INFO: Weidmüller is a DVS-certied welding shop and relies on the
tungsten inert gas (TIG) welding process to produce 100 %
reliable joints that are uniform in appearance.
3. Process-compatible welding method
The moveable corners and edges of the sheet are
welded into a single unit in a fully automated process.
They are xed in place with a standardised clamping
mechanism. An inert gas is used on both sides during
the welding process to protect against corrosion.
The sensitive sealing edges are welded manually.
4. Attaching the inner-thread sockets
Conventional
mechanically sealed
inner-thread sockets
are used for attaching
add-on components
(such as a gland
plate) to the enclosure
body. Weidmüller has
developed a unique new
welding process whereby
the inner-thread socket is welded permanently to the
enclosure in just a tenth of a second.
In contrast to conventional joints, the welded joint
created by this process requires no additional sealing
material. This signicantly reduces the harmful
inuences that mechanical impact, excessive torque
and vibrations can have on the seal of the inner-
thread sockets. Laboratory tests conrm a leak-free
connection is maintained with a pressure of more
than 1000 kg ensuring performance even under the
harshest conditions. (IP test, CT, vibration and pressure
testing: see page 26.)
A closer look at Weidmüller’s production of stainless steel enclosures
INFO: Weidmüller’s enclosure production process is certied
according to the welding quality standard
DIN EN ISO 3834-3 and DIN EN 15085-2. Thus it is
approved for the welding of railway wagons and railway
components.
