Just how strong is a silver soldered join?
by John
I bought some 6mm x 0.7mm brass strip to hold on wooden lagging on my 6″ vertical boiler. Trouble was that I could find suppliers who had the strips only in 300mm (12″) lengths. So I decided to join 2 of the strips to provide the 450mm lengths that I need.
I have made band saw blades with silver solder, quite succesfully, but the ends were scarfed so the join was over a 5mm or so length of the blade.
I wondered whether I could butt join the brass strips with silver solder, and if so, whether the join would be adequately strong.
At this point I stopped adding weights. I think that the soldered join should hold the wooden strips to my model boiler!
Are you impressed? I am.
45% silver or plumbers (5%) solder ?

Good point. it is 45%.

It looks like you have measured the strength of the join. If you wanted to test the silver solder you could have used just a piece of silver solder rod which would have a easy to measure cross sectional area..

Yes. I should have titled it “Just how strong is a silver solder join?” because that is what I was really wanting to assess.

I have changed the title as result of your comment, thank you. John.

I’m impressed! I didn’t think it would be that strong. Thanks, I learned something today.
