Welding II: Steel TIG Class

With Isabel Delgado

This class has suggested but not required prerequisites. See below for details.

Take your welding abilities to the next level and lay down those perfect "stacked dimes" Instagram welds! Often called the pinnacle of welding, the GTAW (TIG) process offers unparalleled precision and control, creating the strong, clean welds required for professional metal fabrication and artistic projects. This hands-on TIG welding workshop demystifies the art of TIG welding, focusing on the torch control, heat management, and filler metal technique required for strong, beautiful joints. This course also covers some of the most common welding joints that any fabricator will experience in the wild. Join this supportive friendly workshop, expand your handy DIY skillset, and connect with a community of fellow makers!

What You’ll Make:

  • TBD (but there will be plenty of time to practice!)

Skills & Concepts You’ll Learn:

  • Fundamentals of the TIG welding process for steel.

  • Setting up a TIG welder: amperage, gas flow, and tungsten preparation.

  • Mastering torch angle, travel speed, and arc length for puddle control.

  • Properly adding filler metal to create a strong, consistent bead.

  • Techniques for creating clean T-joints and corner welds.

  • How steel TIG principles apply to other metals like stainless steel and aluminum.

Equipment & Tools You’ll Learn:

  • TIG welder with foot pedal, TIG torch, tungsten electrodes, filler rods, and various metalworking clamps.

Class Outline:

  1. Prep & Theory: TIG principles, welder setup and safety review.

  2. Demonstration: Instructor shows proper torch technique, puddle control, and adding filler metal.

  3. Hands-On Practice: Students practice laying beads on flat bar to develop muscle memory and control.

  4. Project Fabrication: Students weld their project with instructor guidance.

  5. Wrap-Up: Review of key concepts, troubleshooting common issues, and Q&A.

Other Class Info:

  • Prerequisites: Welding I or other MIG experience is strongly recommended, but not required.

  • Class Capacity: 6 maximum, 3 minimum

  • Materials Provided?: Yes

  • Age Limit: 17+. Guardian required if under 18 (info).

  • Partner Ticket Available?: No

  • Clothing/Equipment Requirements?: Pants, long-sleeved shirts, and closed toed shoes that you don’t mind getting dirty. Fabrics must be natural like cotton or leather - do not wear synthetics as they can melt if a spark comes in contact.
