ThyssenKrupp Tallent Ltd
RFLW Project: Weld Quality Evaluation
Observations from Trials and Sectioning
The trials to date have succeeded in making functional welds on all chassis parts used
Sensitivity to fit up condition is evident
Small fit up gaps did not prevent a joint being made
Characteristic of weld to sag creating a signature groove in the upper panel at gaps
In some cases this resulted in small weld cracks
Effect of such grooves on the strength & durability of the weld is being investigated
The effect of the narrower laser weld on fatigue durability is subject to further testing.
No evidence of porosity in the laser welds on the galv-annealed parts
Very little weld distortion
Potential benefit with regards to corrosion
No silicon deposits (seen with MIG) which prevent and reduce local paint adhesion.
Also less damage to the zinc coating compared to MAG on coated steels

ThyssenKrupp Tallent Ltd
RFLW Project: Weld Quality Evaluation
Recommendations from Trials and Sectioning
Design of part & fixtures optimised for laser welding should greatly improve the fit up
Will help reduce / eliminate the weld sag / crack issue
Control and repeatability of pressed parts is essential
Especially for panels above 2.0mm where it becomes harder to clamp out gaps
The welds usually penetrated through both panels, therefore:
means that visual inspection could provide a reliable confirmation the weld is fully formed.
presence of grooves in the upper weld bead could be used to:
indicate potential fit up
associated weld quality problems.
Possibility laser welds can be more reliably visually assessed than MAG or Spot welds
Further investigation is required to gain confidence in this

Future Project Work & Plans
Current On-going and Future Planned Investigations:
Continue to develop and refine cost models based on increased experience
Carry out facility level comparison of RFLW versus MIG (not just single cell based)
Refine the area comparison and cost comparisons out of the above studies
Manufacture of further front sub-frame parts to fully finished level for rig test at TKT
Part RFLW and part MIG due to current part design
To assess strength & durability performance against existing parts & processes
Manufacture of further rear sub-frame parts to fully finished level for rig test at TKT
Fully RFLW to replace all existing spot welds, some projection welds and most MIG
To assess strength & durability performance against existing parts & processes
Preliminary discussion underway with OEM about trying to put part on vehicle test
Investigations into clamping fixtures and panel control to minimise gap issues
Demonstrator Design project to re-engineering existing part to be suitable for RFLW and
conduct full test, feasibility and cost comparison (longer term)
