Brazing The Copper Pipe Shorts Short Acservicing Acrepair Weldin Mistake #2: dirty pipe surface. the joint surface areas must be clean and free from oil, grease, or oxide contamination prior to brazing. cleaning the piping to be brazed is very important. a dirty surface prevents the alloy from melting across the entire surface. Apply the heat source to the mating surface when the filler metal completely melts. put the solder somewhat off center at the bottom if the joint position is horizontal. now keep the torch at the base of the fittings and shove the solder into the joint straightly. the joint temperature will melt the filler metals.

If you choose to use flux and solder paste, the process is as follows: apply a layer of brazing solder paste on copper pieces. place both sides together. heat with an oxyacetylene torch until joints are fused – this will take about two minutes per inch or so. if it’s not hot enough for solder, it will just absorb the solder into the flux.
