Estimate Projection Weld Starting Parameters
Estimate conservative starting projection weld parameters for weld nuts, weld studs, weld bolts, and stamped multi-projection parts using fastener type, size, base metal thickness, material, and machine type.
This tool is intended for first-pass setup only. Final production values should always be validated with projection collapse checks, destructive testing, thread quality verification, and actual machine capability.
Total Force = Force per Projection × Number of Projections

Find an IntegratorProjection welding is highly sensitive to projection geometry, fastener design, coating, machine stiffness, force follow-up, electrode face condition, and secondary impedance. These values are conservative starting ranges, not guaranteed production settings.
Weld time shown in cycles assumes a 60 Hz timing reference. Milliseconds are included as a practical cross-reference, especially when comparing AC and MFDC discussions.
What to check next
This tool gives a first-pass setup direction, but real projection welding depends heavily on collapse behavior, force distribution, current balance, part rigidity, coating behavior, and actual machine follow-up. A setup that looks correct on paper can still fail in production if the projections do not collapse evenly.
For real process development, use these values as a starting range only, then confirm with destructive testing, collapse observation, thread quality checks, and confirmation that the machine can actually deliver the required current and force at the part.
