Section IV. Developing Weld Schedules
This section is a guide to be used in establishing the parameters required to make a successful weld. Careful
development of a weld schedule will aid in achieving a repeatable reliable process.
Resistance Welding Parameters
The three basic welding parameters are Heat, Time, and Pressure which are controlled by:
Parameter Controlling Factors
Heat
Primary Tap Setting of Welding Transformer
Secondary Tap Connections of Welding Transformer
%CURRENT selected on PM6
Time WELD CYCLES selected on PM6
Pressure
Electrode Firing Force set on Welding Head
Surface Area of Electrode Faces
The interaction between the three basic welding parameters should be considered when developing a Weld
Schedule.
Weld Schedule Development
Developing a weld schedule is a methodical procedure consisting of making sample welds and evaluating the results.
You should make the first weld at low energy settings. Then, you make adjustments to each of the parameters
one
at a time until a successful weld is made.
