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 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.






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






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






4. 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.






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






6. Fastening firmly together

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






13. In constant change






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






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






16. 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.






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






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






19. Compliance for Safety Glasses

25. Containing little or no iron






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

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






29. Possible to burn






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






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






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






34. Direct Current






35. 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






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






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






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






39. National Electrical Manufaturers Association






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






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






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






43. The property of being porous;being able to absorb fluids






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






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






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






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






48. 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.






49. An affix that added in front of the word
