Brazing with oxy-fuel is fun but I'm pretty stoked about learning TIG... looking forward to lots more conversations in this thread. |
Beautiful looking, but there could be a problem with them. Brazed joints work very well when stressed/loaded in shear (lap joints), but not so well in tension. Tension is where welding shines. Your lugs
appear to me to relying on the tensile properties of brazing, and they may fail.
Well made brazed joints have lots of overlap/shear area, as do well made adhesively bonded joints.
