Stitch
A
Spot
B
Plug
C
A wire-feed welding process that does not use traditional shielding gas.
Correct Answer Flux-cored arc welding
Uses a shielding gas dispensed from the torch to protect the weld area and filler rod from atmospheric contamination.
Correct Answer TIG welding
Overhead welds are easy to make because molten metal cannot drip out of the weld and clog the wire feed or gas flow. T/F
False
Pushing is done with the gun held so that the tip of the wire points away from the gun's travel direction. T/F
False
The most common hole size for collision repair work is 5/32² (4 mm). T/F
False
______________________________ are used to duplicate factory spot welds on structural parts.
Plug welds
Uses electrical current to produce enough heat to melt panels together.
Resistance welding
The voltage/heat setting is balanced with the wire speed/amps setting to achieve a stable arc. T/F
True
Uses a combination of squeeze-type resistance spot welding and adhesive to join panels together.
Weld bonding
The use of a flux, a bronze filler rod, and an oxyacetylene torch set to a slightly carburizing flame is known as ______________________________.
brazing
Two panels that are aligned edge to edge is called a(n) ______________________________.
butt joint
The length of time, expressed as a percentage, that a welding machine can operate in a 10-minute period at a particular heat setting is known as the ______________________________.
duty cycle
The length of the wire protruding from the welding gun's contact tube is known as ______________________________.
electrode extension OR stick out
The depth of melting is referred to as ______________________________.
penetration
Contamination on the weld is known as ______________________________.
slag
A short bead that is not more than 3/4?3? (20 mm) long is called a(n) ______________________________.
stitch weld
A combination of squeeze-type resistance spot welding and adhesive to join panels together is known as ______________________________.
