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 homogeneous solid that can exist over a range of component chemicals






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






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






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






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






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






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






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






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






10. 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.






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






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






13. 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
