Boiler Welding

Just thought members might like to see this nice welding on a 3" scale ploughing engine boiler, note the small number of stays compared to what are usually used in the UK. Size wise that is about an 8" barrel

That is a tasty bit of welding. Hard to believe it's not done with automatic machinery.

We had one welder who appeared to be almost that quality, but unfortunately we discovered in a crash test at MIRA that she did a fantastic capping run, but never seemed to get the weld to go through the thickness. As a result the bits she did flat-packed themselves on impact with the test block. She is now welding up arty steel bodices for the fashion industry in her spare time & wheelchairs as her day job.

Yes. Very nice. Tig by the look of it and stove pipe action. Laying the weld over itself from side to side. Very hard to do vertically with stick welding but the technique used by boilermakers usually on repairs.

Penetration s everything

Looks like one of my welds (in my dreams...)

Not that unusual to have so few stays on a steel boiler in the UK Jason. My 6" engine with a firebox side plate 16" x 12" only has 16 stays.

Still better than the 90 stays that the original drawings had throughout the boiler, same 5/16" plate but pressure dropped by 10psi to keep within Aussie code.

As the builder said once you start to get upto full size thickness of plate stay spacing can also be the same as full size
