First, here's some tips given to me by a Caterpillar tech. You have to cut a larger section out, make sure and clean everything (these machines are always caked in grease in my experience) and cut bevels into each edge. After you weld in the new plate (no beads wider than 2x the width of your rod and only 7018 or 8018) clean it flat and put what we call a fish plate on top. Cut a square a few inches larger than your repair, and 45* the edges off about 2 inches in on each corner. Weld up the long sides, and don't weld the 45* edges. When you start and finish one of the long edges, make a little curl....don't start/end the actual weld on the part. Start about an inch away from the plate with the little curl, then tie into the fish plate. After learning this, I've never had a boom come back for the same repair.

This seems to be a very professional advice. You actually mentioned the type of welding rod, the scub or fish plate and it makes sense to me that there will be 45 degrees corners on the fish plates to avoid stress concentrations that will be prone to new cracks formation. Great job. It's painful to see an uneducated mechanic produce a nice looking "repair" that will crack again in the near future

The weld looks nice, but it will just crack again after a while. The area immediately around the weld has been severely heat affected making it prone to developing further fractures. If the job is to be done correctly, a stretcher plate should be placed over the repair and welded in carefully. The stretcher plate should also not terminate in a right angle across the boom, instead it should be diamond or V shaped as to avoid creating stress points that might also create possible fractures.

Stop drill the end of the crack with a drill bit. 3/32 or appropriate size this will stress relieve the crack. Then do your welding. Something I learned in aircraft school. Where to start weld I don't know.

@@michaelwesely3097 That's the problem, on something like this there's really no easy way to know how far the crack has propagated if you don't have access to x-ray, or at the very least a dye penetrant test kit. It could well extend most of the way across the boom, which is also another reason to plate over the top of the original material.

I don't see the point of cutting a wide notch just to scab a little chunk inside. You need to think of the whole boom as a dynamic elastic noodle. Now it's got a stiff spot in the middle of an elastic beam. It's going to crack again. You need to add fishplate reinforcement with long feathered slopes to allow elastic bending to occur over a metre of length.

I worked at a sawmill that used 6 excavators with grapples to sort logs in the yard. There was one operator that was constantly breaking machines. Very rough on them. Summer months were already 18 hour days trying to keep up with rolling stock maintenance, then have that one guy causing all kinds of extra work. The worst was the house bearing cracks that ran almost the entire circumference underneath in the well. It had probably over 100 pounds of old grease that pushes out that had to be scooped out into buckets, then steam pressure washed which was absolutely miserable. That hot steam mixed with nasty grease swirled around and plastered your neck. Only after it was cleaned could you see how bad it was. The excavator was very near breaking off and falling off. That replacement bearing 25 years ago was over $50,000 too.

Pretty weld, but it won't last. The metal around the cracks is stressed from the previous weld. Additionally, metal fatigue is an issue. To fix correctly, a six inch section on both sides of the break needs to be cut onto, and a filler plate that's beveled on all sides needs to be welded in place.

As a retired welder, machinist and fabricator, there are 1000 ways to repair the boom. Your way was 1 of them, but it's 850 choices down from being the best choice. Aside from the fact you weren't using enough heat, you should have been using a heavier rod just for starters. And guess what, the boom is going to crack again, but at least twice the size. You don't understand metal fatigue or welding. Quit making videos and go to school or serve an apprenticeship.
