  • Match filler to the required material and surface properties.
  • Accept the result after the full finishing route.

Plan the repair around the tool’s function

A restored contour is only part of a successful tool repair. The base material, weld region and finishing route must suit the required dimensions, surface and operating duty. Begin with a documented assessment of the damage and a representative application trial.

Worn edges and local surfaces

Identify missing material, remaining geometry and the final contour. Include the machining allowance and surface condition that the repair must retain.

Feature changes or corrections

Define the drawing revision, material condition and the region to restore or alter. Review access, filler compatibility and any post-treatment needed.

Cracks and previous repairs

Assess the cause and full extent with the tool owner and repair specialist. A surface pass does not establish that a crack or underlying problem has been removed.

Follow the complete restoration

  1. Assess the tool

    Record material, condition, damage and required duty.

  2. Qualify the repair

    Review preparation, filler, access and the offered process.

  3. Restore and finish

    Include the specified machining and surface treatment.

  4. Inspect and release

    Accept dimensions, material condition and function before return to service.

Specify the repair machine and the application together

Request a model-specific technical sheet and supply list. The public STR catalogue uses a broad power description and a fiber-source menu label without a matching detailed model specification; confirm the actual source and process rather than inferring them from the image.

ItemDefinition required in the offer
Model and laser processModel/revision, source architecture, output definition and operating mode; applicable pulse or other control ranges and duty conditions.
Head and accessHead/optics, usable focus/working distances, reach to the actual feature, shielding and any movement or positioning options.
Workpiece supportTool size/mass, table/travel and holding limits, positioning method, fixture interfaces and service clearances.
ObservationMicroscope specification, alignment, illumination, focus and any camera/display or protected viewing option.
Material and fillerQualified base grades/conditions, compatible filler, preparation, thermal-treatment responsibilities and sample acceptance.
Cooling and installationCooling package, electrical/gas/extraction requirements, protective arrangement and site responsibilities.
Supply and supportIncluded controls/accessories, wear parts, training, maintenance, service, delivery and commercial scope.

The catalogue mentions water cooling and microscope observation. Confirm them for the ordered build. No numeric power, repair depth, table capacity, axis count, positioning accuracy or material-hardness capability is established here.

Review the stage that decides whether the repair is complete

Four stages to agree before the trial

Select a stage to see the information needed for the application review. This is a procurement and acceptance guide, not a repair procedure or a verified machine sequence.

Assess the damage and tool condition

Identify the base grade, heat-treatment and hardness condition, damage extent and previous repairs or coatings.

Agree the required result
The restored feature, drawing revision, operating duty and the basis for deciding that repair is appropriate.
Evidence to request
Tool records, photographs and dimensions, plus the repair specialist’s assessment and any required examination.

Separate a shallow surface correction, an edge rebuild and a crack repair in the application. The amount of deposited metal is not itself an acceptance criterion, and a finished-looking patch is not evidence of restored service life.

Match the base condition and filler to the tool application

InputWhy it belongs in the application review
Base grade and conditionProvide the exact tool material, delivered/heat-treated condition, known hardness and service history. Similar trade names do not establish equivalent repair behavior.
Filler selectionReview composition, fusion and required properties with the base-material or repair specialist. Include hardness, toughness and finishing behavior relevant to the tool.
Coatings and previous repairIdentify nitriding, plating, surface treatments and old weld/filler regions. Agree preparation and any treatment before or after the repair.
Required surface propertiesSpecify polishing, texture/etching, corrosion or wear requirements. A hardness target alone does not establish the complete functional surface.
Heat-treatment routeConfirm any required preparation or post-weld treatment from the grade-specific repair plan. The laser label is not a universal exemption from thermal treatment.

Material background: Uddeholm’s tool-steel welding guidance connects deposit properties to the base steel and filler, and identifies different requirements for hot work, cold work and plastic moulding. It supports application-specific selection; it is not a test or material qualification of the STR machine.

Define the restoration geometry and finishing allowance

Local wear or an edge

Show the remaining section, missing volume and final profile. Agree the dimensions and surface to retain after machining rather than assessing only the as-deposited shape.

Cavity or cosmetic surface

Provide required polish, texture or appearance and any matching adjacent surface. Trial the final finishing process on representative repaired material.

Crack or repeated failure

Document location, extent and relevant service history. The cause and sound repair boundary require assessment; do not treat a visible surface closure as proof of a complete repair.

Feature change

Supply the before/after drawings and the material condition at the time of repair. Confirm which operations and inspection are included in the quoted route.

Prove access with the actual tool and fixture

Microscope and head assembly enlarged from the original STR mould repair welding catalogue image

Check the feature, not only the outside tool size

Review the actual repair location with the offered head, focus, viewing and filler/shielding arrangement. Deep features, nearby walls or tool holders may change what can be accessed.

The catalogue photograph shows a head and microscope above a table. It does not establish an articulating arm, motorized axes, CNC operation or access to every cavity.

Size and mass

Provide complete-tool and insert dimensions, mass and lifting/positioning needs. Confirm table/support limits and usable access for the ordered build.

Orientation and working clearance

Use the real fixture or an agreed equivalent to demonstrate focus, viewing and approach. Include any repositioning and its effect on datums.

Fine filler and shielding access

Review access for filler and shielding if required by the qualified process. A head that can see the feature may not establish the complete repair arrangement.

