RFQ Checklist for Laser Cladding and LMD Repair

A useful RFQ for laser cladding or LMD repair defines the part, target zone, base material, operating problem, final surface, timing and acceptance requirements.

RFQ and procurement package visual for LMD repair and laser cladding requests

In brief

The short answer.

A useful RFQ for laser cladding or LMD repair defines the part, target zone, base material, operating problem, final surface, timing and acceptance requirements.

A good fit when

When it is a good fit.

Use this page to prepare an RFQ, supplier review or documentation question.
Better input data usually matters more than a fast price based on incomplete information.
Clarify NDA terms, drawing access and acceptance requirements early.

Consider another process when

When another process may be better.

A quick price is being requested with no technical input.
Several suppliers are being compared while scope and acceptance remain undefined.
Confidentiality is only raised after sensitive files have already been shared.

Decision table

Key criteria for the process choice.

Decision table with decision point, good sign and escalation signal.
Decision point	Good sign	Escalate or avoid
Technical input	Drawings, photos, material and the target requirement are available.	The request remains too general for a sound review.
Comparability	Scope, finishing, inspection and documentation are requested consistently.	Quotes are compared on price alone.
Confidentiality	NDA and file-sharing rules are agreed early.	IP protection is raised only after sensitive files are shared.
Acceptance	Acceptance criteria and documentation needs are defined.	An order moves forward without a clear basis for acceptance.

In summary:

A useful RFQ defines the part, material, function, timing, finishing and inspection needs.
Clarify scope and acceptance criteria before comparing prices.
Agree confidentiality and secure file-transfer requirements early.

Material and quality

What needs to be reviewed alongside the process.

Material

Even in procurement, material selection should stay tied to function and substrate.
If substitution is possible, it needs a clear approval rule.

Quality

A good RFQ names inspection, documentation and the delivery condition.
Supplier reviews are stronger when deviation handling and acceptance are discussed explicitly.

Inspection and acceptance

Checklist for the enquiry and acceptance plan.

Service type and target of the job
Drawing, CAD or photos
Material or substrate assumption
Inspection and documentation package
NDA, timing and delivery terms

Many RFQs fail because they describe only the part and not the actual technical decision. Laser cladding and LMD repair both need more structure than a generic "please quote."

The short answer

For repair and cladding RFQs, the useful minimum is: part identity, target zone, base material if known, failure mechanism or functional goal, dimensions, required final surface, timing and the inspection or documentation needed for acceptance.

Core checklist

Part name and service type: repair, modification or cladding.
Drawing, CAD or clear photos.
Damage zone or target surface description.
Base material or best available substrate assumption.
Function of the rebuilt or coated area.
Required finish, machining or grinding.
Quantity and deadline.
Inspection expectations and documentation needs.
NDA or confidentiality needs if relevant.

Repair-specific additions

Add the failure description, downtime pressure, replacement lead time where relevant and any evidence about the current condition of the substrate.

Cladding-specific additions

Add the service medium, wear or corrosion mechanism, operating temperature, target layer function and whether hard coatings, preheating or post-heat treatment are allowed.

Why these details matter

Procurement and engineering can compare offers only when the requested scope, finishing and acceptance requirements are clear. Missing information should be identified before a price is treated as comparable.

Next step

Prepare the enquiry with the RFQ builder, then use the contact page, procurement guide, repair cost comparison or material-selection guide as needed.

Common project questions

Questions that often arise in similar projects.

What belongs in a good RFQ at minimum?

Service type, geometry, material, target zone, timing and acceptance criteria provide the technical basis.

How should quotes actually be compared?

Not only on a deposition price, but on scope, finishing, inspection, documentation and the assumptions underneath them.

When should NDA be raised?

As early as possible, ideally before sensitive drawings or internal information are shared.

Example RFQ packages

Four typical request packages, clearly marked as examples.

These examples are not customer cases and not quotations. They show which information makes an initial technical review faster and more reliable.

Example

Example package: LMD repair

Part goalRestore local geometry on a valuable component without defaulting too early to replacement.

Known dataPhotos of the damage zone, approximate dimensions, function, downtime pressure and any drawing already available.

Missing dataConfirm base material, check cracking, define target geometry and agree acceptance criteria.

Useful files / photosOverview photos, detail photos, drawing or CAD, material information and a marked damage zone.

Inspection expectationDimensional review, surface review and project-dependent crack or cross-section inspection.

What Exafuse can review firstWhether a local LMD route is technically more useful than replacement, welding or remanufacture.

What remains openMaterial compatibility, access, finishing, remaining service logic and release stay project-specific.

Example

Example package: laser cladding

Part goalSpecify a metallurgically bonded protective layer for a wear- or corrosion-critical zone.

Known dataSubstrate, failure mode, medium, temperature, contact type and affected surface.

Missing dataTarget layer, material family, preheating constraints, finishing route and inspection scope.

Useful files / photosPart photos, wear images, drawing, coating zone, service environment and preferred final surface.

Inspection expectationGeometry, layer appearance, crack review or metallographic context depending on part risk.

What Exafuse can review firstWhich material family and thermal route are plausible for the failure mechanism.

What remains openExact alloy, process window, post-processing and acceptance should only be fixed after technical review.

Example

Example package: large LMD build

Part goalAssess a large metal component or structural node for an LMD / DED-LB/M route.

Known dataCAD, envelope, approximate mass, function, interfaces and intended material.

Missing dataManufacturing adaptation, deposition strategy, finishing allowance, fixturing logic and validation plan.

Useful files / photos3D model, drawings, interfaces, load or function description and critical surfaces.

Inspection expectationDimensional accuracy, surfaces, post-processing and project-specific inspection or acceptance criteria.

What Exafuse can review firstWhether LMD, SLM, hybrid manufacturing or a conventional route is more robust.

What remains openNot every geometry is additive-ready; design adaptation and the inspection path must be planned together.

Example

Example package: SLM / LPBF compact part

Part goalEvaluate a compact metal part with fine detail, internal channels or powder-bed-native geometry.

Known dataCAD, material request, part size, quantity, functional surfaces and timing.

Missing dataBuild orientation, supports, heat treatment, post-processing and inspection requirements.

Useful files / photosSTEP file, drawing, critical internal geometry, tolerances and desired surfaces.

Inspection expectationDimensional review, surface review and, depending on application, density, CT or other inspection logic.

What Exafuse can review firstWhether SLM / LPBF, LMD or a hybrid route solves the task more cleanly.

What remains openCompact detail can favor SLM, but material, supports, finish and release still decide the route.
