- What rules or laws would apply in Finland?
As I see it, the European Union's rules apply: when a pressure vessel is less than 50 bar-liters (total volume times pressure, approx 150 psi-gallons), no official testing is required. Of course, I'll make a 2.5 x hydro test myself, that goes without saying.
There are no specific rules for building model boilers in Europe that I know of, but there are in Australia, published by the Australian Miniature Boiler Safety Committee, and I've followed those on my previous two projects, where the boilers are silver-soldered. Also, I re-test my boilers to 1.5 x working pressure every year.
- CuNi is prone to crater pits and crater cracks if you pull the arc out too quickly.
The TIG welder I'm looking at (GYS 160 HF, made in France) has an automatic, adjustable ramp-down of the current. That should be adequate... ;-)
Thanks for your replies, any and all further comments are appreciated.
