Do the following to use Pie Mode:
1. Set up the BoreWelder as described in Section 3 and in this section.
2. Set the Auto Skip cams for the scenario of skipping the worn section (see
Section 4.6 on page 53).
3. While not welding, hold down the
FUNCTION
key and press
WELD
once (to
cycle from Auto Skip to Pie Mode).
4. Resume welding as for normal borewelding.
The BoreWelder will now weld back and forth inside the worn area, stopping the
weld process, stepping, then beginning weld again in the opposite direction at each
end point. The weld parameters are controlled exactly the same as for normal bore-
welding.
If multiple passes are needed to ensure complete correction of the worn bore, CLI-
MAX recommends starting with a small pie section for the first pass, widening the
pie for the second pass, and so on. In this way, the stops and starts are hidden
underneath the subsequent beads, simplifying the machining process.
4.7.2
Carriage return
Carriage Return is used to weld up a worn area of a bore in the horizontal axis,
when the worn section occurs on the uphill or downhill side of the bore.
The following procedure assumes you have just powered up the control and are in
the Auto Skip mode.
Do the following to use Carriage Return:
1. Set up the BoreWelder as described in Section 3 and in this section.
2. Set the Auto Skip cams for the scenario of skipping the worn section.
3. While not welding, hold down the
FUNCTION
key and press
WELD
twice (to
cycle from Auto Skip to Carriage Return).
4. Set the rotation direction to the preferred weld direction for your applica-
tion by holding down the
FUNCTION
key and pressing the
ROTATE
button to
toggle the rotation direction.
5. Resume welding as for normal borewelding.
The BoreWelder welds in the rotation direction inside the worn area, until it
reaches the end of the set cam limit. It then stops welding and reverses rotation at
full speed to the original starting point while stepping. The weld and rotation begin
again. All parameters are set as for normal borewelding.
