RFP Title

 

Quantitative, Non-Destructive Weld Inspection
RFP Description
NineSigma, on behalf of a global Tier 1 automotive company, invites proposals for groundbreaking technologies capable of quantitatively and non-destructively evaluating welds, both internally and externally. Of particular importance, the technology must be capable of detecting and measuring the transition between base material and the weld itself.
Background

NineSigma’s client uses gas metal arc welding to bond ferrous metal sheets into a variety of assemblies. This work produces tens of thousands of individual welds each week.

 

At present, NineSigma’s client employs a destructive evaluation procedure to evaluate welds: a number of assemblies are set aside and then cut into segments to allow for a detailed inspection. This process is time-consuming, wasteful and expensive – a team of technicians is required to inspect nearly 2 thousand welds in a 1-week timeframe at substantial cost. The purpose of the inspections is to verify that the welding process is adequately bonding the base materials and to measure weld parameters such as leg length, penetration, throat length and weld depth according to customers’ requirements.

 

The client has previously investigated potential technologies, including ultrasonic testing (UT), phased array ultrasonic, x-ray radiography, computed tomography (CT), electromagnetic acoustic transducers (EMAT), shearography, and infrared tomography. While ultrasonic testing and CT demonstrated the best internal inspections, they were not capable of measuring all desired attributes, especially weld penetration.

 

To ensure product quality, reduce costs and inspection time, NineSigma’s client seeks innovative methods to accurately assess welds in a quantitative and non-destructive manner.

 

Anticipated Project Phases or Project Plan

Phase 1 – Evaluation

  • NineSigma’s client will evaluate all proposed technologies
  • Q2/Q3 2018

Phase 2 – Demonstration

  • Selected technologies will be invited to demonstrate proposed technology on production samples (testing location to be determined)
  • Q4 2018 into 2019

Phase 3 – Implementation

  • Successful technology/ies will be implemented in client production facilities
  • 2019 - 2020

 

Criteria for Moving from Phase 1 to Phase 2

Client will consider for advancement an approach that meets performance criteria with acceptable economics and pathway to commercialization.

 

Key Success Criteria

The successful technology will:

  • Detect and measure defects:
    • On the surface of the weld
    • In the interior of the weld
  • Detect and measure boundary layer between weld and base
  • Measure the following weld parameters:
    • Leg length
    • Penetration/Fusion
    • Porosity
    • Throat length
    • Weld depth
  • Precision: at least 0.05 mm
  • Target inspection rate: 5 - 15 welds per hour
  • Retain scan images
Possible Approaches
Possible approaches might include, but are not limited to:
  • Next generation:
    • Computed tomography (CT)
    • Eddy current testing
    • Electromagnetic acoustic transducers (EMAT)
    • Neutron testing
    • Phased array ultrasonic testing
    • Phased contrast X-ray imaging
    • Ultrasonic testing (UT)
    • X-ray radiography
  • Systems which incorporate multiple sensing technologies into a composite scan
  • Other novel sensors capable of providing non-destructive weld evaluation
  • Weld doping to improve defect detection
    • Must not negatively impact weld performance characteristics
  • Imaging systems to inspect weld:
    • During the welding process
    • Post-welding process
  • Non-destructive evaluation technologies from other industries

 

Approaches not of Interest
  • Laser welding combined with imaging technology
  • Approaches that cannot detect sub-surface defects
  • Approaches that cannot accurately detect all desired parameters
  • Approaches that require destruction of the assembly
