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






2. 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






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






4. In constant change






5. These are areas where your hands can become trapped or mashed between two objects






6. 'kilo- pound[- force] per square inch') is 1000 psi






7. Containing little or no iron






8. National Electrical Manufaturers Association






9. 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






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






11. A homogeneous solid that can exist over a range of component chemicals






12. 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.






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