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. 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






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






3. The basic unit of electric current adopted under the Systeme International d'Unites






4. Materials or liquids that catch fire easily

6. Put into a certain place or abstract location






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






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






9. Threshold Limit Value (TLV) of a chemical substance is a level to which it is believed a worker can be exposed day after day for a working lifetime without adverse health effects.






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






11. 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.
