Use aluminum "pins" ?
Then after the edges are welded, finish either with autogenous welding the ends of the pin(s) and holes or use pins slightly shorter than the assembly thickness to permit real "plug welds."
Even with pins installed I think the halves of the welded assembly will likely...
I wonder what a cutting edge world class 3500 hp electric tug would look like.
The solar panels might have a vaguely familiar look.

"GE spec's installation torque has no mention of preload/axial load at all, the protrusion is what defines the "installed" state for the max installation torque."
I suggest proceeding carefully.
I'd interpret protrusion as the number of screw/bolt threads visible beyond the nut.
"Producing a...
By inspection I always wondered what arched tower braces, attached with offset thin plate brackets could really offer.
In comparison, the 1960s Shelby Mustang braces to the firewall looked to me to provide a 10X stiffer load path...
How long was the shaft in service?
I'm still unclear whether the fracture surface propagated from a groove machined in the shaft.
Any micromotion of the shaft within the bearing at the edge near the shaft shoulder would cause fretting. The endurance strength of a fretted surface is mighty low...
It has only been a couple of days, but OP ain't been back since Sept 23, the day of his original post.
I do not understand the axis of rotation ( among other things). And as a result, also not the tendency for "the size of the groove" to "change during rotation."
//Maybe// if the groove was...
"Grade 8.8 bolts are heat treated by quenching and tempering in accordance with the DIN 933 grade 8.8 standard.
This process involves:
- Heating the steel to around 870°C, where it transforms into a γ-austenite crystalline structure
- Rapidly cooling the steel, which transforms the austenite...
Like MFGENGGEAR said-
Contact stress
Contact wear
Beam strength (deflection)

I think focussing on deflection with the goal of limiting it to "only be a few % of the height of the teeth" might be overlooking potentially serious problems elsewhere, especially if the rpm and tooth...
My 2013 Mazda CX-5 FWD with manual transmission loves to buck at small throttle openings and low rpm in first gear.
It also spins its tires easily at pretty modest 1st gear starting acceleration.
That has been a little surprising with the front wheel biased weight distribution.
I'm...

Is the installed "grip length" about 20 mm?
By grip length I mean from under-head to the first/upper-most thread of the tapped hole.
Attached info Meehanite E From 1962 4th edition of Woldman's Engineering Alloys.
Like others said Grade E was superseded by grade GE.
But no GE info is listed.
Modern info for GE-30 is available online...
"400 BHN as per the OEM standards."
Are you an aftermarket parts supplier?
I'd find some detailed close up pictures of failed tooth adapters interesting.
And with some new parts to help better understand any deformation that may have happened in addition to breakage.
Any history available...
"The Ansys results are showing the expansion of gear tooth is more than the pinion tooth."
How long is a rope?
And the radial expansion due to "centrifugal force" is .............
2µm, 10 mm, ????
"Please clarify."
You go first.
Describing technical results with adjectives like MORE, LESS...
"Please clarify."
ditto
"I think, as the the gear is larger in size, the growth or expansion of the gear tooth is more than the pinion tooth."
But the rpm of the pinion is faster in direct proportion to the diameters.
The relative thickness of the gear rim ( bore to dedendum/root circle) may...
Every now and then o-rings and seals swollen by brief contact with the wrong fluid have mostly recovered dimensionally when cleaned with mild detergent then isopropyl alcohol, dried and gently warmed over night.
the next time that happens to me I might try using an Air conditioning vacuum pump...
Does the new valve stem have plating of some kind ?
Can the valve guides be identified as iron or some flavor of bronze ?
I'm sorry if I missed if both intake and exhaust valves are not fairing well.
Modern Chevrolet LS engines have remarkably low wear rates.
I don't know if their...
What is the loading of the bolts in your assembly? What service life is required?
What is the welding these bolts will be subjected to ?
Tack welding heads to a substantial main component?
Welding the bolt head to a component to create a stud?
Something else altogether ?
Depending on your...
