Silver solder?

[ABI Brewery]

Which silver solder is my best choice for welding a 4" tri clamp to a keg for a fermenter, going to use the current 2" triclamp as a bottom drain..............cant wain to get this project going, I'm going to cut the top out tomorrow and get started

If you're planning on any kind of pressure, finding someone to TIG weld it for you is probably a better idea. Most time silver solder is used with a tight-fitting flared opening and that's going to be difficult/impossible with a 4".

Unless @Bobby_M carries a 4" pull-through tri clamp ferrule I agree finding someone to do a sanitary SS weld on that bad boy is the best course...
