Welding Points on Diagonals:
Welds that travel all the way around the diagonal are
not necessary up to certain types of applications such as heavy duty and
extra heavy duty. Welds that do travel all the way around are usually
found on truss that measures 18” wide or larger.
An opening of 3-5 mm wide is necessary in order to allow
the inert gas to completely escape the filler tube. This actually creates
a stronger, more precise weld for light/medium duty truss such as our
F32, F33 and F34 series.
What is a Deflection?
Deflection is the maximum allowable amount of bowing or
bending. It is usually measured in inches or millimeters. This determines
just how much bending is ‘OK’ and how much is ‘NOT OK’.

What is TÜV
TÜV is a 3rd party certification body and a Nationally
Recognized Testing Laboratory (NRTL), just like OSHA. TÜV’s
range of services includes consultancy, inspections, tests and expert
opinions as well as certification and training. All the while, maintaining
objectives such as reliability, safety and quality, environmental protection
and cost effectiveness.
Established over 130 years ago in Bavaria, TÜV is
a globally active company, represented internationally by more than 130
locations and is headquartered in Munich, Germany. On a global scale,
over 24,000 product and 12,000 quality management system certifications
have been issued by TÜV.
Management Service division: TÜV is an accredited
Management Systems Registrar in the US, Europe and Asia, providing ISO
9000, ISO 14001, QS-9000, TE Supplement, AS9100, VDA 6.1, EN 46000, ISO
13485/13488 and ISO/TS 16949 certification services. http://www.tuvam.com
Certificates: A certificate of welding is available confirming
such standards set forth by TÜV are carefully observed and maintained
throughout the welding processes.
Welding:
What type of welding process is used on the truss? Global
truss is made using the TIG welding process. TIG stands for Tungsten Inert
Gas. It is also called GTAW (Gas Tungsten Arc Welding). The arc is started
with a tungsten electrode shielded by inert gas. A filler rod is fed into
the weld puddle separately. This process is more time consuming than other
types, but it produces a more precise weld, can be used at lower amperages
for thinner metal and can be used on exotic metals.
What is Inert Gas?
Inert gas (a.k.a. noble gas) is any of a group of rare
gases that include helium, neon, argon, krypton, xenon, and sometimes
radon and that exhibit great stability and extremely low reaction rates.
They are used to shield the electric arc from outside contaminants and
gases that may react with the weld.
What is UDL and CPL?
UDL stands for Uniformly Distributed Load. This describes
how the weight or load is distributed on the truss and how the values
found on the loading and deflection table are generated.
CPL stands for Center Point Load. Again, describing the
distribution of weight on the truss.Other types of loads are TPL (Third
Point Load) and QPL (Quarter Point Load).
