Narrow Groove welding technical details.

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.  

RE: Narrow Groove welding technical details.

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".

RE: Narrow Groove welding technical details.

"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.

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