I was poking around Gary Iron & Metal looking for some scrap pipe flanges and stumbled on these old Heine boiler drums sitting in a back lot. They were stamped 1927 and had these huge riveted seams you just don't see anymore... made me think about how much stronger stuff was built back then. Has anyone else come across old boilers like that in a salvage yard lately?
I had this job patching up a boiler at an old paper mill outside of Richmond. The steel was wet and greasy no matter how much I preheated or ground it down, and I was stuck choosing between 7018 rods for strength or 6010 rods for that deep penetration on dirty metal. I went with 6010 because I needed to burn through the crap on the surface and get a real root in there. Ended up running the whole six passes with 6010 at around 90 amps, and the welds held up after the hydro test. The spatter was a nightmare though, I spent an extra hour chipping and grinding compared to using 7018. Has anyone else had to swap rods mid-job because of wet conditions or rust?
Been using the same tub of flux for like 4 years and just read on a Grainger forum that some old fluxes have ammonium chloride that corrodes joints from the inside over time. The company I buy from said 2 out of 10 fittings on a hot water line can fail inside 5 years with that stuff. Anyone else check their flux dates after reading something like that?
Been fighting with TIG welding these thin stainless panels for a local food plant. Finally dialed in the gas flow and travel speed just right around 3pm and it laid down perfect. Anybody else find themselves chasing that one setting for weeks before it clicks?
One of the support welds gave way while a guy was lifting a heat exchanger tube bundle. It wasn't overloaded, just a bad weld that looked fine on the outside. Has anyone else started doing dye penetrant tests on all their crane attachments now?
Night and day difference on 3/8 plate, the weld laid in so much cleaner with way less spatter. Anyone else made the switch and never looked back?
I was picking up some fittings at the supply house on Wednesday morning when I caught two old-timers chatting. One says to the other 'my boiler's got a personality, it only acts up when I'm alone.' At first I laughed, but then he went on about how it would hold pressure fine all day until he was the only guy on the night shift. Made me think about how many weird little quirks we just accept in old equipment instead of actually tracking down the root cause. Anyone else got a machine that seems to know when nobody's watching?
I remember my first boom truck weld test back in spring of 2023 down at the Local 374 hall. I must have ground out half my beads after the inspector pointed out porosity and undercut on every pass. Fast forward to last month, I took the same test again (same inspector, same machine) and passed first try with no repairs. The big difference was switching to a 1/8 7018 rod and slowing my travel speed way down. I also started preheating the plate to about 200 degrees (which nobody told me about the first time). Has anyone else seen big improvements just from changing rod size or preheat temps?
After 8 years of using the same bare metal handle I stole from my dad, my elbow was screaming... so I grabbed a $15 one from the supply house and my arm actually stopped hurting by lunch. Has anyone else swapped their old hammer out and noticed a real difference?
I had this guy named Jerry at the hall look at a bead I ran on some 1/4 plate and he straight up said it looked like pigeon tracks. He told me I was moving the torch too fast and my angle was off by about 10 degrees. I slowed down my travel speed by half and tilted the torch to a 20 degree push angle instead of 30. Did a test piece right there and the bead flattened out and Penetrated way better. Has anyone else had an old timer call out a bad habit you didn't even notice?
Was working on a 6 inch pipe last month over in Baton Rouge and skipped the full purge step cause the foreman was rushing us. We fired it up and the weld blew a pinhole about 3 hours later. Had to cut it out and redo the whole section which took an extra 8 hours on site. Now I ALWAYS double check my purge flow even if the boss is yelling. Has anyone else had a weld fail cause you got pushed to skip steps?
I was working a big project at the BP refinery in Gary, Indiana last month and somehow cranked out 1,000 welds on a single pressure vessel job. Some guys say you should never rush past a certain number per day, but I was averaging 25 solid passes and only had 2 rejects. Do you guys focus more on hitting a high count or are you all about slowing down no matter what the foreman says? Curious how others balance it when the schedule is tight.
