Welding Safety Quizzes & Trivia

Welding is an extremely noble craft, however the level of heat and subsequent danger that comes with it can be quite daunting. Do you know the proper safety protocols when it comes to welding? Let’s find out.


Questions and Answers
  • 1. 
    You are working with a GTAW welding machine that has a duty cycle of only 10 percent.  You know to:
    • A. 

      Increase amperage to accomplish more welding in a shorter time.

    • B. 

      Pay careful attention to the actual time you spend welding.

    • C. 

      Stop every ten minutes to let the machine cool down.

  • 2. 
    You are working with a GTAW machine that has a 20 percent duty cycle.  You estimate the welding job will take at least 30 minutes.  You know to:
    • A. 

      Operate the machine for 6 minutes, then let it cool for 6 minutes.

    • B. 

      The duty cycle will cover the entire time span so just complete the weld and be done with it.
