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






2. A movement forward






3. Of or relating to or containing iron






4. Possible to burn






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






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






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






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. Materials or liquids that catch fire easily






10. An affix that added in front of the word






11. A metal added in the making of a joint through welding - brazing - or soldering.






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






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






14. 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.






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






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






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






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






19. Fastening firmly together

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






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






23. A cloud- like area where welding fume collects






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






25. 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.






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






27. National Electrical Manufaturers Association






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






29. In constant change






30. 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.






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






32. 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






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






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






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






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






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






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






39. American Welding Society

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






42. 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.






43. 'kilo- pound[- force] per square inch') is 1000 psi
