Narrow Groove welding technical details.

[qalab]

Hello,

I'm working on Narrow Groove Welding of Carbon Steel for pressure Vessels (SA 516 Gr. 70)
I donot want to go for Backing strip method. Hence prefer the Back gouging method.

Wanted to know from where can i get the Groove design detail and the consumable detail along with the current and voltage , speed settings for the same.

There is information on the internet. I would use the Google tool bar above and type in key words, like "narrow groove welding" or "narrow groove weld detail".

"The Procedure Handbook of Arc Welding" published by Lincoln Electric will get you started. Another option is to post on the AWS forum.

Give us a little more info on process, material thickness, etc. and we may be able to help.

Your welding procedure for your pressure vessel will have to be per ASME Section IX.

thanks for the reply.

Well the thickness of the vessel as mentioned above is 100mm and materail of const. SA 516 Gr. 70.

I don't have the copy mentioned by Carburize' "Developments in Pressure Vessel Technology-3" Edited by R W Nichols - Applied Science Publishers - London

I would be using SAW ( Submerged arc welding )

Would also like to know if any standard Nozzle design is available for Narrow Groove welding.

Thanks.

I'm using Submerged arc wekding for the welding of shell.

Plate matl.:- sa 516 Gr. 70
Thickness :- 100 mm

As mentioned by Carburize i don't have the following book.
"Developments in Pressure Vessel Technology-3" Edited by R W Nichols - Applied Science Publishers - London

Let me know if standard Nozzle design is available for the Narrow groove welding.

Thanks,

galab,
Do you have square wave SAW power supplies or conventional supplies. Multi wire or single wire?
