1. Brazing

2. 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.

3. 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

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

5. 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

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

7. 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

8. 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
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.

10. 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)

11. Stage 7: Allow the work piece to cool slowly

Stage 7: Allow the work piece to cool slowly

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)
