Free Welding Aptitude & Entrance Practice Test
Math, mechanical reasoning, and reading — the skills welding programs and apprenticeships test before they take you.
Built for welding apprenticeship & program applicants
Going union in the pipe trades?
This test is good practice, but I built a separate app for the UA battery — same founder, built for your trade.

Welding programs and apprenticeships use an entrance aptitude test to confirm you have the math and mechanical foundation for the trade — measurement, heat, and reading technical instructions. This free practice test mirrors that format so you know where you stand before test day.
Your trade has its own app
PipePrep AI — built for the UA pipe trades battery
Pipefitters and steamfitters weld for a living, so the UA pipe trades are the closest union route — though boilermakers and ironworkers weld too, and they run their own programs. Worth knowing either way: the UA battery has no welding section. It tests math, reading, mechanical reasoning and spatial visualization.
Straight up: I’m an IBEW journeyman electrician and a pre-apprenticeship instructor — not a UA member. What I know cold is how union selection works, and that part is the same across the building trades. The test content is not, which is why it’s a separate app.

What is on a welding aptitude test?
Welding entrance and aptitude tests measure math (fractions, measurement, basic algebra), reading comprehension of technical instructions, and mechanical reasoning (heat, expansion, leverage, gears). Some programs add spatial/blueprint reading. The goal is to confirm you can handle the math and reading the trade requires.
What math do welders need?
Fractions and measurement math come up constantly — reading a tape measure, calculating cut lengths, and material thickness. You also need percentages, ratios, and basic algebra. A calculator usually isn’t allowed on the entrance test, so mental math speed matters.
How should you prepare?
Drill fractions and measurement first, then practice mechanical-reasoning concepts like heat expansion and leverage. Use this free practice test to find your weakest section and focus there.
Frequently Asked Questions
Is this an official welding test?
This is a free practice test that mirrors the format welding programs and apprenticeships use for entrance — math, reading comprehension, and mechanical reasoning. Exact questions vary by program, but the sections and difficulty are representative.
What is on a welding entrance test?
Math (fractions, measurement, percentages), reading comprehension of technical passages, and mechanical reasoning (heat, expansion, gears, leverage).
