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






2. The union of diverse things into one body or form or group






3. 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






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






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






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






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






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






9. An aperture or hole opening into a bodily cavity






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






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






12. Put into a certain place or abstract location






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

15. Visible particles of matter suspended in the air - such as mist or smoke






16. An affix that added in front of the word






17. Materials or liquids that catch fire easily






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






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






20. 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.






21. The distance from which the electrode is from the base metal while you're welding.






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






23. 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. American Welding Society






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






27. Direct Current






28. 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.
