Back in the early 2000s I ran a big old Lincoln DC-600 on a boiler retube in Richmond. That machine was a tank but the arc was finicky with 5P+ rods in tight spots. Last year I did the same type of work on a new Miller inverter and the arc control was way smoother, less spatter and quicker cleanup. Anyone else notice a big jump in weld quality switching to inverter machines, or is it just the rod and prep?
I used to swear by 7018 rods for everything, even stuff where I was burning through rods like crazy on overhead passes. Then my foreman handed me a spool of flux-core wire and told me to try it on a 3/8 inch drum repair. Has anyone else made the change and found it actually saves you time or does it just feel wrong at first?
Been fighting with porosity on 3/8 plate for months. Tried every gas flow and tungsten grind combo I could think of. Finally watched some old dude on youtube just crank his amperage way higher than I'd ever try and boom perfect welds. Turns out I was running too cold because I was scared of burning through. Has anyone else found that going hotter actually cleans things up better?
Been fighting rusted gusset plates on an old water tower out near Fort Wayne for two weeks and after the third plasma pass on a crusty 1-inch plate I realized it leaves way less slag to clean up than spending 20 minutes on a grinding wheel - has anyone else swapped tools just to save your hands on this kind of job?
Saw a guy at a job in Wichita last week lay out a wall with a track and a square, no tape measure needed, and it clicked - I'd been measuring each stud spot like wood instead of using the pre-punched holes right. Any of you guys just mark every third hole and move on?
I was at a job in Tulsa last month and my foreman walked over while I was swapping a tip for the fourth time that morning, he just sighed and pointed at the little cleaning kit sitting in my box. Turns out I was cranking the oxygen way too high and cooking the tip from the inside out, I never even knew you were supposed to adjust the pressure based on the metal thickness. Anybody else find out they've been doing some basic thing wrong for years just because nobody ever showed you the right way?
Picked the 7018 stick over the MIG because the steel was greasy and beat up from years of use. Took me twice as long but the weld held up when they pressure tested it at 150 psi. Anyone else still running stick for dirty repairs?
Fogged up within 10 minutes on a boiler job and I couldn't see a thing. Tried every trick to fix it but nothing worked for the heat. Anybody here found a face shield that actually stays clear when you're welding near steam lines?
I had to choose between stick welding and using a wire feed MIG setup for some exhaust tube headers on a job last month. I went with the wire feed because I heard it was cleaner and faster for thin wall stuff. It turned out okay but I spent a lot of time cleaning up spatter and fighting with the settings. A buddy at the hall said I should have stuck with 7018 rod for better penetration on the joints. Now I'm wondering if I made the wrong call for that specific project. Has anyone else tried both on tube work and had one come out way better?
I used to drag tanks everywhere for structural work but finally got a Hypertherm 30 and holy crap the difference in speed is insane. Has anyone else made the jump and found it saves your back on long days?
I spent 10 years swearing by my old torpedo level on refinery work, thought those digital display levels were just expensive toys for green guys. Then I had to set a 40-foot vessel base plate on a sloped foundation last month and the digital gave me 0.02 degrees repeatability in 3 seconds flat. Anyone else eat their words on a tool they talked trash about for years?
I was pricing out a retube job for an old Cleaver-Brooks last week and compared direct from a mill vs my usual supplier. Markup was 210 bucks more per sheet for the exact same material. Anyone else cut out the supply house for big orders?
I was grabbing coffee at the hall and heard a safety inspector mention three boilermakers died in the last five years from confined space issues during tank cleaning. One guy didn't check his monitor before going in a storage tank in Gary. I've been in this trade 12 years and I admit I've skipped a few steps when I was in a hurry. Has anyone else had close calls with confined space work or seen guys get too comfortable?
Was on a shutdown job up in Gary, Indiana last month... this seasoned pipefitter named Walt watched me lay a bead and just said, "You're fighting it instead of feeding it." He sat me down during lunch and explained how he treats puddle control like a conversation, not a battle. Been doing this for 8 years and never thought about it that way... my welds are smoother now and I'm not burning through rods as much. He told me he learned that trick 30 years ago from a guy on a boiler in Ohio. Anyone else had an old timer drop some simple wisdom that completely changed their approach?
