Thats a good indication that brazing material flowed where it was needed. The higher the silver content the stronger the bond but the hotter the temperature needed to melt the filler metal. Brazing in air with flux. Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal.

You can use any silver solder but you will need an acid based flux specifically manufactured for nickel or stainless steel. All i had on that day was a cutting torch but it allowed for a soft enough flame to get the job done. But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod.

You can see a nice collar of silver brazing material on the head of the stainless steel bolt when its done.

The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. The brazing process can yield strong joints that are ductile clean and smooth. The joint will only be as strong as the silver solder itself. Use a torch that produces a high intensity flame.

Brazing copper will provide a stronger bond because of the high of silver in the brazing rod. Technically you can either braze or solder though you cannot braze with solder or solder with brazing rods.
