needs better articulation.. does the color being more or less red show that steel has sulfur impurities? what processes would you use to get rid of sulfur?

"Hot Shortness" of Aluminum

I am currently in Welding School, and this is a cause of most cracking in aluminum welds. Does anyone here know more about this, also i assume there could/should be a page on the phenomenon of "Hot Shorting" that is not tied to a specific metal, or no?
Also i am NOT an expert in this area, so wouldn't 100% to dive into this / write the page, but if given advice i could maybe lay out the basics?
I am also looking into other wiki's content on this
- This is something i am curious about the extent as to how far this has been done across wikipedia? Re-convene all the wikis in existence to an extent, "compare notes" and all that. Here i go getting off topic lol
Relevant Link Spam i forgot to add in the original post:

- https://www.sciencedirect.com/topics/engineering/hot-shortness — Preceding unsigned comment added by Eric Lotze (talk • contribs) 04:59, 29 November 2021 (UTC)[reply]

Anyhow just wanted to ask if any of you know more about the phenomenon and/or where i should document information on it in Wikipedia?
