Note how gravity affects the molten weld pools in different joint positions. In addition to this, __________ also varies with each position.
Heat Distribution
What is tack welding used for?
Stability and holding components together during assembly.
Expansion of the base metal during welding often will cause a condition known as ________.
Mismatch
Overall weld dimensions have a small tolerance; Why?
For weld shrinkage
Fille welds leg length must be equal to the thickness of the _________ base material.
Thinner
Where the component parts are not in close contact a _____ must then be made.
Bridging Fillet Weld
What is an interference fit?
The outer cylindrical part is headed until it expands enough to slide over the inner part. As the part cools, it shrinks and locks the two pieces togeather.
What are the 3 common corner weld joint designs?
Edge to Edge, Flush, Half overlap
Preheating is generally use to do what and prevent what?
Used to slow down the cooling rate of the weld to prevent cracking.
The Min/Max temperature at which a weld can be made on a multi-pass weld is called _______.
Interpass temperature
Tooling and bars used to remove heat from the weld and resist heat into the base material are sometimes called ________.
Chill Bars
Welds made from both sides of the joint are called______.
double welds
Where high-strength welds are required, a ____ joint weld with 100 percent penetration is used.
Butt
Unless tack welds are made properly, they often ______ during the welding operation.
Crack
Fillet welds are always measure by the length of the fillet ________.
legs. (Unsure of this answer)
The condition of a butt joint where neither the top nor the bottom edge of the material is flush is called _____________.
Mismatch
________ joints always shrink across the weld joints.
Butt
The main problem in making fillet welds is _____ _________ ________ into the root of the joint.
lack of penetration
Edge-type joints without full penetratin of the weld should not be used in _________.
stress or pressure application

What does the weld designer want?
What does the weld designer want?
What does the weld designer want?
What does the weld designer want?
What does the tail of the welding symbol used indicate?
The welding or cutting processes, as wel as teh welding specification, procedures or supplementary information.
A weld symbole without a flag indicates the the weld is to made in ______.
shop
What are 3 components to a weld symbol?
The arrow line, reference line, and tail.
What does the field weld symbol look like?
A flag
What does the numbers mean on either side of the symbols?
left of sign = leg size, weld length (if numbers are more than one like 2-4, it is the intermittent weld length and pitch)
What is the root of a weld?

What are the toes of a weld?
Edges or the points of the hypotenuse.
