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






2. Put into a certain place or abstract location






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






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






5. Containing little or no iron






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






7. The American Conference of Governmental Industrial Hygienists (ACGIH); develops TLVs and BEIs as guidelines to assist in the control of health hazards






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






9. Lack of connection of continuity






10. 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






11. An affix that added in front of the word






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






13. 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.






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






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






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






17. Direct Current






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






19. 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






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






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






22. Air conditioning; alternating current






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






24. 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.






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






26. A set of rules or principles or laws (especially written ones)






27. In constant change






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






29. PSI (pounds per square inch ) a unit of pressure equal to 6.895 x 10 Pa or 51.71 torr






30. Materials or liquids that catch fire easily






31. 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.






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






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






34. Of or relating to or containing iron






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

37. Possible to burn






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






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