Welding Vocab 2

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. National Electrical Manufaturers Association






2. An aperture or hole opening into a bodily cavity

21. Of or relating to or containing iron






22. Threshold Limit Value (TLV) of a chemical substance is a level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects.






23. 30% of the heat is concentrated in the workpiece; 70% of the heat in concentrated in the tungsten electrode; Shallow penetration; Wide weld area; used only for welding thin sheet metal where low current is sufficient.






24. The act of splashing a (liquid) substance on a surface






25. Steel whose characteristics are determined by the amount of carbon it contains
