hello,

I want to know that during the welding of the two 12mm plate I am getting the root gap of appr 35 mm. How can i weld these two plates? can the buttering technique help it? Do i need to do any PWHT for this? and whether the stress reliving is necessary for this welding?

Hello Munish kumar,
Welcome to the AWS Forum.

Before your question can be answered, you need to provide A LOT more detail.

To start with:
Weld code?
Plate material?
Weld process?

Then a lot more questions to follow.

PS - Do not post your question in multiple sections in this forum.

Munish,

That's a wide root opening. What code are you dealing with? It looks like you may need the engineer's opinion more than ours to get an okay on that.

If not an engineer situation, buttering to close the gap with no tie in until after the opening has been reduced and the materials brought back to a low temp then start on the weld as normal.

He Is In Control, Have a Great Day, Brent
