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.

7. Visible particles of matter suspended in the air - such as mist or smoke






8. To cause to die or lose consciousness by impairing normal breathing - as by gas or other noxious agents; choke; suffocate; smother.






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






10. An aperture or hole opening into a bodily cavity






11. 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.






12. The strength of material expressed as the greatest longitudinal stress it can bear without tearing apart






13. A movement forward






14. To solder (two pieces of metal) together using a hard solder with a high melting point.






15. 70% of the heat is concentrated in the workpiece; 30% of the heat is concentrated in the tungsten electrode; Deep penetration; Narrow weld area; welding other materials than aluminum or magnesium






16. A conductor used to make electrical contact with some part of a circuit
