If you’re interested in becoming a certified TIG welder, you first need to pass a certification exam and interview. This requires a thorough understanding of the techniques and materials used, as well as the practical skills necessary to complete a range of projects. Here are some helpful tips to review before your test.

How to Prepare for a TIG Welding Exam

1. Study Your Metals & Techniques

You can use TIG welding on a variety of metals, including tungsten, aluminum, and titanium. To produce clean welds, you need to be comfortable working with all materials.

You may also need to switch up your technique based on the requirements of the practical exam. For instance, you might be asked to weld in a space that provides very little clearance or visibility. Studying the properties of different metals and how they affect handling will help you prepare for every possible situation.

2. Keep Tools Clean

To pass the test, you need to produce welds that show no sign of contamination. If there are unapproved substances on your metals or electrode, it will be visible in the result.

Avoid problems by cleaning the base metals thoroughly with a wire brush and degreaser. As you weld, keep clean electrodes near your station so you can switch yours out if it becomes contaminated.

3. Find a Comfortable Position

To produce the cleanest weld possible, you need to keep your hands steady. It’s difficult to do this if you’re in an uncomfortable or unfamiliar position.

Prior to the test, practice your technique in a variety of positions, always making sure your hands are supported so they don’t slip or waiver. During the exam, try to mimic the positioning that worked best for you.
