EXAM COMPLETE 200 QUESTIONS AND

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
