Career Spotlight: Welder (Ages 14-18)

What are the different types of welding?

Welding can be done in many different ways. Here are some of the types of welding used at NASA:

• Arc Welding: Uses electricity to melt metals and fuse them together. There are many types of arc welding, including TIG and MIG welding, described below.
• Tungsten Inert Gas (TIG) Welding: Uses a protective gas like argon or helium to keep the metal from reacting with air. TIG welding doesn’t leave behind splatter or residue, giving a clean, precise weld.
• Metal Inert Gas (MIG) Welding: While not as clean and precise as TIG welding, is used for fast, strong welds on thicker materials, like sheet metal.
• Laser Welding: Enables welders to create tiny, perfect joints for delicate components.
• Ultrasonic Welding: Uses sound and friction to create a solid-state bond between layers of metal.

How can I become a welder?

After graduating from high school, there are a couple of pathways to choose from. You can pursue an associate’s degree in welding, typically a two-year program available through community colleges and technical schools. Another option is to obtain a certificate from a vocational school or trade school. An apprenticeship during or after this training is often the next step toward a career as a professional welder.

How can I start preparing today to become a welder?

Taking a welding class at your high school or local college is a great way to find out whether it’s a skill you enjoy. Research welding degrees and programs at colleges and schools to determine which one(s) fit your needs and interest. It’s also a good idea to research job vacancies to learn what employers are looking for. Finally, seek out opportunities for hands-on experience to help you practice and improve your welding skills.

Once I tried it, I really, really enjoyed it. There’s just something about creating something with your hands. It gives you a sense of accomplishment.

Advice from other NASA welders

• “Building your knowledge in math and science is always a helpful tool, as you’ll need to understand measurements, geometry, and materials.” – Spencer Wells, engineering technician, Kennedy Space Center
• “One of the best ways to set yourself up as a welder is by attending a vocational school for welding, and then working in an apprentice/internship to gain work experience and training.” – Enricque Lee, tool and die apprentice, NASA’s Glenn Research Center
