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






2. 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.






3. Direct Current






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






5. Fastening firmly together






6. 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.

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






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






23. Materials or liquids that catch fire easily






24. 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






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






26. 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.
