In our Basic Pipe Welding class, students learn a new welding process, gas tungsten arc welding (GTAW), and build upon their knowledge of SMAW to advance their pipe welding skills. GTAW is a process that requires skill and precision to produce high quality welds. During the process, a non-consumable tungsten electrode conveys the electric arc to the base metal, melting the base metal and the filler metal as it is manually delivered into the weld pool. A shielding gas is used to protect the weld from environmental contamination. Students also build upon skills learned in previous welding classes.

  • Practice GTAW to execute basic root welds on pipe coupons.
  • Use SMAW to perform cap and fill welds in 2G and 6G positions.
  • Execute 2G and 5G welds.
  • Follow basic pipe welding technical drawings to apply mechanical and thermal beveling processes to cut pipe coupons and bevel pipe ends.
  • Practice uphill welding and traveling around the pipe while welding in several positions.
  • Select appropriate filler metals for the project using basic metallurgy principles.
  • Mechanical and visual testing techniques.
