Project Summary

A precision metal-stamping OEM engaged MWES to design, build, and integrate a robotic resistance spot welding cell for high-volume automotive oil pan baffle production. The dual-cell solution consistently delivers fast welds while reducing manual labor and improving weld quality.

The Challenge

High‑Volume Spot Welding with Consistent Quality and Minimal Labor

The customer faced several operational challenges that prompted MWES engagement:

  • Manual welding introduced variability in weld placement and quality
  • Labor shortages and lack of trained welders limited production scalability
  • Automotive part tolerances required consistent cyclical welding
  • The baffle assembly needed to be completed in under 10 seconds per part

MWES was selected to apply its expertise in resistance-spot welding systems for demanding automotive manufacturing environments.

The Solution

Dual Dial-Table Cell with Automated Spot Welding and Reject Handling

MWES engineered two fully enclosed welding cells that operate in parallel and include:

  • Six-station indexing dial systems for both louver and diverter welding modules
  • Dual Milco C‑type resistance weld guns at each weld station to apply consistent spot welds
  • Fixture-based part holding optimized for accuracy and repeatability
  • Integrated pneumatic unloading and reject chutes to manage good and scrap parts
  • HMI-based control and automated cycle sequencing to ensure reliable throughput

This spot-welding automation delivers rapid, consistent weld application and reduces operator dependency while maintaining high-volume output.

The Results

One Weld Every Ten Seconds,700K+ Parts Annually, Minimal Labor

Implementation realized substantial performance and quality improvements:

  • Capable of welding over 800,000 parts per year, or one complete part every 10 seconds
  • Eliminated manual weld labor and associated fatigue or inconsistency
  • Achieved high-repeatability weld placement across long production runs
  • Seamlessly integrated into existing cell layout without requiring new tooling or infrastructure

By replacing manual spot welding with automated dial-table cells and precision resistive welding, MWES dramatically increased throughput and quality, while minimizing labor involvement.
