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






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






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






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






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

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






9. American Welding Society






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






11. Department of Transportation






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






13. 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.






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






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






16. 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






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






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






19. In constant change






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






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






22. A cloud- like area where welding fume collects






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






24. Materials or liquids that catch fire easily






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






26. Of or relating to very low temperatures






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






28. Lack of connection of continuity






29. Direct Current






30. Of or relating to or containing iron






31. Put into a certain place or abstract location






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






33. 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.






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






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






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






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






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






39. 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.






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






41. 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.






42. National Electrical Manufaturers Association






43. Air conditioning; alternating current






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






45. 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






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






47. Fastening firmly together






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






49. These are areas where your hands can become trapped or mashed between two objects






50. A movement forward
