Build A Process FMEA For A Vent Defect

A laser-weld station found three shallow vent-tab welds in one shift. The team needs a process FMEA entry before deciding whether current controls are enough. FMEA path: function, failure mode, effect, cause, controls, action. The weak entry says "weld issue - inspect more." It hides the function, effect, and detection weakness, so the action may become extra sorting instead of better control. Before Weld issue found on vent tab. Operator to inspect and adjust. After Function: maintain designed vent opening behavior. Failure mode: vent-tab weld penetration below minimum. Effect: delayed or inconsistent venting under abuse pressure, invalidating safety margin. Cause:…
