GMAW
The weld pool in GMAW is protected by this?
what is a shielding gas
the weight of a full spool of wire that your currently welding with would be this number in lbs
what is 44lbs
this gas will produce the smoothest welding arc on aluminum?
what is argon ( Ar )
in the GMAW welding process, these settings would decrease spatter and improve arc stability
what is slope and inductance
constant voltage wire feeders are used with this type of wire feeders
what is constant speed wire feeders
This is the most common power used with GMAW
what is Constant Voltage
the "2" in the CSA filler wire (E492T-11) would indicate this
what is flat & horizontal welding position only.
shielding gas of 100% Ar is most widely used on these metals
what is non ferrous metals
on a CV power source, if i moved my arc length closer to the work, what would happen to my volts & amps?
volts drop slightly
welding current (amps) increase
this is an example of a primary variable
what is arc voltage & wire feed speed (current)
this is how ozone gas is produced
what is ultraviolet arc burning oxygen in atmosphere
this shielding gas in normally used with FCAW
What is carbon dioxide or carbon dioxide mixed with another gas
the harsh welding arc characteristic of a co2 shielding gas is the result of this effect
whats is cathode jet
this would describe a volt amp curve for CV
what is a flat curve or "flat operating point"
drive motor is variable speed on this machine
what is constant current
in GMAW the gas, carbon dioxide breaks down into..?
carbon monoxide and oxygen
E49 2 T-9-CH is used by what governing body for FCAW wire
what is CSA standard
when O2 is used in an argon shielding gas mixture, the result is this
what is deeper penetration
this would be another name for Constant Voltage
what is constant potential
this type of power source must be used for pulsed current welding
inverter power source
this combination produces the greatest amount of radiation
what is welding with 100% argon on aluminum
this classification of self shielded wire is designed for high deposition , all position welding .
it is used on DCEN and can be used for single or multi pass welding
what is T-8 Classification
this shielding gas mixture is widely used for spray metal transfer on stainless steels
what is 99%Ar - 1% O2
this is the name for the voltage reading while welding is taking place
what is the load voltage
name the four different secondary adjustable variables
1) pushing and pulling technique
2) travel speed
3) electrode extension (stick out)
4) electrode angle
