BS EN 13133 governs brazing (ie silver soldering) procedures. The recommended degree of overlap for a brazed joint is 3 - 4x material thickness.
Re rivets - these can effectively remove the joint gap. No gap = no joint and can lead to you effectively building a crack in the joint. Separate the components with small pieces of foil prior to rivetting.

I think he means copper foil.

I think he means copper foil. Kwil He could mean silver solder foil. I've used it myself to create the necessary gap. Bit fiddly though, and fluxing can be a problem. Mind you, I was probably doing it wrongly anyway! JB

Silver solder foil is available from CupAlloys.
Useful in some cases, but to ensure there is a joint (for the SS to flow into) I space items apart using pieces of old rusty feeler gauges.

Re the foil. Sorry for the ambiguity I meant silver solder foil. It melts as you make your joint helping to ensure good penetration.
