Squeeze time is defined as the time between which two events?

• A. Between the application of pressure and the start of current flow
• B. Between the start and end of current flow
• C. Between current flow and pressure release
• D. Between release of pressure and the start of next weld

Answer: (A)

Squeeze time is the interval during resistance welding when the electrodes are pressing the sheets together but no welding current is flowing yet. This period allows intimate contact and helps squeeze out oxides or contaminants, so the electrical contact is stable once the current starts. That’s why the correct description is the time between applying pressure and the onset of current flow. Once current begins, heating occurs at the interfaces; the remaining phases then cover the duration of current flow and the subsequent hold or release steps.
