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






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






3. 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.






4. American Welding Society






5. 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.






6. Fastening firmly together






7. A movement forward






8. 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






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






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






11. 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






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

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






15. 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.






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






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






18. 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.






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

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






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