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.

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






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






28. 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.






29. Air conditioning; alternating current






30. A movement forward






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






32. 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.






33. An aperture or hole opening into a bodily cavity






34. Direct Current






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






36. National Electrical Manufaturers Association






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






48. 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






49. An affix that added in front of the word






50. 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.
