Through the methods of lecture/discussion, films, and demonstration, the student will be introduced to electric and gas welding and cutting. The student will be provided with the fundamental principles of joining ferrous and non-ferrous metals, welding and cutting processes, equipment operation, and safety procedures. The student will develop the skills to safely use oxy-acetylene cutting equipment and the skills to use the Shielded Metal Arc Welding (SMAW) process in all positions. Training will also be included in plasma cutting and air carbon arc gouging with an introduction to shop fabrication equipment.
The student will be taught the operation of AC transformers and DC motor generator arc welding sets, welding polarities, heats and electrodes for use in joining various metal alloys by the arc welding process. The student will acquire the ability to weld in the flat and horizontal positions with a variety of electrodes. The student will acquire manipulative skill, and demonstrate his/her ability by passing an ASME (American Society of Mechanical Engineers) Sec. IX welder qualification test in the 2G position.
The student will gain skills welding in the vertical and overhead positions. The student will also be required to pass an ASME welder qualification test in the vertical (3G) and overhead (4G) positions.
The student will acquire the ability to set up GTAW equipment and the skills to prepare tungsten electrodes for both ferrous and non-ferrous metals. The student will develop welding skills in various positions and with a variety of base metals.
Studies techniques and practices of testing welded joints through destructive and non-destructive testing. (Prerequisites WEL 123 and WEL 160). Lecture 2 hours. Laboratory 6 hours. Total 8 hours per week.
Through the use of lab experiments the student will be able to understand the physical changes that take place in metals during and after welding. The student will also perform basic heat treating experiments to gain an understanding of their effects on steels.
The student will be able to set up and adjust gas metal arc equipment for welding in all positions. The student will gain skills with both solid and cored wire. The student will also pass an ASME welder qualification test in at least the horizontal and vertical positions.
The student will be assigned independent studies to complete for the purpose of gaining the abilities to fabricate, solve problems, and further develop the skills learned in the prerequisite welding courses. The student will also design a special welding course covering a special skill area, e.g., GTAW pipe welding, GMAW pipe welding, etc. The student will pass welder qualification tests in SMAW, GMAW, FCAW, GTAW.
Teaches principles and practices of accident prevention, analysis of accident causes, mechanical safegaurds. fire prevention, housekeeping, occupational diseases, first aid, safety organization, protectionequipment and general safety principles and promotion. Lecture 3 hours per week.
Teaches the application of basic principles, visualization, orthographic projection, detail of drafting shop processes and terminology, assembly drawings and exploded views. Considers dimensioning, changes and corrections, classes of fits, tolerances and allowances, sections and conventions in blueprint reading. (Credit will not be awarded for both CAD 161 and DRF 161.) Lecture 1 hour. Total 1 hour per week.
Teaches computer aided drafting concepts and equipment designed to develop a general understanding of components and operate a typical CAD system. Lecture 1 hour. Labratory 2 hours. Total 4 hours per week.
