This week we have been mostly welding flue tubes for 45305. We had Malcolm-the-Welder visit the shed to weld the bottle ends onto the new tubes ready for threading and re-inserting into 45305’s boiler as-soon-as.
Malcolm commented that the tubes “weren’t a problem to weld because it’s only low pressure”. Yes, my friends, to Malcolm, our 225 psi boiler is small beer, in his career, Malcolm has welded power station boilers and nuclear reactor boilers with pressures measured in thousands of pounds per square inch and with tube walls 3” thick. So our superheater tubes are small and low pressure to him, although having lifted each of them onto and off the welding stand and then carted them out of the shed through the machine-shop-slalom I beg to differ, they started big and heavy and got progressively bigger and heavier as the job went on. But it’s all done now, thankfully. The tubes are stacked ready near the door to the machine shop ready to be whipped into the lathe, threaded and whisked out again.
A big thank you to all the people who helped with the job, Thanks Guys, you know who you are.
p.s. Despite two whole days spent on the welding job I completely forgot to take a single photo, so you will just have to imagine the beautiful straight, even smooth welds. Thanks Malcolm.
