Dear Sirs.

can we weld CS shoe on SS Pipe with SS pad at 425C temp ?

E(alphass-alphacs)*dt comes very high - will CS side be highly stressed and crack can initiate!

Some FEA findings indicate the same. Please advise there is any reason for worry at this temp 425C for such CS-SS weld?

Can better weld procedure reduce such crack possibility?
