Usually when using brazing to join steel and other metals together, I am working with rods,nails, or other small hardware. The main theme on most of these has been mid century decor with emphasis on square cut nails. It is only through handling of the brazing process that I am familiar with the smoothness of the weld beads. Not have a TIG welding rig, I find brazing especially attractive as a method in construction of more conceptual metal art pieces. Take my latest work in progress for example, I wanted to join thin 16 gauge steel squares and rectangles in a 3D space without having huge welds protruding with obnoxious weld spatter everywhere.
The metal looks dirty and rather unattractive at this stage primarily because of the smoke, heat discoloration, and burnt flux. Once clean, the brass brazing joints will glow gold against the shiny grey steel. This alone will be an attractive finish with a rust preventing lacquer. But there are many other finishing possibilities either covering or leaving the brass weld beads exposed.
Here are a few more views to appreciate the volume of the composition.
