Brazing

Brazing Brazing is a process suitable for joining pieces of mild steel (ideally of similar thicknesses). The process relies on the use of a brass filler rod which, when molten, is drawn by capillary action into the small gaps between the two pieces if steel.

Brazing This method of joining metals uses very high temperatures (around 900 C) and produces a strong joint with minimum distortion of the original work pieces

Brazing (equipment required) Flux Goggles Gloves Brazing Rod (Made from Brass) Emery Cloth Work piece

Brazing Stage 1: For successful brazing the both parts of metal must be cleaned thoroughly all rust, paint, grease and oil must be removed. This can be done with an Angle Grinder, File or Emery cloth

Brazing Stage 2: Apply Flux. The flux helps clean the metal and has two purposes 1. To prevent the steel oxidising. 2. To dissolve any oxides already present

Brazing Stage 3: Place the work piece on the forge. Safety : Always check that the bricks on the forge are cool before you touch them

Stage 4: Heat the work piece up to cherry red stage. Brazing Hot Enough Too Cold Stage 4: Heat the work piece up to cherry red stage. (Make sure both pieces are evenly heated)

Brazing Brazing Stage 5: Heat the tip of the brazing rod up and dip in Flux The bend on one end of the Brazing rod will let you know what end is cool and safe to hold.

Stage 6:Touch the tip of the brazing rod along the join. (If the work is at the correct temperature the brazing rod should melt without help from the torch)

Stage 7: Allow the work piece to cool slowly Brazing Stage 7: Allow the work piece to cool slowly

Brazing Stage 8: Clean any flux residue ( This can often be done with water however it may be necessary to use a wire brush to loosen the residue first)
