General FCAW
The two basic process variations of FCAW.
What is FCAW-S (inner-shield/self-shield) and FCAW-G (dual-sheild)?
The correct type of drive roll to use for FCAW.
What is knurled?
The correct polarity to use for FCAW-G electrodes.
What is DCEP/Reverse?
The FCAW Chapter in the book.
What is Chapter 5?
The correct type of travel angle to use while FCAW welding in the 1F/1G and 2F/2G positions.
What is a drag angle?
Three materials that cannot be welded successfully using FCAW.
What is copper, aluminum, titanium, magnesium, etc. ?
The type of power source most generally used for FCAW welding.
What is Constant Voltage?
The information determined by the "M" in the following electrode classification: E71T-1M.
What is 75-80% argon mix for shielding?
The name of the textbook.
What is Welding Processes, Part 1?
The wind velocity required to blow away shielding gas while using FCAW-G.
What is 5MPH?
Three distinct disadvantages of FCAW.
What is high equipment cost, high equipment complexity, limited portability, limited material, slag must be removed, filler metal is more expensive, sensitive to wind when gas is used, and more fumes?
What is maximum current?
The information the number "4" designates in the following electrode classification: E308LT1-4.
What is 75-80% argon mix for shielding?
Research conducted on manual welds made with SMAW electrodes confirmed this as the predominant gas given off by electrode coverings during welding.
What is CO2?
The instrument that reduces the pressure of the gas cylinder to a lower working pressure.
What is a regulator?
Four functions of the flux.
What is adjusting chemical composition of weld metal, shielding, scavenging impurities/de-oxidizing, influencing the shape and appearance of the weld bead, producing slag, and stabilizing the arc?
The minimum recommended power source current rating for use with .045" FCAW electrodes.
What is 300 amps?
The two most commonly used FCAW-S electrodes.
What is EXXT-8 and EXXT-11?
The year that FCAW was introduced at the AWS Exposition in Buffalo, New York.
What is 1954?
The measurement of how much time a welder spends welding, expressed as a percentage.
What is operator efficiency?
The definition of FCAW.
What is an arc welding process that uses an arc between a continuous filler metal electrode and the weld pool. The process is used with shielding from a flux contained within the tubular electrode, with or without additional shielding from an externally supplied gas, and without the application of pressure?
The five basic components required for FCAW, AND the one basic component of FCAW equipment that may be omitted in some cases.
What is power source, cable assembly, wire feeder, welding gun, and shielding gas (which can be eliminated for FCAW-S)?
The three pieces of information that are determined by the usability number in a FCAW electrode classification
What is required current, number of weld passes, and shielding requirements?
The reason for increasing the amount of Boron inside the flux.
What is grain refinement
The general percentage of heat produced by the arc that is focused on the positive side of a DC welding arc.
What is 70%?
