In order to be sure that production welds are good,
it must be verified that the parameters of each weld
match the parameters of a known good weld. A
master is made from a weld or welds which are
proven to be good through destructive testing. The
master is the average of all parameters for these
welds. The general procedure for creating a master
is as follows:
Note:
Individual applications may have different
procedures for creating masters. If this is the case,
you should create masters according to the
procedure specific to your application.
1. Press the New button. Using the same weld schedule and bin select, make several of the same type
of weld, marking the weld number on each workpiece.
2. Press the Done button. Destructively test all of the welds made during mastering.
3. Using the Edit Master option, delete any welds from the master that failed destructive testing.
4. Update the master. New welds will now be compared to the known good welds in the master.
Note:
Using different bin selects, multiple masters can be made at the same time. For more
information about, refer to Chapter 9, FAQ.
The Mastering options are described below. Some option buttons will be disabled (text shown fuzzy)
during the mastering process, or if no masters exist for the selected POD / ID.

New/Done
This option button starts and ends the mastering
process. Once the
New button is pressed, the
screen reads Initializing master memory…
The button text then changes to Done and the
screen reads Creating new master: Ready to
accept welds… Once you have finished adding
welds to the master, use the Done button to end
the mastering process.
When the
Done button is pressed, the software
calculates a master from the average of the
welds that were included in the master. The
Master ID (name) defaults to be the current
date and time. When the master is complete, by
default it will be broken up into three segments:
Segment 0 – Pre Weld (before current starts)
Segment 1 – Weld (portion of weld with current)
Segment 2 – Post Weld (after current stops)
