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






2. 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.






3. 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.






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






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






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






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






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






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






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






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






12. Fastening firmly together






13. 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






14. Possible to burn






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






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






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






18. Air conditioning; alternating current






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






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






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






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






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






24. 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.






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






26. Direct Current






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






28. Of or relating to very low temperatures






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






30. Containing little or no iron






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






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






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






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






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






36. A cloud- like area where welding fume collects






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






38. Of or relating to or containing iron






39. In constant change






40. 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






41. A movement forward






42. Compliance for Safety Glasses






43. Put into a certain place or abstract location






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






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






46. 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.






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






48. Lack of connection of continuity






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






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