Observation and protection

Obtain the actual microscope/window protection and machine protective-function documentation. Confirm illumination and working ergonomics without substituting a visual component for a verified protection rating.

Judge the repair after the specified post-processing

Plan the work following welding before agreeing the trial. The final repair may require machining, grinding, polishing, texture restoration, coating or grade-specific thermal treatment. Confirm the appropriate route with the tool owner, material supplier and repair specialist.

Dimensional restoration

Measure the final geometry against the agreed drawing and datums after the required operations. Include any change to adjacent surfaces or fit.

Machining behavior

Trial the selected cutter, grinding or other finishing process as appropriate. Identify hard spots, defects or differences that prevent the required finish.

Polish and texture

Assess the repaired region and its boundary after representative polishing or texturing. A smooth as-welded patch does not establish a matched cavity finish.

Material and functional result

Agree required hardness/examination and functional acceptance for the specific tool. Avoid a universal strength, hardness or added-service-life claim.

Accept the repaired feature and document its release

Use representative material with the relevant grade and condition, an agreed repair plan and measurable acceptance criteria. Trace the machine/source/head, filler, preparation, setup and finishing used in the trial.

CheckEvidence to keep
Incoming conditionTool/insert ID, base grade, heat-treatment/hardness records, coatings, previous repair and documented damage.
Process and accessOffered configuration, fixture, repair location, preparation/filler and any thermal-treatment responsibilities.
Repair integrityAgreed examination of fusion, defects and repaired area, appropriate to the feature and intended duty.
Final geometryDimensions, restored contour, fit and any adjacent changes after the specified finishing.

Release recordRepair scope, inspection results, any restrictions and the tool owner’s return-to-service decision.
Complete workloadAssessment, preparation, setup, deposition, finishing, inspection and handling measured separately.

Request a finished representative repair

A machine image or deposition demonstration is not a repair-quality record. Include the difficult access and actual material condition, and retain inspection after the required machining or surface finishing.

Laser welding is one proposed repair tool. The right choice depends on a sound repair assessment and the accepted finished tool; a lower heat-input claim alone does not establish no distortion, no cracking or restored service life.

Include tool handling, utilities and the protective arrangement

Toolroom layout

Obtain the ordered footprint, workpiece handling route, lifting/fixture interfaces and maintenance access. Confirm whether the tool can be brought to the machine in the intended condition.

Cooling and services

Confirm electrical input, cooling/environment, gas/shielding and extraction requirements for the exact build and materials.

Laser area and protection

Review the complete protective arrangement and installation with competent personnel. Confirm rated viewing protection, access controls and training; an open table or microscope does not certify the work area.

Repair traceability

Keep tool IDs, material/filler records, approved process and inspection connected through outsourcing, finishing and return to production.

Maintain the delivered head, motion and service package

Optics and viewing

Follow the actual manual for inspection, cleaning and replacement. Use the specified protective optics and service references; do not improvise viewing filters.

Positioning and fixtures

Retain approved setup records and inspect fitted tables, guides, holders and contacts when access or dimensional results change. Do not infer a motion-service schedule from the picture.

Source, cooling and shielding

Use the source- and cooling-specific maintenance plan supplied for the model. Identify consumables and service limits from the delivered BOM.

Training and support

Include setup, material/process records, approved operation/recovery and service responsibility. Confirm spare parts, documentation and backups for fitted controls.

Compare the delivered system and the cost of an accepted repair

The dated offer should identify the actual laser/source/control, head, observation, workpiece positioning/support, cooling, shielding/accessories, protective equipment/interfaces and training. Record the representative repair and final finishing/inspection scope, with exclusions.

Agree packing, transport, commissioning, manuals, spare parts, service contacts, warranty conditions and delivery schedule. Compare assessment, preparation, filler, welding, finishing, testing and rejected/reworked repairs over the same task. No repair depth, hardness recovery, service-life extension or payback is guaranteed by the catalogue label.

Questions before selecting a mould repair welder

Which laser source is used in the STR mould repair machine?

The public menu labels the category as fiber welding, while the broad catalogue card does not provide a matching detailed model/source specification. Request the exact source, operating mode and technical sheet for the offered build; the image is not sufficient to determine them.

Can it repair every tool steel or hardness condition?

No universal material range is established here. Provide the exact grade, heat-treatment/hardness condition, service history and repair task for an application-specific assessment and trial.

How should filler be selected?

Match it to the base material, condition and required final properties with the material/repair specialist. Include fusion, hardness, toughness and machining/polish/texture needs as relevant.

Does laser repair eliminate preheating or post-treatment?

Do not assume that from the laser label. Use the material-specific qualified repair plan to define any preparation or thermal treatment required before or after welding.

Can a visible crack simply be covered with deposited metal?

A crack requires assessment of cause, extent and a sound repair boundary. A closed-looking surface does not establish removal of the problem or an accepted repair.

Does the microscope and table mean CNC operation is included?

No. Confirm viewing, movement, travel, positioning and any automation separately in the actual scope. Appearance does not establish axis count or control functions.

Will the repaired surface polish or texture like the original?

Establish the required finish and test representative repaired material after the intended post-processing. The result depends on base/filler/process and cannot be proved by an as-deposited image.

What should I send for a quotation?

Send the base grade, heat-treatment/hardness and prior repair records, tool dimensions/mass, damage photos/dimensions, final drawing and tolerance, access, filler if known, finishing/inspection requirements and destination.
