Service / Repair and modification

Repair high-value metal parts before replacement becomes the only option.

This page is for maintenance, plant and procurement teams comparing repair, replacement, downtime, lead time, inspection risk and LMD build-up on an existing component.

Repair fit

Targeted LMD build-up restores local geometry where the base part is still worth saving.

Repair and modification work starts with the damaged zone, base material, duty cycle and acceptance criteria. LMD can restore worn surfaces, replace missing geometry, correct machining errors or add functional zones when the repaired area can be inspected and finished to the required condition.

Use whenDamage is localized, replacement lead time is high, downtime matters and acceptance criteria can be defined.

Strong examplesGear teeth, forging hammers, tooling zones, shafts, undersized surfaces, damaged edges or features that can be rebuilt and machined.

Not ideal whenBase material condition is unknown, damage is systemic, cracking is uncontrolled or the required qualification cannot be met.

Commercial logicRepair should be compared against replacement cost, lead time, downtime, machining, inspection and repeat-failure risk.

Repair route

Repair is an engineering and economics decision.

The route should answer whether the part is technically repairable, commercially worth repairing and inspectable after deposition and finishing.

1Damage reviewPhotos, drawings, dimensions, base material and operating conditions.

2Repair fitCheck localized damage, crack risk, substrate condition and route constraints.

3Build-up planDefine deposition zone, material family, stock allowance and heat-management logic.

4Finish routePlan machining, grinding or surface preparation needed for the functional surface.

5AcceptanceDefine inspection, dimensional checks and documentation before the job starts.

Forging hammer proof

High-impact tooling needs local repair plus validation.

The hammer case study shows targeted LMD build-up, metallurgical bonding logic, 10-20 mm local reinforcement layers and application-specific material strategy. Treat this as a repair candidate pattern, not a universal service-life promise.

Damage zoneHammer faces and tooling surfaces are reviewed by local wear depth, cracks, access and remaining base-part condition.

Repair assessment

Send damage photos, dimensions and base material.

Exafuse can review whether LMD repair or modification is realistic. Final feasibility depends on part condition, inspection needs and finishing route.
