I've heard they continue to have had big steel welding problems. Earlier cars were composites and aluminum but ramping up production of steel cars is a very dif

  Interesting to hear someone having problems welding steel instead of aluminum. Generally Al welding is much more difficult than steel.

    Robots seem to be better at welding aluminum than unskilled humans, they appear to be ok with spool guns and adhering to consistent tolerances and settings. Until now Tesla has mostly been attaching composites to aluminum monocoques using relatively low production run specialist car building techniques. Banging out masses of low cost cookie cutter cars is a different dynamic involving lots of spot welds...

  That article's only evidence is some sparks flying that look exactly the same as the welding in other mfgs videos. The link to the cheap spot welder is a bit over the top as well.

  > Poor welds can increase the damage to a vehicle in an accident, and can lead to rattling and squeaking as the car ages, Tracy said. That sounds interesting. Subpar welding will be impossible for buyers to spot and could take years before becoming obvious.
