Got called out on my weld prep for a 6-inch steam line
I was fitting a new section in a plant near Toledo, and a foreman from another crew walked by. He pointed at my bevel and said, 'Your land is too thick, you're asking for lack of fusion.' I'd always left about a 3/32 inch land, thinking it helped. I tried his way, grinding it down to a sharp feather edge, on the next joint. The weld puddle flowed way better and the X-ray passed first try. Do you guys keep a sharp land or a thicker one for your high-pressure pipe?

My old foreman in Detroit swore by a 1/16 land for schedule 80.

Ever run into issues with a feather edge getting too thin during fit-up? I've had it blow out on the root pass before, so I stick with a small, solid land for control. What wall thickness are you working with on that steam line?
