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






3. Materials or liquids that catch fire easily






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.






5. An affix that added in front of the word






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






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






8. Lack of connection of continuity






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






10. 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.






11. Cut - notch or groove; quantity of something cut at the same time






12. Put into a certain place or abstract location






13. Air conditioning; alternating current






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






15. 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.






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






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






18. An aperture or hole opening into a bodily cavity






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






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






21. National Electrical Manufaturers Association






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






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






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






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






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






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






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






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






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






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






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






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






34. Direct Current






35. Of or relating to very low temperatures






36. 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.






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






38. Possible to burn






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






40. 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






41. 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.
