Had a front leaf spring hanger, cast iron, on a international semi tractor, cracked in a major crash. I welded it back together with that rod, never had a issue with it.
I know, it is kind of sad, because when you tell about it people will not believe it. I worked with the boats in the 1980ties, so it was already around then. And people are like, it can not be this good, it must be a catch, we better do it the old way, and ended up with a far more expensive repair because of disassembling, machining and all kind of things they had to do. The repairs were high quality, with all that job done, no doubt about that, so it was like, doing it this simple, it can't be a good job.
