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






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






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






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






6. 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.






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






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






9. 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.






10. Compliance for Safety Glasses






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

20. In constant change






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






22. Fastening firmly together






23. Materials or liquids that catch fire easily






24. 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






25. Direct Current






26. 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






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






28. Of or relating to or caused by a toxin or poison






29. 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.






30. Containing little or no iron






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