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. Materials or liquids that catch fire easily






3. Air conditioning; alternating current






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






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






6. In constant change






7. 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.






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






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

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






15. Of or relating to or containing iron






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






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






18. To treat - combine - or impregnate with carbon - as when casehardening steel.

26. 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.






27. Possible to burn






28. A cloud- like area where welding fume collects






29. Containing little or no iron






30. American Welding Society






31. 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.






32. Fastening firmly together






33. 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

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






36. 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
