A garage sale mistake here:
http://igor.chudov.com/tmp/aluminum-wrench.jpg
This is a 24" aluminum pipe wrench.
If you look closely, you will see that this wrench has a crack on the
left side that I did not notice.
This seems to be a good case for trying to do aluminum welding for
some good reason.
So my question is, is welding of this wrench, a bad idea for any
reason? Any idea what kind of aluminum these wrenches are made of?

Hmm, aluminum, or an aluminum-magnesium alloy?

I've wondered that myself, and I don't know. My guess is a moderately strong
but moderately priced alloy that also forges easily; maybe 6061. If it's
2024 (possible) or 7075 (very unlikely), you can't weld it and produce a
strong fix.
Aluminum alloy-testing kits tend to be expensive. But the tests for 2024 are
simple; I forget what they are. What you're looking for is copper in the
alloy. Any of the 2000-series are going to give you welding trouble unless
you're very knowledgable.
The ASM published a book of simple tests that's supposed to be really good,
but I've never seen it. You may find it in a university library: _Rapid Spot
Testing of Metals, Alloys and Coatings_, by Andrew Holmes.

Worst case it's still worth 75 cents a pound at the scrap recyclers. If you
paid a buck or two at a garage sale you can get your money out that way.

It doesn't apply in your case, but my grandfather used to repair iron Ridgid
pipe wrenches. He was retired from Ridgid at their main plant in Elyria, Ohio,
and they outsourced the repair of large pipe and nut wrenches used in the oil
fields.
Many is the time when I was little (1950's) that I watched him grind the
bevels, and braze a wrench. He used a large rosebud tip with the flame set so
soft it waved around as he moved the torch, making a soft hiss that I can still
recall.
He used to tell me they would sometimes get a wrench back for another break,
but the braze repair held and the wrench broke in another spot.
