Welding Aluminium
Unlike conventional aluminium welding techniques, brazing with Durafix Easyweld is very simple. There is only one rod type, which works on all grades and alloys of aluminium.
You do not need to identify the specific alloy or choose a brazing filler to match. All you need are the parts to be repaired, the Durafix Easyweld rods and a heat source. Just follow these four steps for a perfect brazed repair.
Preparation
Brush surface of the part to be repaired thoroughly under heat to break up the surface coating of aluminium oxide.

Heating
Heat the aluminium parts hot enough for the rod to flow without the aid of the flame, thoroughly tinning the surface.
To test for the correct temperature, rub the end of a rod onto the work surface while heating, the rod will flow when working temperature is reached.

Tinning
Brush tinned surface under heat, thoroughly filling the open pores. This creates a film of rod over the weld or repair area, which aids bonding and strength to the weld.

Filling
With sides thoroughly tinned, flow in enough rod to fill the vee. Be sure filler fuses with the tinned surface without melting the aluminium.
