Preventive Maintenance

Circumferential Weld Parameter Audit

The positioner can be healthy and still be wrong. The failure that matters is a weld procedure revision that does not match the article on the headstock. The machine will run either revision.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Confirm the loaded weld procedure is the released revision for this article
  2. Inspect torch, gas delivery, positioner backlash and ground return
  3. Run a coupon on scrap only if the released procedure calls for one
  4. Record the weld-cycle counter
  5. Stop and write a nonconformance if the loaded revision does not match the article

Why This PM Exists

The positioner can be healthy and still be wrong. The failure that matters is a weld procedure revision that does not match the article on the headstock. The machine will run either revision.

What Skipping It Looks Like

Maintenance clears the fault, production reloads the usual programme, and the traveler still says the article is to the released revision. Those two facts disagree, and only one is written down.

Setting the interval

Weekly, and on weld cycles. A revision mismatch is a nonconformance, not a parameter tweak from the maintenance screen.
