Company: Mercedes-Benz Canada Fuel Cell Division

About Company:

Mercedes-Benz Canada is the Canadian subsidiary of Daimler AG, the world's oldest car manufacturer. Located in Burnaby, British Columbia, Mercedes-Benz Fuel Cell production facility is responsible for Daimler’s global production of fuel cell stacks – the technology at the foundation of alternative propulsion strategy.

Project Description:

The aim of this project is to characterize and assess existing welds, map locations and types of failures.   Leak testing of welds It also aims to characterize welds by existing metallographic techniques. 

This project also aims to develop new techniques.  Focus is on fast techniques and in-situ analysis.  Mechanical testing maybe needed.  Ultrasonic methods should be explored.

Background and required skills

Research Objectives/Sub-Objectives:

  • Characterize welds on existing components
  • Cross section component and assess welds at different locations with etching
  • Weld integrityIs the weld strong, examine HAZ
  • Examine leak tightness
  • Map locations and see if any patterns arise so weld sequence
  • Pareto weld failures and locations
  • Assess leak tightnessAssess new component on new welding fixtures and characterize failure
  • Develop measurement method for weld strength on original component
  • Possible mechanical method (destructive)
  • Possible (non destructive test) e.g. Ultrasonic sensor
  • Brainstorm and develop any other options
  • Assess literature and state-of the art in line weld characterization
  • Measure weld strength of current plates and future versions

Methodology:

  • Welding metallurgy, in situ characterization of welding property

Expertise and Skills Needed:

  •  Welding and joining, material selection for welds and joints, calculation of properties for welds and joints, mechanical analysis of joints, and design of welding and joining procedures.
