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






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






3. A movement forward






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






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






6. 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.






7. Cut away material from the underside of (an object) so as to leave an overhanging portion in relief






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






9. 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.






10. 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.






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






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






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






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






15. An affix that added in front of the word






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






17. Department of Transportation






18. Air conditioning; alternating current






19. Containing little or no iron






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






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






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






23. Fastening firmly together






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






25. A cloud- like area where welding fume collects






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






27. American Welding Society






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






29. 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






30. In constant change






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






32. Possible to burn

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






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






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






37. Materials or liquids that catch fire easily






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






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






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






42. Compliance for Safety Glasses

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






47. Lack of connection of continuity






48. 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.






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