       Credits: 4 (3 lecture; 2 lab)

II.    Prerequisite


III.   Course (Catalog) Description

Course covers basic electric arc, oxy-fuel, gas metal arc, and gas tungsten arc welding processes. Safety procedures required to set up and shut down welding equipment for the various processes. Hands-on experience includes practice with the four welding systems using various thickness materials. Industrial standards and American Welding Society (AWS) standards for quality are discussed.

IV.   Learning Objectives

  1. Produce quality welded joints in the flat position utilizing oxy-acetylene welding , Shielded Metal Arc Welding(SMAW), Gas Metal Arc Welding (GMAW), and Gas Tungsten Arc Welding (GTAW)
  2. Demonstrate the safety practices of a variety of welding processes
  3. Identify the terms and definitions of a variety of welding processes
  4. Identify the careers in the welding field and the employability skills needed for them
  5. Identify safe welding practices and procedures conforming to American Welding Society (AWS) Z 49 standards.
  6. Demonstrate practical knowledge of making welds with all types of mild steel   electrodes, arc air gouging and the welding of mild steel in all positions in a safe manner.
  7. Interpret both basic and advanced welding fabrications blueprints including: welding symbols, weld testing symbols, structural steel shapes, and welding specifications.
  8. Document advanced knowledge and techniques for the safe and successful operation of gas tungsten welding, shielded metal arc welding, gas metal arc welding, and oxy fuel gas welding.
  9. Perform an American Welding Society (AWS) 1G with a backing strip test or 3G with an open root.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

X.    Methods of Evaluating Student Progress

  1. Carefully check your Assignment Sheets for specific exercises for your course. Consult with the instructor before beginning each exercise.
  2. Complete the text book reading and workbook written exercise and have them checked with the instructor.
  3. All courses have unit pre and post tests and Mid-term exam. All unit tests must be completed before lab work begins. Only post test scores will be used for grading.
  4. Your final grade is calculated as the total points of the following:
    1. Score on all Unit Post Tests
    2. Completed Activities Exercises from your workbook
    3. Mid-Term test score
    4. Final Test Score
    5. Workbook exercises

XI.   Other Course Information
