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. 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






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






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






5. An affix that added in front of the word






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






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






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






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






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






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






12. 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.

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






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






22. 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.






23. Of or relating to or containing iron






24. Possible to burn






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






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






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






28. Lack of connection of continuity






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






30. Direct Current






31. 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.






32. A cloud- like area where welding fume collects






33. National Electrical Manufaturers Association






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