UNIT OBJECTIVES: Upon completion of this unit, students will be able to:

   1. Pass a safety test and demonstrate proper use of arc welding 
       equipment.

   2. Strike and maintain an arc correctly.

   3. Be familiar with the American Welding Society (AWS) classification 
       system for electrodes.

   4. Select various sizes and types of electrodes and correctly adjust the 
       current setting for each application.

   5. Identify four basic welding joints and demonstrate the application of 
       each in the flat position, using AC and DC equipment.

   6. Control distortion in arc welding.

   7. Test welds for quality and strength.

   8. Construct a project requiring at least three different welds.

   9. Identify career opportunities in the welding industry.

  10. Change lens and head gear on a helmet.
