I have a combi boiler system that is normally pressurised to 1 bar and a radiator has suddenly developed a tiny, approx 3/16", hairline crack around a spot weld. The radiator otherwise appears in very good condition with no signs of rust but it is a non standard size that would be inconvenient and expensive to replace.
I have tried using two types of epoxy resin sealants but they have both failed.
Is it possible to make a solder repair and if so is there a special solder needed or is there any other reliable solution? The crack is so small that I feel it really should be possible to repair it effectively.
Many thanks
