RFQ Checklist for Laser Cladding and LMD Repair

A useful RFQ for laser cladding or LMD repair should define the part, the damaged or target zone, the base material, the service problem, the finish route, the timing and the inspection or documentation needed for release.

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

Answer at the top

One-sentence buyer answer.

A useful RFQ for laser cladding or LMD repair should define the part, the damaged or target zone, the base material, the service problem, the finish route, the timing and the inspection or documentation needed for release.

Use it when

When to use it.

The page is being used to structure an RFQ, supplier check or documentation question.
The main leverage sits in stronger input quality, not in a fast price with thin context.
NDA, drawing release or acceptance logic need early clarity.

Avoid it when

When not to use it.

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

What usually decides the route.

Decision table with decision point, good sign and escalation signal.
Decision point	Good sign	Escalate or avoid
Input quality	Drawings, photos, material and the target function are available.	The request stays generic and data-light.
Comparability	Scope, finishing, inspection and documentation are requested consistently.	Quotes are being compared only on a single price line.
Confidentiality	NDA and file-sharing rules are clear early.	IP protection is only raised late in the process.
Release logic	Acceptance criteria and documentation needs are defined.	PO or release is moving forward without a clear evidence base.

Readable summary:

A useful RFQ includes drawings or photos, material, target function, timing, finish and inspection needs.
Escalate when the request is generic, data-light or compares suppliers only on one price line.
Clarify NDA and file-sharing expectations early.

CS05 - Valve Seat and Wear Ring LMD Coating with Crack-Controlled Co-Based Wear Material

How Exafuse used LMD / laser cladding, ring-specific layer planning and dye inspection to evaluate a Co-based wear-resistant coating route for valve seat and wear ring geometries.

Material and quality

What has to travel with the decision.

Material

Even in procurement, the material route 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 qualification is stronger when deviation handling and release logic are asked explicitly.

Inspection and validation

Checklist before request or release.

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 mode or functional goal, dimensions, finish expectations, timing and the inspection or documentation needed at release.

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.

Buyer questions

Exact buyer questions that usually lead here.

What belongs in a good RFQ at minimum?

Service type, geometry, material, target zone, timing and acceptance logic are the usable core.

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.

What should an RFQ for LMD, repair, or laser cladding include?

At minimum include service type, drawings or CAD, overall dimensions, approximate weight, base material if known, target function of the deposited area, quantity, deadline, and required inspection or documentation.

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 goalScreen 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 release logic.

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.
