What are some metals that gmaw can be used to join? - - -
correct answer ✅carbon steels, high strength low-alloy steels,
stainless steels, aluminum alloys, magnesium alloys, copper alloys
and nickel alloys
What was gmaw originally developed for - - -
correct answer ✅for production welding
what type of power source does gmaw use - - -
correct answer ✅DC power source
, GMAW-P, FCAW, Saw Processes And
Applications Exam Questions And Answers
What polarity is most commonly used - - -
correct answer ✅DCEP
what is the power source used in the welding machine - - -
correct answer ✅constant voltage/constant potential
what type of wire-feed unit is used with a CV - - -
correct answer ✅constant speed feeder (amperage)
what type of wire-feed unit does a constant current use - - -
correct answer ✅voltage controlled feeder
what advantage does a CV power source with a constant speed
wire-feed unit have over a CC power source and a CV in regards to
the arc length - - -
correct answer ✅CV power source and CS wire-feed unit coupled
provide automatic self-regulation of the arc length, whereas with
the alternative combination changes in the arc length create
changes in the voltage. This increases or decreases the speed of the
wire.
