Industry Applications


Electric Vehicle Systems Integration


As the EV revolution accelerates, our IP67-rated enclosures (Link 2) safeguard battery management systems from thermal runaway, while proprietary aluminum charge ports (Link 5) withstand 10,000+ mating cycles. Custom mounting brackets (Link 8) enable crash-compliant battery pack integration, meeting UN38.3 transportation safety standards.


Autonomous Driving & ADAS Development

LiDAR sensor housings (Link 3) with MIL-STD-810H vibration resistance ensure millimeter-wave accuracy in off-road conditions. Our EMI-shielded electrophoresis boxes protect sensor fusion ECUs from 5G interference, enabling fail-safe operation in urban canyons. Signal covers (Link 6) maintain optical clarity for camera systems through extreme temperature cycling (-40°C to +85°C).


High-Performance Automotive Tuning

For motorsport and aftermarket sectors, our CNC-machined suspension linkages (Link 1) achieve 40% weight reduction versus steel components while maintaining FIA-grade tensile strength. Turbocharger adapters feature thermal-barrier coatings that reduce under-hood temperatures by 18%, extending turbo lifespan.


Industrial Automation & Robotics

Collaborative robot arms leverage our lightweight servo motor mounts (Link 8) with harmonic dampening properties that reduce positional drift by 0.02°. Conveyor system guides manufactured through precision stamping maintain ±0.05mm alignment tolerance after 2 million cycles.


Energy & Grid Infrastructure

DC fast-charging stations (Link 5) utilize our liquid-cooled enclosures that dissipate 22kW thermal loads without external fans. Solar micro-inverter trays feature UV-stabilized polymers that resist degradation in desert installations. Smart grid monitoring systems deploy our IP55-rated enclosures (Link 2) with integrated heat sinks that maintain 99.999% uptime in substation environments.


Emerging Mobility Ecosystems

From eVTOL battery trays with power-to-weight ratios exceeding 400Wh/kg to hydrogen fuel cell stack plates enabling <0.001% gas permeability - Welden partners with innovators to overcome next-generation engineering challenges.
