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. 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.






2. A metal added in the making of a joint through welding - brazing - or soldering.






3. Of or relating to sytems made up of combination of letters and numbers






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






5. American Welding Society






6. A metal joint formed by softening with heat and fusing or hammering together






7. The surface of a material in contact with another to which it is or will be joined

13. A phenomenon associated with surface tension and resulting in the elevation or depression of liquids in capillaries






14. Department of Transportation






15. A condition that occurs when the arc does not follow its intended path from the electrode to the workpiece. Arc blow can cause undesirable weld beads.






16. A government agency in the Department of Labor to maintain a safe and healthy work environment






17. A low- carbon steel containing sufficient iron oxide to give a continuous evolution of carbon monoxide while the ingot is solidifying - resulting in a case or rim of metal virtually free of voids. Sheet and strip products made from rimmed steel ingot






18. An affix that added in front of the word

26. Of or relating to or containing iron






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






28. Of or relating to very low temperatures






29. 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.






30. The basic unit of electric current adopted under the Systeme International d'Unites






31. Direct Current

33. The American Conference of Governmental Industrial Hygienists (ACGIH); develops TLVs and BEIs as guidelines to assist in the control of health hazards
