The GMAW chapter in the textbook.
What is Chapter 4?
The distance from the contact tip to the base material.
What is contact tube to work distance (CTWD)?
The type of power source most commonly used for GMAW welding.
What is constant voltage?
The most commonly used GMAW electrode in this class.
What is ER70S-6?
The transfer mode with no advantages.
What is globular transfer?
The name of the textbook.
What is Welding Processes, Part 1?
Four advantages of GMAW.
What is the ability to weld a wide variety of base metals, increased efficiency/productivity, all-position welding, deeper penetration than SMAW (spray transfer only), minimal post-weld clean up, low-hydrogen process, and user-friendliness?
The transfer mode that CV slope affects the most.
What is GMAW-S?
The two measurements used that control/indicate how tightly the welding wire is wound around the spool.
What is cast and helix?
The transfer mode that requires a programmable power source to use.
What is GMAW-P?
The first year that GMAW became commercially available.
What is 1948?
Both names of the type of volt-amp curve most commonly used with GMAW.
What is constant voltage and constant potential?
The maximum rating that can be achieved by water-cooled GMAW guns?
What is 700 amps?
What is E=Electrode, R=Rod, 70=70,000PSI Ultimate Tensile Strength, S=Solid, 2= Chemical Composition.
The minimum quantity and type of shielding gas required to utilize axial spray?
What is 80% argon?
One of the GMAW process variations listed in the book.
What is Gas Metal Arc Spot Welding, Narrow Groove Gas Metal Arc Welding, Gas Metal Arc Braze Welding, or Tandem Gas Metal Arc Welding?
The definition of GMAW.
What is an arc welding process using an arc between a continuously fed consumable electrode and the weld pool. The process is used with shielding from an externally supplied gas and without the application of pressure?
The five basic components of GMAW.
What is torch, cable assembly, wire feeder, power source, and shielding gas delivery system?
The most commonly used tri-mix used for stainless steel GMAW?
What is 90% He, 7.5% Ar, 2.5% CO2
The two "specialized" GMAW-S type transfer mode programs developed specifically for open-root joints.
What is STT and RMD?
