welding of different steel quality
welding of different steel quality
(OP)
Hi,
Is it okey to use P460NH (endcaps) with P460NL (shell) and weld them together?
They are pretty much the same, but NH is for elevated temperatures, and NL is for low temperatures.
Also what MMA electrodes is recommended for this?
Got recommended on the OK 48.15, but not entirely sure on this.
Thank you very much.

I don`t have a welding procedure for these materials? Where can I find one?
Thanks

You need to define the Design/Construction Code. ASME VIII? European Code with Pressure Directive? Thickness? Minimum Design Metal Temperature?
