Welding issues with the demister screen in the separator

Thread Content

The separator is made of Q245R material. A demisting screen is now being added for modification; the original equipment has already undergone heat treatment after welding. Is it possible to weld support rings onto the casing? Can local heat treatment be carried out after welding?

Local heat treatment should work, right?

This question is too general; it’s necessary to analyze specific cases to determine whether heat treatment is required. If local heat treatment is not controlled properly, it can instead generate new stresses.

It is recommended to upload a schematic diagram of the main structure along with its dimensions, so that everyone can analyze it...

It can be done locally, or it can be left undone
