Figure 6-8 Weld Segment Terminated by a Bad Part Limit

Weld Termination Due to Secondary Control

Secondary controls are additional controls that allow the weld to be con-

trolled by more than one process parameter. In this example, the weld por-

tion of the cycle ends when either the primary control parameter (in this

case, Weld by Time for 50 ms) or the secondary control parameter (Weld

Energy for 20.0 joules) is reached. In either case, the cycle proceeds to

the hold portion of the cycle provided that no process characteristics fall

outside of the bad limits. Figure 6-7 shows the results using Weld Energy

as a secondary control.

Figure 6-7 Weld Segment Terminated by a Secondary Control

Weld Termination Due to a Bad Limit

As with all bad part limits, falling outside of a limit results in an immediate

termination of the process. Figure 6-8 illustrates the results when a bad part

limit was exceeded for Weld Energy. The two “greater than” arrows (>>)

preceding the Weld Energy measurement indicates that a bad part upper

limit was exceeded. These arrows, known as limit indicators, are always

displayed in the Cycle Data.
