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






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






3. 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.






4. 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.

16. An affix that is added at the end of the word






17. Possible to burn






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






19. Materials or liquids that catch fire easily






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






21. Procedure To prevent the accidental release of energy to equipment being cleaned -






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






23. To treat - combine - or impregnate with carbon - as when casehardening steel.






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






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