RE: spot welding performance on crash test
Safety related parts- requiring a minimum nugget size, penetration ratio and defect level.
General use- requiring a minimum nugget size, penetration ratio and defect level but of different parameters to the above.
To determine the quality of your welds there is the old chisel test or the more modern ultrasonic procedures available in some countries.
I suggest that if your welds are burnt or undersize at the front end of a vehicle crash worthyness and possibly long term durability would be affected.
