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






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






3. Containing little or no iron






4. A cloud- like area where welding fume collects






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






6. Compliance for Safety Glasses






7. 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.






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






9. 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






10. Lack of connection of continuity






11. Fastening firmly together






12. Of or relating to very low temperatures






13. 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.






14. 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.






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






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






17. Direct Current






18. 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.






19. In constant change






20. National Electrical Manufaturers Association






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






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






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






24. A permit system for Hot Work is required by the State Fire Prevention Code and OSHA






25. Materials or liquids that catch fire easily






26. A movement forward






27. Air conditioning; alternating current






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






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






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






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






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






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






34. 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.






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






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






37. To solder (two pieces of metal) together using a hard solder with a high melting point.






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






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






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






41. Department of Transportation






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






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






44. American Welding Society






45. Possible to burn






46. An affix that added in front of the word






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






48. Put into a certain place or abstract location






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






50. Any of the chemically inert gaseous elements of the helium group in the periodic table
