  • How many weld passes to weld pipe

    Having coffee this morning at the local round table, the local retired union plumber asked me how many weld passes does it take to weld a pipe, I asked him what size pipe he was referring to, he said it doesnt matter, I said yes it does, all he could say is that I'm wrong and dont know what I'm talking about.

    You should have asked him how many turns to screw a fitting onto a pipe. It doesn't matter right? LOL...Bob

      Next time ask him how many feet of pipe or tubing does it take to plumb a building. Size of the building doesn't matter, number of bathrooms, sinks, or anything else, doesn't matter.

        If he hadn't already passed away, I'd think you might have been talking to my father-in-law. Wonderful guy but he just lived to argue such things. I can still see the look of firmness he would have had on his face when asking that question. :-)

            The answer is "As many as it takes"

                  Depends on the size and schedule of pipe and the position your welding the pipe in. A horizontal weld gets a 5 stringer cover pass with either 3/32 or 1/8 7018 depending on the size pipe, a root and fill passes...again depending on the size and schedule of the pipe. .....a bell hole weld gets a root pass, hot pass, and then fill passes again depending on the size and schedule of the pipe. keep fill passes just below the top of the pipe so both edges of the weld are visible. The bell hole cover pass is one half rod over the edges of the pipe.. Mig I don't know....
