Use and relate the terms used in this course for the metalworking and welding applications.
10. Identify and perform the basic math functions required to construct the assigned lab project; addition and subtraction of fractions and mixed numbers, multiplication and division of fractions and mixed numbers in use with measuring instruments, such as tape measure, slide square, and carpenter's square.
11. Complete assigned project following provided drawings and instruction along with the safe and proper use of the tools machines, and welders.

          Methods of Instruction

          • Laboratory
          • Lecture/Discussion
          • Distance Learning

          Lab:

          1. With instructor demonstration and oversight, students will operate various types of metal working equipment.
          2. With instructor demonstration and oversight, students will develop Oxy-Acetylene welding skill sets.
          3. Following class lecture, video presentation, and lab demonstration, student will practice manipulative skills in the welding process application.

          Lecture:

          1. Lecture and small group discussion of the uses of metal in the modern day.

          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. Read about the history of metals before the 20th century in print and web-based material. Be prepared to discuss in class the development of welding as it applies to the Industrial Revolution. 2. Read text chapter on Oxy-Acetylene welding, equipment and components and be prepared to discuss. Compare with contemporary practices.
