Is it feasible to weld a sealing ring on the titanium composite tube sheet?
Thread Content
Today I saw the drawings; it’s a titanium composite tube sheet, with a titanium ring attached around the composite layer to serve as a seal. Is such a structure common? Will welding affect the quality of the composite layer?
It’s rare, but considering cost savings, it’s not bad to save titanium material as well
It must be to consider saving materials. I’ve really never seen cladding being welded onto composite plates… It’s quite common, however, to weld accessories or something onto composite plates
Performing additional layer welding after the titanium-steel composite plate has been manufactured is not a good approach, as it can lead to poor adhesion. If the customer insists on using this manufacturing process, they need to sign a document confirming this decision. If the titanium coating is relatively thick, welding might help a bit, but it cannot be guaranteed that no new misalignments will occur. At that time, a composite board with a thicker laminate should have been chosen, and the sealing surface should have been machined.
It is possible to weld a titanium ring. It is possible to weld on the cladding.
It is possible to weld a titanium ring. It is possible to weld on the cladding. Agree with the comment above. There are no difficulties, right?
It’s no problem to control the welding process properly.
This is feasible; welding a composite titanium layer to a titanium ring is not difficult.
It’s really amazing. Currently, our TA composite tube sheets have a composite layer only 3 mm thick, and we also want to use this structure; I think the risks are too high. If delamination occurs due to welding, and by then all the heat exchange tubes have already been manufactured, that would be a serious problem. So, I still think that if there is a step partition on the tube sheet composite layer, it is to save material ； Or, if the composite layer is relatively thick and the flatness of the tube sheet is poor, this structure can be considered; it is not recommended to use this structure in other cases.
