5 and 6g pipe cover pass

admin

I'm struggling to get my cap pass below the 1/16" max reinforcement. Its 2" schedule 80ASME pipe test and I'm using 3/32 7018 rod around 85-90 amps for the cap pass. Its the 2-5 o clock position I'm having trouble with with both 5 and 6 g, Top and bottom are fine. I'm keeping a tight arc and the rod looks like its running dead center thru the pipe. I'm using a side to side weave about 1.5 rod widths when running stringers on the 6g and a full groove width weave when capping the 5G. If I speed up I tend to get undercut on the sides. What weaves do you guys use when running the 3 and 6 oclock areas as thats where I tend to get too much reinforcement,which is between 1/8 and 1/16 inch. Do you weave or manipulate the rod any when doing the cover pass on the 6g with stringers?  What amperages etc Thanks in advance.
Reply:I use a very slight weave when capping, even with stringers. Everyone does whatever works for them.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720

Reply:ya 1/16" is a little over the top. 1/8" for the root and cap is acceptable. Work on taking your fill pass just below the the top of the bevel, you may have to adjust how high/low you take your fill pass heighth wise. In doing this you will be able to lower or heighten the profile of your cap. If your not used to speeding up and going fast id suggest "making the rod work for you" and take your fill pass lower than usual so your making the rod fill more. If your comfortable with speed and the rotation involved with 2" pipe keep your fill just slightly below flush and giver with a nice fast weave.
Reply:Everywhere I have tested or welded it is 1/8" also for root and cap. I use a z-weave for caps and keep my travel angle very shallow at about 10degrees. When I hit the sweet spot they are very uniform with less than 1/8" reinforcment.

Reply:Thanks. I wish I could see a video of someone setting up and achieving no more than 1/16". I'm told AWS allows 1/8" or less reinforcement on the cap but am being told ASME is 1/16 or less on the cap. I sure would like to see it in print. I'll keep working on a weave with a faster progression. I had a old timer tell me today to make small circles and keep the rod straight. Another guy told me to rock the rod not whipping but changing the angle from straight thru the center of the pipe and tipping it back about 10 degrees the back to straight. I'm not sure about that technique but i think the little circles will allow me to travel faster than I am presently.
Reply:Depending on which ASME code you use, it varies.  In B31.1, acceptable reinforcements range anywhere from 1/16" maximum up to 1/4" or more depending on the design temperature and the thickness of the component.
