how to weld pipes/tubes?

admin

is there a good practice out there for welding a pipe to another in a T fashionmening i notched one pipe so it intersects another to form a letter Tbut as far as welding it goes i cant seem to get the hang of getting a good bead out of it.and thats mostly due to the fact that welding around the pipe requires having to constantly change your position and start and stop constantly to get the other sidesso is there a tutorial out there that explaines a better method?
Reply:The welders lens has a pretty good tutorial for welding pipe like you describe.  Michael Treadway is the author and does a pretty good job describing the process and what to do when it starts going wrong.  I have a couple of his series and they are pretty good.BobI'm spending my Kids inheritance, I dont like him that much anyway!!!!!!Enuff tools to do the job, enough sense to use em.Anybody got a spare set of kidneys?  Trade?

Reply:Many folks make a template using a pipe/tube with a cut hole that fits over the pipe/tube that you want to cut. It works fine for both plasma and torch cutting. Other folks here buy and use a pipe/tubing notcher.Co-Own CNC shop:Miller :1251 plasma cutter, MaxStar 700 TIG/Stick, & XMT 456 Multiprocess Welder.&  2 Hypertherm HPR260's Plasma CutterSorry I had a bad stroke but now I am back.

Reply:I have notched and welded a few test pieces myself and have ugly welds but hold up to the sledge hammer test.  From what I have learned it takes time under the hood to get it right.  I am welding 2 3/8 pipe for a fence and have to start and stop my welds to get around the pipe on all sides.  Next weekend I will be doing the real thing.
Reply:Stop and start as you need to in order to stay in good position. Making good stop and starts is just another required skill.Tough as nails and damn near as smart
