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.

23. A movement forward






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

30. National Electrical Manufaturers Association






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






32. 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.






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






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






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






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






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






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






39. 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.
