Sun, May 14, 2017, 1:00 PM – Sun, Jun 4, 2017, 3:30 PM EDT
Session 1: Sunday, 5/14/17, 1 - 3:30pm
Session 2: Sunday, 5/21/17, 1 - 3:30pm

Session 4: Sunday, 6/4/17, 1 - 3:30pm
One of the great things about the TIG process is its versatility-- it can be used to weld almost any metal, and in fact switching from one material to another takes mere seconds. This class will cover welding technique and best practices for stainless steel and aluminum alloys, combining insights on welding technique, welding engineering & design, fabrication practices, and welding inspection.
NOTE: This is NOT an introductory class. Take Skunk’s Introduction to TIG class before this one, or email the instructor at email@example.com to ask whether this is a good choice for you. This is an intermediate level class, with an intentionally small class size and plenty of contact hours to give you time to practice more challenging skills.
Includes a materials fee to cover filler metals, tungstens, gloves, coupons, gas lenses, and other consumables.
Each session we’ll cover one major topic:
Troubleshooting TIG issues
- Distortion issues
- Cleaning issues
- Gas flow issues
- Tungsten issues
- Arc starting issues
- Bead shape issues
Pulse TIG (GTAW-P)
- Why use pulse TIG?
- Minimize distortion
- Increase travel speeds
- Make gappy/loose fitups easier & faster
- Improve bead appearance (“stack of dimes” look)
- As a training aid for filler metal addition rates
- How to set pulse TIG parameters
- The shiny rainbow colors
- Weldability of stainless steel alloys
- Challenges of stainless welding
- Tungsten alloy selection, sizing, and preparation
- Filler metal selection
- Weldability of aluminum alloys
- Challenges of aluminum welding
- Machine settings for aluminum
- Strength changes in welded aluminum (more here)
- Tungsten selection, sizing, and preparation
- Filler metal selection, including a new option, ER4943
- Proper pre-weld cleaning practices
Asylum’s “Introduction to TIG” class or similar experience. You should have at least a few hours of TIG experience. Send a message via this event or email elabowitz at gmail dot com if you have questions. This class is NOT a good choice if you have only an hour or two of TIG experience. Students must be at least 18 years old.
A $100 materials fee is included in the class price: All materials will be provided by the instructor including stainless and aluminum.
What to Bring/Wear:
Please dress appropriately for the metal shop: long-sleeved organic materials (cotton or wool), tie back long hair, close-toed shoes, and no dangly jewelry/accessories/sleeves/straps.
IF YOU WEAR GLASSES, INCLUDING READING GLASSES: BRING YOUR GLASSES! Welding is extremely detail-oriented work.
If you own a welding hood, please bring it.
