Heat Distribution
64
What is tack welding used for?
Stability and holding components together during assembly.
65
Expansion of the base metal during welding often will cause a condition known as \_\_\_\_\_\_\_\_.
Mismatch
66
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
69
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
71
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
73
Tooling and bars used to remove heat from the weld and resist heat into the base material are sometimes called \_\_\_\_\_\_\_\_.

77
Fillet welds are always measure by the length of the fillet \_\_\_\_\_\_\_\_.
legs. (Unsure of this answer)
78
The condition of a butt joint where neither the top nor the bottom edge of the material is flush is called \_\_\_\_\_\_\_\_\_\_\_\_\_.

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)
