TOP-MFLUX: Magnaflux

Rev: 9/07/2020

Scope: This procedure covers the "special process" of in-house Non-Destructive Testing, sometimes referred to as "Magnaflux Testing".

Procedure:

STEP	WHO	WHEN	INFO TO USE	WHAT TO DO
1	QC Supervisor/QC Inspector	Upon verifying and determining a need for Magnetic Particle Inspection (MPI) testing or per customer's request	Personal observation; Customer Specifications; Traveler	Verify Magnetic Particle Inspection is required, and place a Green Tag labeled "Ready for Magnetic Particle Inspection" inside container; take parts to staging area in Post Forge; notify Post Forge Supervisor or Post Forge Leadman of need for Magnetic Particle Inspection; if Traveler does not have Magnetic Particle Inspection step have QC Supervisor or Post Forge Supervisor add step as required.
2	Post Forge Supervisor or Post Forge Leadman	Upon notification that parts need Magnetic Particle Inspection	Tagged parts; Customer Specifications, Traveler	Add Magnetic Particle Inspection steps to Traveler if required; schedule parts to be inspected.
3	Magnetic Particle Inspector (NDT Level ll)	Upon notification that parts need Magnetic Particle Inspection	The part's identity, use, material, photo, print or actual part; Customer Specifications (if present); earlier Technique Sheet (if present)	Verify that there is a Technique Sheet available; if there is not a Technique Sheet for the job, develop a Technique Sheet based on latest revision of ASTM E 1444, Traveler information or Customer Specifications; submit Technique Sheet to Magnetic Particle Inspector (NDT Level llI); if a Technique Sheet exists continue with the inspection process.
4	Magnetic Particle Inspector (NDT Level llI)	Upon receiving Technique Sheet	Technique Sheet; personal knowledge	Review Technique Sheet for completion; make any needed corrections, sign approval; forward to QA Manager.
5	QA Manager	Upon receiving Technique Sheet	Technique Sheet	Scan Technique Sheet into system.
6	Magnetic Particle Inspector (NDT Level ll)	When inspection of parts is scheduled	Traveler; Technique Sheet; Customer Specifications (if present); Trinity Forge Non Destructive Testing Specification	Conduct examination per Technique Sheet and Trinity ISPEC-MPIWI looking for relevant indications (unless specified differently by the customer's specification or Traveler none of the following will be acceptable: any relevant indication 3/16" or longer, no more than 10 relevant indications in any 6 sq. in. area, four or more relevant indications in a line separated by 1/16" or less edge to edge, no relevant indications in pressure contact sealing surfaces); take any questions to Magnetic Particle Inspector (NDT Level llI); fill out Magnetic Particle Inspection Log; if Traveler requires examination to be certified, work with QA Manager to fill out NDT Certification form then sign it and forward to QA Manager.
7	NDT Level I or Magnetic Particle Inspector (NDT Level ll); QC Supervisor	When parts are inspected and found to need rework	Red Tag for rework of parts; Green MPI Sticker Tag for parts ready to ship	Mark parts to show location of indications that they need rework; place parts in bin marked with Red Tag for rework; place good parts in bin with ready to ship Green MPI Sticker; when all parts are good continue with Production Floor Traveler steps. QC Supervisor will make a sample of rework part; tag it as sample part and place in rework bin for Post Forge Helper to use as sample for conducting rework. NOTE: Be extremely careful not to mix rework parts with good parts.
8	Post Forge Helper	Upon receiving parts from Magnetic Particle Inspection labeled with rework Red Tag	Sample rework part labeled by QC Supervisor, bin with parts marked with rework Red Tag	Rework parts in accordance with sample part; place rework parts in new parts bin labeled with ready for Magnetic Particle Inspection; continue with process until all indications are completely reworked; if deemed scrap fill out Scrap Report and enter in M2M.
9	QA Manager	Upon receipt of completed NDT Certification	NDT Certification	Verify that the certification has been completed per this TOP; e-mail Post Forge Supervisor that the NDT Certification has been reviewed and approved; issue NDT Certification to customer per TOP-ORDER and file NDT Certification traceability copy on server.

NOTE: The calibration and maintenance procedure for MPI equipment can be found in ISPEC-MPICM. The qualification and certification of NDT personnel can be found in ISPEC-NDTTR .
