Welcome to another round of Saturday Morning Home Repair Blogging, where experts and amateurs gather to share advice, war stories, and encouragement. Every so often, there's a little mockery, but only of homeowners long past as we fix up their stupid messes
There wasn’t a post in the Que, This isn’t about a home ! There would have been an open thread to chat in so !
I work for a company ( Pro Fabrication ) that builds Exhaust Systems ( headers ) for Internal Combustion Engines. 18 or so months ago a set of boat headers came in. These headers worked with Turbos ! A boat is required by LAW to have a water cooling system to keep from burning the boat to the water !
Pro Fab is into 3 D technology ! So they contacted the company which I think is in France.
A Romer Arm was used to measure the header.
So the first set showed up last week. Some machine work was still needed to be done. Bungs had to be drilled & tapped. Flanges also had to be welded on.
So in this picture you can see the inner & outer wall of the header. Water will be in the middle.
Just below that clamp you can see the weld that connects the flange to the header.
Another flange will be welded to that Rectangular opening & will connect to a turbo.
I don’t know a lot about the 3 D process. But this was a very difficult project that the 3 D company used every bit of technology they had to complete it. the wall thickness is .065. The materal is Inconel 625. They call the process stacking from what I understand. During the stacking process because the piece was so big they had a hard time with keeping the metal from melting like an ice cream cone.
This piece at this time is a one of a kind ! There is a right & left. Not many eyes have seen this. Less than one hundred ! So you are seeing history LOL !
Happy Saturday to You !
