First you have to understand that sweeping is NOT based on any scales.

Sweeping is arpeggiating. That's all it is. When you sweep pick all you're doing is arpeggiating a chord.

So, having said that, you need to know how to build chords and you need to know the chord progression that you're going to be sweeping over, since, odds are, that you're going to be sweeping using the chord in the backing.

Here's something that I figured out all by myself by looking at solos using sweeping, namely those on the Dethalbum and Dethalbum II, both by Dethklok.

There are two basic sweeps used: major and minor. Here's the tabs:

You can easily make them from a C chord shape.
Major:
E|-15p12----------------------------12h15p12-|
B|----------13--------------------13---------------|
G|--------------12------------12-------------------|
D|------------------14----14-----------------------|
A|----------------------15--------------------------|

Intervals: IV III I IV III I III IV I III IV III
Basically, it's a major appregio.

Minor:
E|-15p11-----------------------11h15p11-|
B|---------13----------------13--------------|
G|------------12---------12------------------|
D|---------------13---13---------------------|
A|-------------------15-----------------------|

Intervals: IV iii I IV iii I iii IV I iii IV I iii IV iii
It's a minor appregio.

Bear in mind that you can move them anywhere on the fretboard, and you don't need the hammer-ons and pull-offs on the high e string. The low E string isn't used for these.

They can get a bit more complex with some slides.

Major:
E|-15p12-------------------------------------------12h15p12-|
B|---------13------------------------------------13--------------|
G|------------12\9------------------------9/12------------------|
D|-------------------10----------------10------------------------|
A|-----------------------10\7---7/10----------------------------|
E|------------------------------7----------------------------------|
IV III I IV III I IV III I III IV I III IV I III IV III

Minor:
E|-15p11---------------------------------------11p15p11-|
B|---------13---------------------------------13-------------|
G|------------12\8---------------------12/8-----------------|
D|------------------10--------------10-----------------------|
A|----------------------10\6--6/10--------------------------|
E|----------------------------6--------------------------------|
IV iii I IV iiii I IV iiii I iii IV I iii IV I iii IV iii

Except for the hammer-on and pull-off, You should be able to play those using only your index and middle fingers. I do, anyway.

You can also make Minor and Major sweeps from the Major and Minor A chords, moving them up and down the frets. The hammer-on is a fourth above the top note. Here's the intervals:

Major - I IV III I IV I IV I III IV I IV

Minor - I IV I iii IV I IV I iii I IV I IV

So practice those until your fingers know them well. The top four notes on the top three strings are often used for some more speed. Try adding a tap to the top of the sweeps, see what you can do. Just remember which one is Major and Minor, and you should bo good.
