Figure 2a shows a case where the weigh module
itself acts as a fixture for holding the welding plates
in position. Note that the welding plates are slightly
bigger than the top resp. the bottom plates. This
makes it easy to hold a piece of sheet metal against
the welding plate to protect the weigh module from
weld splashes.
When welding, make sure that the ground cable of
the welding machine is connected to the same side
at which the welding is done, so that no current
flows through the load cell. Load cell cable should
preferably not be connected in the summing box
during welding.
Figure 2b illustrates a case where the load carrier
has been prepared with mounting holes from
factory. The weigh module holds the welding plate
in position against the foundation, ready for welding.
This method opens the possibility of pre-installing
the modules to the load carrier in the factory and
deliver, ready for the final welding operation on site.
Figure 3 is similar to 2b, but in this case, the base
plate of the weigh module is welded directly to the
foundation plate without any welding plate in
between.
