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. American Welding Society






2. 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.






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






4. Fastening firmly together






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






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






8. Planar weld discontinuity in which fusion does not occur between the weld metal and base metal or between adjoining weld beads






9. Possible to burn






10. 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.






11. Of or relating to or containing iron






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






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






14. A set of rules or principles or laws (especially written ones)






15. A homogeneous solid that can exist over a range of component chemicals






16. Direct Current






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






18. 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.






19. Materials or liquids that catch fire easily






20. Discontinuity in a groove weld in which the weld metal doesn't extend through the joint thickness.






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






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






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






24. American National Standards Institute; the governing body for standards in the U.S.






25. Containing little or no iron






26. PSI (pounds per square inch ) a unit of pressure equal to 6.895 x 10 Pa or 51.71 torr






27. 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






28. Of or relating to very low temperatures






29. 'kilo- pound[- force] per square inch') is 1000 psi






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






31. In constant change






32. Cut away material from the underside of (an object) so as to leave an overhanging portion in relief






33. A movement forward






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






35. The union of diverse things into one body or form or group






36. (physical chemistry) a fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors






37. Department of Transportation






38. Compliance for Safety Glasses
