About this practice suite
This suite prepares candidates for welding selection in the skilled trades and apprenticeships sector with 4 skill areas: technical reasoning, mechanical comprehension, safety judgment and spatial reasoning. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.
Skills this suite practises
- Technical reasoning — Applied technical principles, diagrams, tools, systems, measurements, and troubleshooting.
- Mechanical comprehension — Forces, motion, gears, pulleys, levers, fluids, pressure, and basic machines.
- Safety judgment — Hazard recognition, safe sequencing, escalation, and risk controls.
- Spatial reasoning — Rotation, folding, views, orientation, maps, and three-dimensional visualization.
Sample questions from the guided bank
Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.
Before replacing a MIG contact tip, what is the safest first action?
- A. Increase wire-feed speed
- B. Isolate the welder from its power source
- C. Open the shielding-gas valve fully
- D. Strike an arc on scrap
What does a welding procedure specification primarily establish?
- A. The invoice price of filler metal
- B. The approved variables and method for making the weld
- C. The daily production target
- D. The paint colour after fabrication
Practice modes and timing
Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
| Mode | Questions | Duration | Start |
|---|---|---|---|
| Guided practice | 10 | 15 minutes | Open |
| Timed mini-test | 12 | 18 minutes | Open |
| Full simulation | 30 | 45 minutes | Open |
