Re: [MW:7265] problem SS 316 flange to pipe welding

Hi,
Why did you done by pressfit for welding of flange to nozzle/pipe? it is not recommended as one of our group member noted before,It should have clearance for expansion during welding also have proper supports shall be provided to avoid such deformations.Also you have to control the heat input during welding.
 
Thanks & Regards,
