[MW:23089] Re: Whether we can weld SA 335 P11 and SA 335 P91

here given electrode rod is used for

P11-P22  E8018 B2 and

P91-P22 E9018 B3

so my transition piece material should be SA335 P22

if yes  Can we use min 1d length for our transition piece SA335 P22

if No what would be the transition piece material

we are not having any option to have direct weld in between these P11 and P91 due to Cr% (melting point will be vary) in chemical composition

In my condensing system my header line is having 2 materials

The line above sprayer which was connecting with condenser is SA 335 P11

And after sprayer till loop is SA 335 P91

 

Now my problem is whether we can weld or connect this SA 335 P11 and SA 335 P91 ?
