CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) |ALREADY GRADED A+
How does the TIG process work? - - ANS✔️--Control amps, 2 leads (one ground, one torch),
torch holds tungsten electrode that passes current
What is the main difference between GTAW and SMAW - - ANS✔️--In GTAW the tungsten
electrode does not melt into the base metal
SMAW - - ANS✔️--Stick welding; Shield metal arc welding
GMAW - - ANS✔️--MIG; gas metal arc welding
FCAW - - ANS✔️--flux cored arc welding
GTAW - - ANS✔️--TIG; gas tungsten arc welding
OFW - - ANS✔️--oxy fuel welding
,the three types of currents that can be used while welding - - ANS✔️--Direct Current Electrode
Negative; Direct Current Electrode Positive; Alternating Current
Straight Polarity - - ANS✔️--DCEN; direct current electrode negative
Reverse Polarity - - ANS✔️--Direct current electrode positive; DCEP
Current type depends on ___ for MIG and TIG and ___ for SMAW - - ANS✔️--MIG and TIG
depend on type of metal being welded; SMAW depends on what type of electrode you are using
Most common SMAW electrode types used - - ANS✔️--E6010 and E7018
What current type do E6010 and E7019 for SMAW use - - ANS✔️--DCEP
What type of current is used for GMAW (MIG) of steel - - ANS✔️--DCEP
What type current is used for GTAW when welding stainless steel and carbon steel - - ANS✔️--
DCEN
What does each number stand for in SMAW electrodes:
E60XX =
,EXX1X=
EXXX0= - - ANS✔️--E60XX= tensile strength (ksi)
EXX1X= position; 1 is all positions
EXXX0= chemical comp of the flux coating of filler metal
How does SMAW (stick) work? - - ANS✔️--Set amps, attach one lead to work piece, other lead
has handle, and complete the circuit. Arc melts the base metal and filler metal simultaneously
In SMAW what temperature can the arc reach? - - ANS✔️--10,000 F
In SMAW what creates the shield that protects the weld puddle from bonding with elements in
the atmosphere? - - ANS✔️--Flux coating around the electrode
What elements do we need to keep away from the molten metal? - - ANS✔️--Oxygen (will create
porosity or voids) and Hydrogen (will make the metal brittle and cause Hydrogen cracking)
How does the slag that is not burned into shield gas operate? - - ANS✔️--It melts into the weld
puddle, rises to the surface, and hardens on top of the weld. It needs to be removed
Which processes have slag? - - ANS✔️--SMAW, FCAW
, How does FCAW differ from GMAW? - - ANS✔️--They are the same process except FCAW
uses a tubular wire filled with flux and requires no external shielding gas source
Describe how GMAW works. - - ANS✔️--Semi-automatic process with two leads (gun and
ground); when gun is squeezed electricity flows and filler wire is fed.
What are the parts of a GMAW gun? - - ANS✔️--Handle, trigger, and nozzle
What type of filler wire is fed in GMAW? - - ANS✔️--Solid wire type
What nobs can you control on GMAW - - ANS✔️--Voltage and Wire Feed speed
What are the 3 main transfer types for MIG (how the metal gets from the filler metal to base
metal) - - ANS✔️--Short-Circuit, Globular, and Spray Transfer
Where does the shield metal gas come from in MIG? - - ANS✔️--From a separate tank that is
sprayed out of the nozzle in the gun
In GMAW, what shield gas is used for carbon steel? - - ANS✔️--75Ar/25Co2
What happens when you add Helium or Hydrogen to the shield gas for MIG of carbon steel? - -
ANS✔️--makes the arc hotter
