Braze welding is the process of joining two parts of the same or different
metals (butt or angle join) using brass filler metal rods. The metals being joi-
ned do not melt and the rod melts at a lower temperature than the base metal.
The joint is produced cumulatively by film adhesion.
Advantages of braze welding:
It is easier to braze parts equal to or more than 1.5 mm thick than to use an
autogenous welding process. It is a very fast process. The joints are very
strong mechanically and metal distortion is low.
Suitable for thin and thick metals. Filler metal more economical than silver sol-
der.
Constraints in braze welding:
Not recommended for parts likely to be heated to temperatures of around 650-
750°C.
Main applications:
Recommended for iron, steels, galvanised steel, cast iron, central heating pipe
runs, metal constructions in tubes and sections (doorway, garden furniture, flo-
wer pot brackets, etc.), joining forged iron casings (grills, gates, light fittings,
coat hooks), repairing assembled objects (bicycles, pushchairs, go-karts) and
metal sheets (cars).
Implementation:
a) Preparation:
The edges of the parts being joined must be clean, stripped and
degreased.
For parts 0.8 to 2 mm thick: butt joint, no gap (1).
For parts less than mm thick: edges separated by a distance equal
to half the thickness of the part (2)
For parts 4 mm thick or more: butt joint, with 1.5 mm gap. Create a
bevel whilst maintaining a 1.5 mm heel (3).
Wear goggles for braze welding.
