Hello
I have a problem that I can`t find any information about in books or internet so I will try this forum.
Let`s say that you have a bar Ø100mm in 316 material.
This bar is coated with 2,5 mm of weld that has a lower thermal expansion coefficient. How can I calculate the total expansion?.
The weld will work as a bearing and the bar will be fitted into a hole that is the other bearing surface, this part is also made of 316 material and the inner Ø of the hole will also be coated with a weld material that has similar thermal expansion coeff. as weld No 1.
How can I calculate necessary gap between those two surfaces?
