What type of weld/braze is this?
(OP)
There are two types, brass/bronze to stainless steel, and brass/bronze to what appears to be a copper tube. I'm trying to find suppliers with similar capabilities, but I don't know what kind of weld/braze this is, so I don't know where to start.

debun,
Can you tell how hard or scratch resistant the filler metal is?
A lead/tin based solder will be extremely soft while a high temperature solder will be appreciably harder.
MintJulep,
i don't know if you have ever seen a solder with
Cadmium used but this has that look of a Cadmium based solder metal. Do you are anyone else have an opinion?

Were it my project I would just specify what I wished and put that out. Specifying the materials and the use, especially temperature and pressure, should do it unless it is highly unusual.
It almost looks like a braze alloy between the top part and the bottom assembly and solder between the bottom parts.
Should that be the case then you assemble the top part first at a higher temperature then the bottom parts at a lower temperature.

For a brass/bronze/copper base metals the typical fillers would be copper-nickel unless there was something special about the joint.

FYI, Brazing is above 840° F, Soldering is below that. Alloying ingredients control this transition stage as well as joint properties.
