Using an MF600 CO² laser with an integrated
CNC orbital cutting head we are able to produce an uncontaminated
cut edge which has no significant distortion.
Laser Welding
We have recently installed two Luxstar 100W ND:YAG
laser welding heads, each individually directly and controlled
by six axis robots. ND:YAG laser welding is a low risk
technique with many benefits e.g. high speed, low distortion,
excellent aesthetics, and a small heat affected zone.
A significant advantage of laser welding is that the penetration
is controllable. For example, in the welding of tube to
plate parts for heat exchangers, the tube must not be
perforated, so the weld penetration through the tube wall
is made only partial.
Our purpose built manufacturing unit is provided with
conditioned and filtered air to achieve environmental
control. The ventilation system has been 'balanced' to
achieve the required airflow rates and is temperature
controlled. This allows us to undertake strictly controlled
manufacturing and assembly projects on behalf of our customers.
Our 10,000-class clean room consists of a change area
and the clean room itself. To achieve the classification
five fan filter units are mounted within the clean room
ceiling, and have common speeds controlled via a roof-mounted
controller.
Using a BOC Edwards Spectron 5000X-leak detector we
can offer automatic leak detection facilities to meet
the needs of our industry effectively for both exacting
special application and also throughput production.
In order to meet the most stringent specifications,
such as testing ultra high systems or components our
system enables leak detection down to 2 x 10-12
mbar 1s-1 with liquid
nitrogen. It is also appropriate for operation in high
helium ambient conditions.
