Would love to be a pipe welder out in the west but don't ever see that happening, beings I'm 31 years old and have had zero pipeline work experience under my belt. So i'll just live out the fantasy at home practicing on some pipe but not exactly sure what schedule and sizes to get. Maybe one of these days they'll run a pipe line near me.93 Bobcat 225GMillerMatic 135HF Tig 91811
Reply:12" sch. Std and 2" sched 80. Get proficient at those and you can weld just about any pipe
Reply:I'd have never been able to afford to buy the amount of pipe I butchered while becoming just adequate at making that downhill root pass.The tank shop I worked at was glad to have us cut up the drops to practice on.
Reply:Have access to a pipe threader and 2" sch 80 ? Bevel, landing and gap make all the difference. Throw pipe in threader grab a grinder leave pipe in jaws sticking out find your angle and hold grinder still as you run threader. Near perfect bevel fast. Make 2 dozen and only root them. Rinse repeat until happy.Sent from my SPH-L710 using TapatalkUsing Tapatalk
Reply:Root rod maybe 5p's 6010 1/8 if using auto hood it should go light, all sparks and light inside pipe. Listen to the sound of your pipe. Dont be scared. Sent from my SPH-L710 using TapatalkUsing Tapatalk
Reply:Tech school uses 8" pipe for training. Not sure the wall thickness right now.  My guess is they choose 8" for a couple of reasons. One it fits in the Ellis saw for cutting into useable lengths. Two the smaller pipe is less expensive to buy, so they get more use per dollar vs going to say 12" pipe. 2" is a useful size, but really poor to learn on. With bigger pipe you have more time to adjust your rod or torch angle while welding. With small pipe/tube like 2" you need to really quickly adjust your angle. During the day, they have guys get the basics down 1st on flat material in all positions. If you can't make decent welds in all 4 positions on flat, don't waste your money on pipe. When they can get that down, they move to the 8" pipe and start the basics with rolled pipe. Then they transition to 2G then 5G and finally 6G. When they get that all done, they drop down to 2" pipe and do it all again..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan
Reply:I agree 2" is bad to learn on but once you have the concept of  downhill welding figured out 2" will teach you a lot about heat control and rod sizes. I personally like 12" better to learn on because it gives you more side and bottom than 8" does although 8" is also a good choice. It should be said that you should practice on the largest pipe available to you for the best price or free(within reason-I'll give you 40ft of 24" but good luck handling it). Then work on 2" last don't be afraid to run a 3/32 bead in the 2"
Reply:Was curious about the 2" sch. 80.  All the 6010 tests I've done were uphill on heavier wall.  Did a search and found UA-8 is done uphill on the lighter 2'' sch. 80.  Is there a common 2" sch.80 downhill test?Last edited by OldSparks; 03-08-2014 at 10:41 AM.
Reply:6" & 2" sched 80 6g is pretty common
Reply:Idk about pipeline work but I'm a pipe welder(different than pipeline) and by FAR the most common tests are done on 6" schedule 80 and tube tests on 2" schedule 160Sent from my iPhone using TapatalkUsing Tapatalk
