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






2. National Electrical Manufaturers Association






3. A movement forward






4. 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.






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






6. 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.






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






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






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






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






11. 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.






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






13. An aperture or hole opening into a bodily cavity






14. Department of Transportation






15. An affix that is added at the end of the word






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






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






18. Containing little or no iron






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






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






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






22. 70% of the heat is concentrated in the workpiece; 30% of the heat is concentrated in the tungsten electrode; Deep penetration; Narrow weld area; welding other materials than aluminum or magnesium






23. Of or relating to or containing iron






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






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






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






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






28. 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.






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






30. 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.






31. Lack of connection of continuity






32. Of or relating to very low temperatures






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






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






35. An affix that added in front of the word






36. Materials or liquids that catch fire easily






37. In constant change
