Re: [MW:35148] Buttering

PL correct if I am wrong 

Er309 L is wrongly written .

It is CS TO LAS joint 

Then 309L is not a compatible consumable .

You can chose either E7018 or E 8018 B2 ( LAS if Gr 11 type)

Here you can butter E7018 - 1  on GR 11 edge 

Do PWHT 

Prepare bevel 

Then do DPT/MPT

Then weld the CS with E7018 /E7018-1

Hi, 

I hope you are all very well.

I wanted to know the reason behind why we use inconnect and E309L electrodes for buttering? what is the reason behind using those? Suppose a dissimilar weld between low alloy and carbon steel. We do buttering of inconnel on Low alloy metal.