I was working on a heat exchanger bundle down in Baton Rouge last Thursday. This one tube was weeping right at the tubesheet and I just figured I could lay a quick bead over it and move on. Spent almost 2 hours trying to get a clean cover weld on that thing. Kept blowing through because the tube wall was way thinner than I guessed. Finally the foreman walked over and asked why I didn't just use a swell plug. I felt like an idiot. That plug took maybe 3 minutes to set and held pressure fine. Has anyone else had a simple fix take way longer because you were too stubborn to grab the right tool?
I was complaining about a job where the pipe was off by 3/16 and the engineer wanted us to redo it. This guy who's been welding since the 70s just laughed and said he once had to make a 2 inch adjustment with nothing but a torch and a 4 pound sledge. I always figured tighter was better but he made a good point about working smarter not harder when time is money. It's got me second guessing how much I stress over small gaps vs just getting the job done. Anyone else ever have an older hand change how you look at the work?
I'd been running the same Miller 250 for about 6 years straight, thing was beat to hell but I figured it was fine. Then I got a job on a new boiler down in Baton Rouge and the crew lead had a Lincoln LN-25 he let me borrow for a day. First pass on a 3/8 vertical plate and I couldn't believe how smooth it laid in. Burns were cleaner, less spatter, and I wasn't fighting the arc as much. Ended up buying my own Lincoln the next week. Has anyone else switched brands and seen a big jump in quality or was I just stuck in a rut?
I was working a shutdown at a paper mill in Mobile, Alabama back in 2017. There was this old foreman named Ray who had been on the job since the 70s. Every time he saw me he would say 'Hey kid, hand me that 3/4 inch wrench' even though I was 42 years old at the time. One day I finally said 'Ray I got kids older than you.' He just laughed and said 'You'll always be a kid to me until you retire or die.' That stuck with me because boilermakers have their own way of showing respect through giving you a hard time. Has anyone else had a nickname or label that followed them around for years no matter how much experience you gained?
Last Tuesday we were setting a steam drum at the new refinery expansion out in Gary. We had the crane all rigged up and I gave the hand signal to start the lift. About 10 feet up, the wind caught it and the whole thing swung bad. The tag lines we had weren't enough to keep it steady and it scraped against a steel beam. I had to signal a hard stop and we spent the next 45 minutes re-rigging with heavier chokers and adding an extra tag line. My supervisor was yelling at me for not accounting for the gust conditions. Anyone else have a lift go sideways because of weather you didn't see coming?
I picked up one of those no-name auto-drain valves off Amazon for my compressor setup. Figured it would save me time not having to drain the tank manually after every shift. Lasted about three weeks before it started leaking air nonstop. I came out to the shop one morning and the compressor was cycling every 2 minutes because the valve just gave out. Took me an hour to find the leak because it was a slow drip inside the drip leg. Ended up replacing it with a Drain-All brand unit that cost twice as much but at least it's built right. Anyone else get burned by cheap automatic drains on their air system?
I needed a set of carbide burrs for a boiler tube repair last month and didn't want to drop $200 on the good stuff. Picked up a 10 piece set for $35 and figured I'd be replacing them after one job. They actually held up better than I expected on 1/4 inch plate, but I'm wondering if anyone else has gotten decent life out of them or if I just got lucky.
I keep seeing guys grab a mig gun for thin wall pipe. Says it's faster. But at the shop on 45th, we did a pressure test last week. Three mig joints failed at 80 psi. My four stick joints held fine. Same schedule 10 stainless. So is speed worth the rework? Or am I the old timer who just doesn't get it?
I was at a job in Pittsburgh last month working on a reactor vessel. This old hand walks by, watches me grind the bevel for maybe 20 seconds, and says 'you're burning the hell out of that, you need to move with the direction of the roll not against it.' I had no idea what he meant so he showed me. I had been grinding perpendicular to the weld joint instead of following the curve. Felt like a total idiot. Has anyone else had a simple trick like that completely flip how they work?
Been a boilermaker for about 8 years now. I always ground my tungsten straight across like I saw some guys do. Then last month a veteran inspector on a job in Gary pointed out my welds had this weird arc wandering issue. He asked to see my tungsten and just laughed. Showed me how to grind lengthwise with the grain and my beads came out way cleaner. I had been fighting porosity and bad starts for years for no reason. How long did it take you to figure out basic stuff like that?
He was explaining to an apprentice that he just marks the angle with a soapstone and cuts by eye, and I'm wondering if that's a common trick or just a fast way to mess up a fit-up on a boiler tube bundle, has anyone else skipped the gauge and regretted it?
