seamdata Seam data
Description
Seamdata is used to control the start and end of the weld. Seamdata is also used if the
process is restarted after a welding operation has been interrupted.
The actual weld phase is controlled using welddata.
Seam data describes data, the values of which, as a rule, can be maintained unaltered
when welding a complete run and often also when welding several seams. Seam data
is used when preparing for the welding operation, when igniting the arc, when heating
after the ignition and also when ending the weld.
Seam data is included in all arc welding instructions to facilitate controlled end and
start phases irrespective of where the interrupts or restarts occur.
Note. Some of the components of seam data depend on the configuration of the robot.
If a given feature is omitted, the corresponding component is left out of the seam data.
The conditions that must be met for components to exist are described in the system
parameters.
All voltages can be expressed in two ways (determined by the welding equipment):
- As absolute values (only positive values are used in this case).
- As corrections of values set in the process equipment (both positive and negative
values are used in this case).
Feeding the weld electrode in this section refers to MIG/MAG welding. In the case of
TIG welding:
- A cold wire is supplied to the wire feed.
- The necessary welding current reference value can be connected to any of the
three analog outputs that are not used. (The Welding voltage reference is not
used.)
