Laser Micro Welding Services for Ultra-Fine, High-Accuracy Components

Micro laser welding is an advanced joining process that uses highly focused laser energy to create precise welds on miniature and delicate components. The process delivers controlled heat input at the microscopic level, typically with spot sizes from 0.2 to 2mm and penetration depths as fine as 0.1mm. This enables welding of ultra-thin materials, small assemblies, and sensitive parts where conventional welding would cause distortion or damage. The technology is ideal for medical devices, aerospace instrumentation, electronics housings, and precision mechanical assemblies requiring exceptional dimensional control.

Our micro laser welding capabilities extend down to 0.1mm minimum deposit size with spot sizes as small as 0.2mm. We routinely weld components with wall thicknesses under 0.5mm, wire diameters down to 0.2mm, and assemblies weighing less than 1 gram. The microscope-assisted positioning system enables precise placement on features invisible to the naked eye, making us capable of handling even the most miniature precision assemblies.

We work with a broad range of materials including stainless steel (300 and 400 series), titanium and titanium alloys, aluminum, copper, beryllium copper, nickel alloys, tool steels, and various specialty metals. Material compatibility is evaluated during the application review phase, and we can perform weld trials to validate process parameters for specific material combinations or grades.

Laser micro welding minimizes distortion through highly localized energy delivery. The focused laser beam concentrates heat precisely at the weld zone while surrounding areas remain relatively cool. With pulse widths adjustable from 0.3 to 20 milliseconds and controlled energy density, we create minimal heat-affected zones. This thermal precision is critical for thin sections, delicate geometries, and components with tight dimensional tolerances where even minor warping is unacceptable.

Yes, we specialize in collaborative R&D support including prototype welding, process development, and design-for-manufacturability validation. Our approach includes iterative welding trials, fixture development, parameter optimization, and documentation—providing the technical partnership needed during product development phases. We support quantities from single prototypes to pilot production runs before scaling to full manufacturing volumes.

Every micro welding job follows documented welding procedures with microscope-assisted inspection. Our AWS-certified welders execute validated parameters, and we maintain comprehensive process records for traceability. Post-weld inspection verifies dimensional accuracy, weld integrity, and absence of defects. Our consistently low defect rate of less than 1% reflects strict quality discipline across prototype and production work.

Yes, we provide precision laser micro welding for medical device components including surgical instruments, implantable devices, catheter assemblies, diagnostic equipment, and specialty medical tooling. Our controlled processes, clean welding environment, and documentation standards support the stringent requirements of medical manufacturing. We work with biocompatible materials and can support design validation testing requirements.

Turnaround time depends on component complexity, volume, and whether process development is required. For established processes with defined parameters, small batches typically complete within 5-10 business days. New applications requiring process development and weld trials may need 2-4 weeks for optimization and validation. Urgent or production-critical jobs can be expedited with prior coordination. We provide delivery timelines upfront after technical evaluation.
