Location:
635 Avenue of the Americas, New York, NY.
Dates:
December 1994 - March 2003.
Learner Outcomes:
Course 1: Describe procedures for personal safety, burn prevention, fire prevention, and safe handling and use of oxy-acetylene equipment; identify metals by spark test, magnetic test, physical appearance and physical weight; describe American Welding Society classification of mild steel rods; set up welding equipment and make necessary flame adjustments to produce fillet welds on Tee, Lap and Butt joints in the flat and horizontal positions with and without the use of a filler metal; perform brazing in the flat and horizontal positions on Tee and Corner joints; perform manual and automatic flame cutting; describe the process of identifying quality welds. Course 2: Use AC, AC/DC, and transformer/rectifier AC/DC welding machines to produce multi-pass fillet welds on a Tee joint in all positions (Vertical, Overhead, Flat, and Horizontal) using E-6011 and E-6013 electrodes; identify types of joints, types of welding machines, the currents they produce, and determine the difference between reverse and straight polarity; use a pedestal grinder, chipping hammer, wire brush and pliers, and personal safety equipment.
Instruction:
Course 1: Introduction to oxy-acetylene welding; oxy-acetylene equipment; set-up procedures for oxy-acetylene welding; oxy-acetylene flame adjustment; fusion without filler metal; fusion welding with filler metal; fillet welding lap joint horizontal position; fillet welding horizontal position corner joint; flame cutting; brazing; safety procedures. Course 2. Basic shielded metal arc welding; arc welding equipment, terms and definitions; power sources for arc welding; surface welding; functions of electrode coatings and heat treatments; fillet welding horizontal position 2F; mechanical properties of metals and quality oxy-acetylene cutting; fillet welding vertical position 3F; compositions of electrode coatings; fillet welding overhead position 4F.
Credit recommendation:
Courses 1 and 2: In the lower division baccalaureate/associate degree category, 5 semester hours (2 lecture, 3 shop) in Welding Technology, Industrial Technology, Construction Technology, Vocational Technology, as an elective in Educational Technology, or as a technical elective in Mechanical Technology (12/99). NOTE: Credit is recommended only upon the completion of both courses.
