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 movement forward






2. 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.






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






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






5. An aperture or hole opening into a bodily cavity






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






7. 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.






8. Compliance for Safety Glasses






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






10. 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.






11. Cut - notch or groove; quantity of something cut at the same time






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






13. Materials or liquids that catch fire easily






14. In constant change






15. 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.






16. 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
