Forensic metal failure analysis. This is a basic study as to how things break. This exact failure can be seen in u-joints, leaf springs drive lines. I got my introduction into failure analysis when I worked for Cummins in the late1970's, they used to publish training manuals. So we would get a new booklet on various truck related issues, work would quit early, pizza would be served. They did things like drive line vibration, different topics. The one i remember was metal failure types and how to read them. This one as you say probably started in the unnecessary hole. I think the term that was used was "shelling" [as in sea shells] the pattern from where the crack originates leads directly to where the crack starts. The most interesting one I had was a harmonic vibration. The are ultra sonic vibrations that melt metal molecule. Those training sessions that companies used to do in the early days was great stuff!

@bobbruin44 Ай бұрын

Wouldn’t the place where the crack originates be the same as where the crack starts?

@jeffreywhitmoyer860 10 күн бұрын

The failure type is often referred to as beach marks. Classic fatigue failure. 30+ years ago I worked with a Cat vendor who was producing a variety of components for Cat. As I recall a lot of their materials were low alloy steels, 8620 and 8630 in particular. They had a lot of unusual testing requirements and in some cases odd heat treatments to achieve the required strength levels. When I watch these videos I have to wonder if any of the components you repair are actually low/medium carbon steel or are alloy. It's something that could affect filler choice and 42:35 the longevity of the welds. The only way to know would be to get your hands on Cats Specs or cultivate a friend with a Porta Spec. Spark testing can also give a good indication of composition. Other than that, your welding and preparation methods are spot on. Don't mean to be a smart ass, just sharing some thoughts.

@billcovert3473 10 күн бұрын

@@jeffreywhitmoyer860 Yes beach marks. They tell a tale of the failures originating from the crack source. I am in trucking, this knowledge is important as whether the failure is operator abuse, or perhaps a shock load at a earlier date. I don't get into the equipment welding repairs, but I have learned good tips from Greg and I C Weld as I run a service truck doing road work [45 years]but every now and then do metal work. Smart, yes. Ass, no.

It des not take a welding engineer to see why that member broke...That huge hole in the middle reduced 1/2 the strength of it IMHO. Super great repair job Greg.

@nunyanina583 28 күн бұрын

Lift point, foolish but at the board meeting years ago was a young engineer who blew a lot of smoke up , well I think you get the picture. I watch CEE Channel out of Australia and I don't see many poor equipment design. Most is due to poor maintenance, pushing limits when a crack forms because of time constraints, not have the available down time. That's kinda what I think happened here. I think they saw the crack forming in my opinion. This guy could have welded the crack strait through and still put the plate on. Never seeing him work before, there is no doubt to his welds. But not replacing the Bushing and line bore to oem specs, it will end up back in the shop for just that real soon. I think anyway.

The hole location for the angle sensor is wetoddid. The mistake was easy to make but the designers letting such silliness leave the factory was goofy vs. welding a shield to protect the electrics rather than burying it which no doubt someone was proud of because it looked cooler. BTW the squirt bottle trick is classic and works a treat with water-based machining coolants too.

@williamthomas9463 Ай бұрын

Bet that was exciting at the moment that broke! I appreciated the fact that you preheated it. It amazes me at how many customers have told me over the years that I was the first weldor they’ve ever seen do any preheating. Naturally, they assume, since they have never seen it or understand why, that I don’t know what I’m doing and it’s just a waste of time 🤦🏻‍♂️!

Nice repair and that 3M disk is a grand tool... Those tapped holes for the sensor certainly appear to have contributed to the failure. Maybe the design would be strengthened if they used surface welded studs for the sensor plate mounting, rather than drilling so many holes into what must be a highly stressed part of the loader arm?

Then let it cool before turning the bolt out. May take a couple tries but It works almost every time. I spent way to much money on drillbits, extractors, and taps in the past.

When something breaks and you really didn't abuse it, I think it's a good idea to reinforce it. It really shouldn't lift anything heavier than it is rated for. Doesn't look like a good way to do that sensor. I thought it looked like a factory lifting point was the reason for the hole.
