The problem with inspecting this type of cold weld is that the outer bead of the joint is the same
as that of a good joint. In the sample above, the top bead represents the outer look of the
weld. It can be seen very clearly that both welds look the same according to the bead formation.
Since the occurrence of a cold weld is difficult to inspect and find, the UF2000 equipment has
been designed to measure the joining force during the fusion process. Therefore, if an operator joins the
material with too high or too low a force or brings the material together at too fast or slow a rate, the unit
will identify this and produce an error message on the print out label.

Downloading Data / Data Transfer
The UF2000 Equipment is equipped with a memory to store information on each weld. The
tool has a capacity of approximately 1000 to 1100 welds. The data on each weld can be
transferred to a PC computer utilizing the Wicon software that is included in each unit. The data transferred
from each weld provides an inspector with more information about the weld than
what appears on the
printout label. Below is an example of the data:

The data transfer feature allows the inspector or installer to have back-up documentation on the
welds conducted on the tool. By reviewing the welds
,
it can also be identified if weld counts
were reset during the installation, since the tool will record all welds.
The procedure for the Wicon software installation and Data transfer usage is found in the UF2000
binder in the last section. Below is brief description of the process which can be utilized as a
reminder. For further details refer to the binder.
