Q

What does the complete weld symbol provide for the welder?

63
Q

Note how gravity affects the molten weld pools in different joint positions. In addition to this, __________ also varies with each position.

A

Heat Distribution

64
Q

What is tack welding used for?

A

Stability and holding components together during assembly.

65
Q

Expansion of the base metal during welding often will cause a condition known as ________.

A

Mismatch

66
Q

Overall weld dimensions have a small tolerance; Why?

A

For weld shrinkage

67
