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. 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.






4. Of or relating to very low temperatures






5. American Welding Society






6. An affix that added in front of the word






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






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






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






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






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






12. National Electrical Manufaturers Association






13. A cloud- like area where welding fume collects






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






15. 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.






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






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






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