Hi all, can anyone tell me the industry procedures for the above coding?

What gap, root land and so on should i be using? Also how far from the bevel should the restrictor plate be?

Assuming you are welding carbon. I have done a few of these. The ones i did were one side beveled the other side flat (cut straight) 5mm gap 1mm landing edge restriction disc about 2 inch away from your butt. phillips 56s root fill and cap. Rooting with 3.25, hot pass with 3.25, and away ya go.

When your rooting a slight longer pause on the flat side.

Spot on gapstobig with everything except restrictor plate.

As far as I can recall the ring is positioned about a half inch from the top, square edge!

Not much of a restriction at 2"!

The restriction flange is placed half an inch max away - http://www.weldingdata.com/pictures/6grPic.jpg

The tests i did was heavy wall and always 6" and above. A 5mm gap was needed to get the correct pen on the flat side, If you used a 2.5 it would take you for ever because of the obvious size and the pausing on the flat side, You would do well to get an inch out of it, loads of stops and starts. If you set a smaller gap to cope with the 2.5 rod, you wouldn't get the correct pen on the flat side.

5mm gap 1mm landing edge, dc neg 3.25 about 120 amps

I may have gone with a 2.5 on 2", but then i never tested on anything under 6" heavy wall, 6GR with a restriction disc

You've got the square part of the single bevel prep to work off,which disperses heat,allows pool control etc
