I had some pipe to play with today so figured what the heck. Lets play with the mig a little bit. This is some pipe work used in Agricultural irrigation systems. 8" Galvanized .120 wall The galvanizing on this stuff is next to impossible to get off, but I have found that a disk designed for aluminum works pretty well for cleaning it off. Its a low pressure pipe. 80-120 psi. Only specification is it can't leak. I usually do this with a 6010, but Figured I would take the mig and do one in a fixed position on the stands, and the next one where I could roll the pipe. Machine is a Lincoln Powermig 255 on 75/25 with .035 70s-6.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:first one I welded uphill without rolling the pipe. You'll have to excuse my ignorance. I don't work enough pipe to know the position names. Second one I rolled as I welded around the joint.Finished, pressure checked and loaded on the truck ready to head out to Florida in the morning....

Reply:looks good!
Reply:Great work, again. I've got some heavy galvy stuff around. I normally just fight with it as condition of using free iron. The other day I tried a stainless disc,, no significant change in results. I tried a concrete disc,, no significant change in results. The one thing I haven't tried is an aluminum disc. I just don't have a reason to have one around. Dern.
Reply:Well the Galvanizing on these pipes and fitting is very thick. You can actually grind it off and then heat the area with a torch and the glavanizing will flow onto it from the surrounding areas. The problem I was having was that the disk would clog up and quit cutting. An aluminum disk won't load up with the Galv. like the steel disk do. I actually ran across it by mistake I grabbed the wrong grindr, and thought, dang this disc is cleaning well. then I looked and was like maybe I should try that again. and it seems to work pretty well.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:Jeez, stick and TIG and MIG? You -are- a multiprocess-man! Nice work Jackson, but you still don't take as good a picture as Zap. Try macro/micro mode on the camera. It's often the mode with the flower icon for it. (no joking there, newer digital cameras usually do have the flower icon for close-up/macro/micro mode).And you left out the coin in the picture, for scale reference ya know.
Reply:thanks for the compliment Moonrise. This camera doesn't have a close-up feature, but for $50 what do you expect. A better camera is on the list to get when I head back to town shopping this weekend...I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:Nice work. Mig is FASTER. I do a lot of galvanized cell towers. All the galv has to come off for a nice weld. All welds are visiual AWS inspected. I only use aluminum disks now because they don't load up and grind carbon steel like crazy. Where I buy the aluminum disks, they cost the same for a box of 25 4.5" as the type 27 steel ones. I also use a die grinder to get rid of the galv with an aluminum TIN Bit. Works the balls.ONCE I got too much galv fumes. Never again.DavidReal world weldin. When I grow up I want to be a tig weldor.
Reply:Looks good.. Dont forget to record your mileage.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Hmm, I always just used intershield or dual-shield for galvanized steel. Boils it out nicely. Wouldn't work with solid-core wire.Very nice looking welds man! :bow: |
