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. Fastening firmly together

8. Lack of connection of continuity






9. Put into a certain place or abstract location






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






11. 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.






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

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






15. Materials or liquids that catch fire easily






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






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






18. Containing little or no iron






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






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






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






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






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






24. A vehicle used to haul goods ; especially : a strong cart or wagon without sides






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






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






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






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






29. Compliance for Safety Glasses






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






31. 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.

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






38. 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.






39. 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
