   a) edge preparation will be double bevel with a groove angle of 60 degrees.
   b) what will be the suitable SAW electrode size to increase welding deposition.
   c) ranges of required inter-pass temperature

The Lincoln Procedure Book of Arc welding has excellent tables, charts and will give you this and more information such as volts amps and travel speed.

Thanks Flux.

But I tried and could not able to find any of those tables and charts that you've mentioned in their website.

Mark Anthony Nofuente,
This is a book that can be ordered off their site. It is quite possibly The Most welding information that can be had for $25 USD.
Every Community College and Trade School Library with a welding department I've ever been to has at least 1 copy on their shelves.

Mark,
if the book is sold for 25 dollars, it's obvious they won't put it in their website to be unloaded for free.

I didn't look up your particular query but Super is correct about that book being a very inclusive resource for just about anything 'welding'. Mine is an older copy(70's I believe) that I need to update because some areas have definitely changed as to procedures. But you can't go wrong to have that on the shelf.

Have a Great Day, Brent

Here's the web site.

Other than what Lincoln has to offer, you might want to consider retaining the services of a Welding Engineer.

The Procedure book of arc welding is presented to the public for basically the printing and binding costs. The information you get is "free". All that R & D contained within its pages is the best bang for your buck anywhere in the industry.
