Types of Welding
This joins together two pieces of metal, using an electrical supply to fuse the base metal with a consumable electrode filler.
MIG Welding
Which weld procedure is safe to perform in wet conditions?
None, it is not safe to weld while standing in water. Water conducts electricity, increasing the risk of electric shock, which can be fatal.
To join by fusion
Weld
The piece of equipment that holds the electrode.
Electrode holder or Stinger
This gas produces flame temperatures in the range of 5800 degrees to 6300 degrees when mixed with oxygen.
Acetylene
A welding process that uses a metal rod with a flux coating to create a weld between the rod and a workpiece.
Stick (Arc) Welding
This is the minimum recommended filter shade on a welding helmet to protect your eyes.
Shade 10
Continuous line of filler metal
Bead
The electrode that is used in the GTAW process.
Tungsten
What type of weld would you do to form a T shape between two pieces of flat bar?
Fillet
A welding process where two metals are fused using a beam of high-velocity electrons or a laser.
Electron Beam and Laser Welding
What is the type of respiratory protection is the minimum required when welding?
P2 Respirator
Making a small weld to hold metal parts temporarily
Tacking
A welding machine used for welding shielding metal arc welding.
Constant current welding machine
When performing a fillet weld between two pieces of 5mm thick mild steel, what is the recommended size (leg length) of the weld? (when not given a size)
5mm
A welding process that uses a tubular electrode filled with flux to join metals and other materials
Flux-Cored Arc Welding
What protective clothing is needed in arc welding?
Protective clothing needed for welding includes general fire resistant clothing, safety glasses, shoes, gloves, helmet and leathers.
Coating on the welding rod
Flux
A welding machine that is used to weld aluminum
A high frequency welding machine
How would you prepare heavily rusted mild steel for welding?
Grind back to bare metal
This is an arc welding process that produces the weld with a non-consumable tungsten electrode
TIG Welding
When is a stick electrode “electrically hot”?
A stick electrode is always “electrically hot” when the welder is on.
Metal welding rod coated with flux and used in an electric welder
Electrode
Welding machine that operates with 100% ____ can run continuously without overheating
Duty Cycle
This position requires the welder to manipulate the welding rod in a side to side motion to control the weld puddle
Vertical up position
