- Laser Welding
IPG laser welding for precision assemblies, minimal distortion, and clean, GMP-compliant finishes.
- Service Overview
Laser welding at Kurveline uses the IPG Laser Welding Machine — which produces a fundamentally different result from conventional MIG or TIG welding. The concentrated laser beam delivers heat to a narrow zone, producing a tight weld bead with minimal heat-affected zone and significantly less thermal distortion. For assemblies where post-weld dimensional accuracy is critical, or where GMP crevice-free finish is required, laser welding is the engineering answer.
Kurveline laser-welds precision sheet metal assemblies — medical device chassis, cleanroom furniture joints, stainless steel enclosures, and structural frames requiring tight post-weld tolerance.
- ±0.5 mm post-weld tolerance demonstrated on a 31-component medical device chassis (EM200 — CII-AMTZ MedTech Quality Champion Nominated 2024)
- In-house welding fixtures designed and manufactured for every tolerance-critical assembly
- Receiver gauge check at every unit — not just first-article inspection
- GMP crevice-free weld finish available — appropriate for pharma and food contact surfaces
- IPG laser welding produces high-strength, low-distortion joints suitable for structural assemblies

Customization
Weld configuration, material grade, post-weld dimensional tolerance, surface finish Ra value for GMP applications, crevice-free weld requirement on contact joints, fixture requirement, and production quantity can all be specified. GD&T drawings preferred for tolerance-critical assemblies.
Our Process
Brief / GD&T Drawing
Assembly requirements, materials, and GD&T tolerances confirmed with the client.
Fixture Design & Manufacture
Welding fixtures and receiver gauges designed and made in-house for each assembly.
Production Welding
Components laser welded in the fixture with parameters set for each material.
Receiver Gauge Check
Welded assemblies checked on the receiver gauge for post-weld tolerance.
Surface Finish
Product-contact joints ground and polished to a crevice-free finish.
QC Documentation & Dispatch
Inspection records compiled and assemblies released for dispatch.
Quality & Engineering
Every welded assembly is verified against in-house receiver gauges at each production unit. Dimensional records and weld inspection are documented. Material traceability certificates are available for SS grades. CII-AMTZ MedTech Quality Champion Award Nominated 2024 — EM200 Medical Device Chassis.
