Bronze Fabrication
|
| One
area where things have developed significantly
over the past few decades has been the development
of welding techniques and materials. We are now
able to weld bronze. Not just braze it, but join
it by melting and fusing a filler rod of the same
composition as the parent metal such that the join
is visually and mechanically seamless. Not all
bronzes can be welded – gunmetal for example
when heated forms a skin of lead on the surface
which is mechanically very weak. But phosphor
bronze is eminently weldable. Fabrication enables
us to use materials effectively and to make
components which might otherwise be prohibitively
expensive if casting patterns were needed. It also
has the great attribute that castings and
fabricated components can be combined into one
assembly, allowing us to get the best of both
worlds.

| We can't take credit for the design or the
woodwork, but we did make the bronze fabrications
involved. |

| Door and window components often
need a combination of pieces, cast, wrought and
fabricated |

through many variations before this - the final
outcome. |
 |
| In this case, part of the work comprised a
fabrication made from separate castings - seen in
progress here |

section - in this case to save weight and cost |

| A simple wrought bronze handrail, patinated and
waxed. |
 |
| Components for a set of portlights - rolled from
strip, welded and then a thread machined on. |
 |
| Brackets for a conservatory. Cut from sheet and
welded up, it is a good use of material, and
avoids the delay and cost of patternwork. For this
sort of application, a brush finish seems
appropriate. The pieces will naturally patinate to
a mellow brown. |
 |
| Listed buildings may or may not get a better
class of pigeon, but they certainly get a better
class of pigeon deterrer! These were fabricated
because it was felt that casting such a delicate
shape would be unreliable and/or weak. |
 |
| We can work quite delicate sections - though one
has to bear in mind that bronze is not as stiff as
steel, and so may wobble a bit more. |
