pipe welding ( same as my introduction)

admin

I just started practicing for pipe certification and got into an argument with a buddy. I'm practicing on a butt weld set at a 45 degree angle ( I believe the term is 6G??? not real sure.) and I'm running my cap with 5/32 7018 ( until I can afford some 8010's) and I can't keep my weld from sagging. anyway my friend say's I have to run it downhill & I say uphill. Either way, how do I keep my puddle where I want it? Rowdy
Reply:Hi Rowdy,  6G is the right name for that position, 7018 should go uphill. It's hard to explain on a computer but think about the water line, water doesn't fall on an angle and neither does molten metal!                                                    If this is any help go across the prep, also make sure                   you push the rod uphill.  Good luck                        /-----/         Stephen
Reply:basically the same as the 5G position except the rod angle. Have the rod angle about 10-15 degrees and about 15 degrees to the side. So now you have the rod pointing towards the upper bevel. When you do your weave pause at the top edge only. This will ensure enough deposit and no undercut.Im only an apprentice, but this it what ive learnt so far from the journeymen pipeliners. It works for me
Reply:Thanks Gents, I'll give it a shot and see how it goes.Rowdy
Reply:First off what thickness of pipe, sch. 40 or sch. 80 or sch. 160. Second what size pipe, 3" or 6" or 8" ect.  This will help to determine which rod to use ie: 3/32, or 1/8, or 5/32. This is the same type of test most union pipefitters have to take to get there card. It's normally a 6" sch. 80. At least when I took my test for local 597 it was. To keep the weld from sagging if you can run your weld with a tight arc and keep your rod/puddle in the horizontal position as stated above, and keep your speed even you should be in good shape. But the best way is to ask question as you did and practice each way your told until you find which one is easist for you to master, it should only take a few rods. Oh by the way E6010or 5p is for the root pass and 7018 or low/high is for the hot pass and cap. hope this helps.The only STUPID question is the one isn't ASKED!!!!!!!!Brett B & B Fabrication and Welding Inc.Spalding, MI.
Reply:When i tested it was sch.80,8 inch 6G position.Iused 1/8 6010 around 80 amps for root,3/32 7018 around 90 amps for the hot pass,then back to 80 amps,using 3/32 7018 for the fill and cap.My procedure called for either 3/32 or 1/8 6010 and 7018 rods[my choice].Now in the real world i set the machine inbetween 80 to 85 and never touch it.Good luck
