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. The distance from which the electrode is from the base metal while you're welding.






2. To treat - combine - or impregnate with carbon - as when casehardening steel.






3. Of or relating to or containing iron






4. Used to achieve better hardenability - which in turn improves its other mechanical properties. They are also used to increase corrosion resistance in certain environmental conditions. Difficult to weld.

6. Procedure To prevent the accidental release of energy to equipment being cleaned -






7. National Electrical Manufaturers Association






8. A permit system for Hot Work is required by the State Fire Prevention Code and OSHA






9. Of or relating to very low temperatures






10. The property of being porous;being able to absorb fluids






11. A movement forward






12. American Welding Society






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






14. A widely used abbreviation for Material Safety Data Sheet. A MSDS contains details of the hazards associated with a chemical - and gives information on its safe use.
