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.

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






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






4. The difference in electrical charge between two points in a circuit expressed in volts






5. 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






6. An affix that is added at the end of the word






7. A vehicle used to haul goods ; especially : a strong cart or wagon without sides






8. Containing little or no iron






9. Materials or liquids that catch fire easily






10. Compliance for Safety Glasses






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






12. American Welding Society






13. 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






14. Of or relating to or caused by a toxin or poison






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






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






17. Possible to burn






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






19. 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.






20. Fastening firmly together






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