I always figured welded seams were stronger hands down but seeing those triple-riveted joints from 1910 still holding tight after 100 plus years made me wonder if we traded longevity for speed with modern methods, has anyone else seen old riveted work that held up better than expected?
I was out at a plant in Gary last month scrubbing a condenser tube sheet with a wire brush and getting nowhere. A older guy I was working with handed me a scotch brite pad wrapped around a putty knife and told me to use a drill with that. Cleaned the whole sheet in 45 minutes flat instead of the 3 hours I usually spend. Any of you guys ever tried that or got another method that works better?
Bought some no-name auto-darkening hood off Amazon for a pipeline job in Odessa. First day out, the lens fogged up and the sensor failed after two hours. Anyone else learned the hard way not to cheap out on PPE?
We were welding up a feedwater heater at a plant outside Houston. Everything went wrong from the start. My stinger cable shorted out on a steel beam around 9am. Then the inspector flagged our root pass for porosity right before lunch. By 2pm the grinder seized up and I had to borrow one from a guy on the other end of the unit. To top it off, one of the guys dropped a beam clamp on his boot and we had to shut down for an hour. Has anyone else had a day where every single tool and person fought against you?
Had about $900 saved up for a new welder last fall. I was stuck between a cheap TIG setup and a decent flux core machine. Everyone online said TIG is the way to go for clean work. But I do a lot of outdoor repair jobs on trailers and heavy equipment in the yard. The flux core handles wind and rusty metal way better for me. Six months in and I've burned through 3 spools of wire on farm gates alone. Has anyone else skipped the fancy stuff and just stuck with a simple wire feeder for dirty jobs?
Got the Lincoln Viking 3350 after a buddy swore by it. Worked great for the first three weeks, then the sensors went haywire. Keeps flickering on me mid weld, especially in bright sunlight. Tried adjusting the shade settings and cleaning the lenses, nothing helps. Anyone else have issues with auto-darkening hoods acting up after a few jobs? Thinking about just swapping back to a fixed shade.
Was working a turnaround at Motiva in Port Arthur, Texas. We were using a 300-ton crane to set a boiler drum when one of the lift straps just let go. Dropped maybe 2 feet before the backup caught it. Everyone froze. My foreman started yelling to stop the lift. I kept the crane steady and had the riggers swap out all the straps with new ones before we went again. Took an extra 2 hours but nobody got hurt and the drum was fine. The internet says you should always inspect straps before lifts, but in the field you get rushed. Anyone else ever have a close call like that on a big lift?
Six months ago I was chasing 3/32 gaps all afternoon on the same type of work, and now things just click. What was the one thing that made your welding suddenly feel smooth?
I was just flipping through my logbook for a job inspection and noticed I passed the 1,000 weld mark without even realizing it. That number surprised me because I started this trade three years ago barely able to run a bead on flat plate. Most of those are structural welds on water tanks around the Midwest, so I guess the grind adds up faster than you think. The funny part is I snapped a photo of the page to show my wife and she just said "cool, can you fix the kitchen stool?" Anyone else hit a random milestone that caught you off guard like that?
Back in 2018, a 30-year journeyman named Dave stopped me on a job at the Marathon refinery in Detroit and said my bevel prep was creating stress risers that'd crack in 5 years - I argued with him for 20 minutes before I checked the manual and realized he was dead right. Has anyone else had a veteran call them out on something they thought they knew, and did you change your approach or stick to your guns?
Back in 2019 I was working a turnaround at a refinery in Baton Rouge. This guy named Earl, been a boilermaker for 35 years, walked up while I was fighting with a stud that kept galling. He said "quit fighting it and hit it with a candle first" and handed me an old birthday candle. I rubbed it on the threads and that stud went in smooth as butter. Has anyone else got a weird trick like that from an old timer on a job site?
I was working on a propane tank down at the Port of Savannah last Thursday. Had to drill 16 holes for a patch plate on a curved section. My mag drill kept slipping off the curve no matter how tight I set the magnet. Ended up having to tack weld a flat plate on first just to hold the drill. Anyone got a trick for keeping a mag drill from sliding on a curved surface without having to weld something on first?
