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






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






3. American Welding Society






4. A government agency in the Department of Labor to maintain a safe and healthy work environment






5. Cut - notch or groove; quantity of something cut at the same time






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






7. Containing little or no iron






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






9. Put into a certain place or abstract location






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






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






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






13. 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.

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






23. Direct Current






24. Any of the chemically inert gaseous elements of the helium group in the periodic table






25. Shield consisting of an arrangement of metal mesh or plates designed to protect electronic equipment from ambient electromagnetic interference






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






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






28. 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.






29. An affix that added in front of the word






30. A conductor used to make electrical contact with some part of a circuit






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






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

42. The property of being porous;being able to absorb fluids






43. National Electrical Manufaturers Association






44. 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.






45. 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.

50. Discontinuity in a groove weld in which the weld metal doesn't extend through the joint thickness.
