Multi-layer Welding Function

Multi-layer Welding Function
The DX100 is used to weld a workpiece with multiple layers which,
otherwise, cannot be satisfactorily welded with a single layer. The first
layer is welded while the COMARC instruction executes the arc sensing
for correcting the path. At the same time, the path is stored and jobs for
the 2nd and following layers are created automatically based on the
stored path by the memory and playback function.
Since the workpieces subjected to the multi-layer welding are generally
thick and have problems such as "variations in welding accuracy",
"distortion during welding", and "positioning errors due to setting error",
simply reproducing the taught path is not enough to attain high-quality
welding. For the solution of these problems, the search function and the
arc sensing function are used.

Features

The main features of multi-layer welding function are listed below.
Contents
The taught position data on the 1st
layer are registered in point
variables. These point variables
can be used for weldings on the
2nd and following layers.
Stores the corrected path of the
first layer by the arc sensor and
reproduces the stored path on the
second and the following layers.
Four shift patterns are available. At
the execution of the instruction, the
amount of the deviation from the
taught position is automatically
calculated and the following steps
are shifted accordingly.
During playback operation, the
welding conditions can be adjusted
and changed.
After the search and shift
operations, the taught position can
be modified during the shift
operation in teach mode.

Features
By using the point variables where
the taught position data on the first
layer are registered, the time
required for the teaching for the
second and the following layers
can be reduced.
Reproducing the corrected path on
the first layer for the second and
the following layers realizes the
high-quality welding.
For reproducing the corrected path
for the second and the following
layers, either the same direction as
the welding on first layer or the
reversed direction can be selected.
One instruction executes search
and shift functions, which simplifies
the operation.
Specifying the shift type such as
shift in parallel or shift in rotation
makes the correction of the
workpiece positioning error easy.
Overriding the welding conditions
such as arc sensing, weaving
amplitude, realizes easy
adjustment of the welding
conditions.
Since it is not necessary to change
the target position on the master
workpiece, the modification of the
taught position is easy.
