INWE 45020 - Start Arc and Run Beads with GTAW

0.42 CR
Rigid attention to detail and procedure is of extreme importance in TIG welding. Errors due to carelessness may prove to be very expensive. For instance, failure to turn on the cooling water usually results in the destruction of the torch as well as the cable and hose assembly. Striking an arc with the machine set for normal amperage but with the polarity selector on DCRP will result in the destruction of the electrode and usually the collet holder and collet. In this module, the welding student will learn how to start an arc and run stringer beads on aluminum using TIG equipment.

Course Learning Outcomes:
  1. Demonstrate the knowledge of the gas tungsten arc welding process by correctly setting up a GTAW system, including voltage, amperage, shielding gas and all variables.
  2. Identify various weld defects and their characteristics.
  3. Execute correct metal preparation for GTAW.
  4. Describe the fundamentals of Gas Tungsten Arc Welding (GTAW).
  5. Identify the GTAW process in comparison to other arc welding processes.
  6. Identify the basic GTAW electrode numbering system as established by the American Welding Society.
  7. Produce various weld beads, flat position welds.
  8. Produce GTAW Aluminum welds in the flat position.
  9. Produce GTAW Aluminum welds in all positions.
