Zanshin, the pictures mean nothing to my inexperienced eyes but I'd BET that to someone in the business, that is a textbook illustration of some particular failure mode.
Take the weekend off, deal with higher priorities, and maybe Monday see if there are some online resources that look like they might be willing to just eyeball the picture and point you in the right direction.
If there's any type of reference library near you, they may have a reference book on metal fatigue and failures with pics to compare. Or perhaps there's something likle that on the web? Or there's any type of naval yard or elevator shaft repair outfit, where there are welders who have seen this before. Elevator shaft rollers and printing press rollers are both examples of high strength stainless rollers that are welded and refinished in normal use, folks in those trades often know specialty welders.
Heck, maybe someone at the NHTSA or a similar accident investigation agency would be willing to simply respond to an email saying "Please Sir, can you point me in the right direction?" And if nothing else, maybe you can turn up an email contact to a metallurgy department at some university. Or--there are forums for welders and machinists! Someone at one of those is bound to see meaning in that photo.
It most certainly does not look like the typical "this is a metal bar, it got bent and broke" that I've seen.
