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






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






3. An affix that added in front of the word






4. Lack of connection of continuity






5. An aperture or hole opening into a bodily cavity






6. 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.






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






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






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






10. Of or relating to very low temperatures






11. Fastening firmly together






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






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






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






15. Of or relating to or containing iron






16. A mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten






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






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






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






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






21. 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.






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






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






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






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






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






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






28. A movement forward






29. National Electrical Manufaturers Association






30. 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.






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






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






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






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






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






36. 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






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






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






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






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






41. Shield consisting of an arrangement of metal mesh or plates designed to protect electronic equipment from ambient electromagnetic interference






42. In constant change






43. Department of Transportation






44. 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
