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. Possible to burn






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






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






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






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






8. 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






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






10. An affix that added in front of the word






11. 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






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






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






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






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






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






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






18. 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.






19. Of or relating to very low temperatures






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






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






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






23. 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.






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






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






26. In constant change






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






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






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






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






31. Compliance for Safety Glasses






32. Department of Transportation






33. Air conditioning; alternating current






34. National Electrical Manufaturers Association






35. An aperture or hole opening into a bodily cavity






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






37. 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.






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






39. Direct Current






40. American Welding Society






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






42. Fastening firmly together






43. Lack of connection of continuity






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






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






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






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






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






49. Containing little or no iron






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