welddata Weld data
Description
Welddata is used to control the weld during the weld phase, that is, from when the arc
is established until the weld is completed.
Other phases, such as the start and end phases, are controlled using seamdata.
Weld data describes data that is often changed along a seam. Weld data used in a given
instruction along a path affects the weld until the specified position is reached. Using
instructions with different weld data, it is thus possible to achieve optimum control of
the welding equipment along an entire seam.
Weld data affects the weld when fusion has been established (after heating) at the start
of a process.
In the case of a flying start, the arc is not ignited until the destination position of the
arc welding instruction with the \On argument is reached, which means that weld data
does not have any effect on the weld in this instruction.
If one arc welding instruction is exchanged for another during a weld, new weld data
will occur in the middle of the corner path.
Note. Some of the components of weld data depend on the configuration of the robot.
If a given feature is omitted, the corresponding component is left out of the weld 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.)
