Topics of this game:
  • Which type of metal transfer is limited to use on thin stainless steel?
  • ___________ is not suitable for all position welding on stainless steel.
  • Spray transfer welding requires _____________ shielding.
  • Electrode orientation affects bead shape and penetration to a greater extent than arc voltage or ________________.
  • Spray transfer requires the use of direct current, a positive electrode (DCEP), and a current level above a critical value called the ____________ current.
  • Because the spray transfer drops are smaller than the arc length, _________________ don't occur and spatter is negligible, if not totally eliminated.
  • When all other variables are held constant, increasing welding current (wire feed speed) results in all except ______________.
  • The current and polarity selection for GMAW is ______________.
  • With all variables held constant, arc voltage is directly related to ______________.
  • A voltage increase tends to _____________ the weld bead and increase the width of the fusion zone.
  • Excessively high voltage may cause all except _____________.
  • At _____________ travel speeds, the welding arc impinges on the molten weld pool, which reduces the effective penetration.
  • For welding aluminum, which mode of metal transfer is preferred, even in all positions?
  • For some materials, such as aluminum, a ___________ technique is preferred.
  • A prolonged temperature of 800 to 1600 degrees fahrenheit when welding stainless steel can cause ________________.
