i dont know what youre wanting to join (cant see the photo) but if its such a weak joint that you would consider solder, you might want to have a look at adhesives, as some of them can be very strong. if you have a large contact area may be able to create a bond stronger than what's sticking out.

i think one of the little lotus sports cars has its chassis glued together, rather than welded.

i dont know what youre wanting to join, but id think its got to be easier to turn up a ring of steel and fasten it with a grub screw?

julianf · « **Reply #24 on:** February 17, 2013, 11:47:05 AM »

...or just glue it (silkaflex, or just aryldite etc). If its just a fishing rod, its not heavy. Or are you talking about the fins at the bottom?

You could silver solder/braze with the torch and MAPP gas but you would have to ask James if its suitable for the metals

When you say iron in the OP, do you mean mild steel? Mild steel and stainless steel will silver solder very well. In the past, I've used the same rod and flux as I use for copper.

yes maybe mild steel?

yes to botom fins i need to weld those fins on a stick this part gets pushed in the ground

Head Womble · « **Reply #28 on:** February 17, 2013, 01:12:03 PM »

Why do you need the fins ?

Is it to stop the buggers twisting ?

And what's this got to do with bio/veg ?
