Hi friends,
I need some welding techniques for the below issue.
we have pipe spools of 1"& 3/4" with pipe to valves.
Can any body suggest me, how to prepare for welding with pipe to valve.
All joints are socket welds.
1. whether I have to keep the valve in open or closed condition?
2. whether I have to remove the gland from the valves during welding?
Kindly suggest me, if there is any procedure for this process?
Thanks and regards,
