We produce a part for an aerospace customer. The part is titanium and requires machining, alkaline cleaning, press fit (titanium) plugs installed, electron beam welding and then subsequent stress relieve.
The material is AMS 4928 (6AL-4V).
The welding is performed in a vacuum. There is...
Home Run!
iainuts, you have described superbly what I have been able to confirm with a secondary experiment.
I took one of the details ant bolted it to a 1" thick steel plate. I applied torque to the bolts and measured the parallelism as follows:
50 in/lbs, .0004"
100 in/lbs, .0010"
150...
Thank you all again!
I agree, the sketch is very vague. I was hoping that it wasn't so vague as to be useless as I cannot post the exact configuration.
This isn't a pressure vessel. In simplest terms it is a two piece pillow block to hold bearings. The placement of the bolts was dictated by...
People,
Thank you all for the input!
Here's a little more information.
The two parts are Titanium, 6AL-4V.
I did try several techniques on the tightening of the bolts. Mostly bringing them up in 50 in/lbs increments uniformly. Once I get to 150 in/lbs, the distortion takes place (out of...
We a reproducung a part for a customer that is two pieces bolted together as an assembly. The mating surface of each part is flat w/in .0003". The surface opposite both of the mating surfaces is parallel w/in .0008".
When the parts are bolted together, we use four bolts torqued to 185 in/lbs...
