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.

10. In constant change






11. An affix that added in front of the word






12. 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






13. Containing little or no iron






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






15. National Electrical Manufaturers Association






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






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






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






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






20. 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.






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






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






23. Direct Current






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






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






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






27. Possible to burn






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






29. 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.






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






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






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






33. Air conditioning; alternating current






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






35. Compliance for Safety Glasses






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






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






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

41. Materials or liquids that catch fire easily






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






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






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






45. 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.






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