It all begins from either recognized line drawings or customers sketches which we draw onto our CAD program and convert to G Code. This then allows our CNC plasma cutter to cut the flat sheets including wrappers and barrel, leaving only weld prepping before forming and welding.
We follow the BS EN ISO 15614-6:2006 welding procedure, and as our process is different from the conventional silver brazing technique, we do not require flanging of plates, so nothing needs annealing.
We use copper filler wire which is close to the parent material, including extra deoxidising elements. This allows us to construct the boilers in a way that other methods cannot, due to the local heat input.
Existing TIG welded joints; we will not undo any of the existing work through overheating. Stay arrangements are followed from recognised designs, but we also have safety guidelines in which we can cross-reference with to ensure adequate safety factors are met for the intended design pressure at that shape/size of the vessel.
We still braze the bushes in. These are machined from 'PB1' phosphor bronze, which, although with a high content of copper are capable of being welded to the boilerplate. However, we opt for brazing to BS EN 13134:2000 with 55% silver, allowing the option of replacing bushes if threads are stripped later in its life.
Of course, with the rest of the vessel being welded, we do not find ourselves chasing cracked silver joints around as most of our customers will be all too familiar with.
Conforming to 2014/68/EU pressure equipment directive, all our boilers go out the door bearing CE marks (where required) and conformity and hydro test certificates to twice working pressure which is valid for the life of the boiler unless modifications or repairs that are integral to the vessel occur.
CNC PLASMA CUTTER
It all begins from either recognized line drawings or customers sketches which we draw onto our CAD program and convert to G Code. This then allows our CNC plasma cutter to cut the flat sheets including wrappers and barrel, leaving only weld prepping before forming and welding.
SPRAY BOOTH
Our state of the art spray booth can cope with large and small pieces and is adaptable to all coatings. We can precisely control the flow, electrostatic charge and coating thickness to achieve precise results.
POWDER COATING OVEN
Precise temperature control and large capacity means that we can coat and cure even the largest pieces. We control the entire manufacturing and finishing process and guarantee results in ways that competitors and individual service suppliers cannot.
MACHINE SHOP
Our machine shop is fully equipped with all the machining equipment you will ever need, with a full complement of lathes, forming, creasing and CNC milling machines.
RESPONSIVE CUSTOMER CARE
True Fusion Group conform to customer demands and applicable statutory and regulatory requirements. This endorses our commitment to the quality of our work, products, systems, procedures and services. We also provide other services that compliment the fabrication side of the workshop. To name a few this includes vapour blasting, CNC plasma cutting, chemical etching, powder coating, alloy wheel repair and fork straightening.
