i am not basher nor supporter, i've been working in 1 of the reputable local assembly plant for Japanese vehicle before.

judging from the photo, i may conclude

1. yes it is spot weld, nothing wrong with that.
2. the quality of spot weld is not acceptable by JIS body shop standard (pre assemble the metal part before send for paintworks)
3. 1 of the photo clearly shown misalignment of the 2 panels, should the panels involve mechanical movement, ie window glass railings, this may distort the movement thus case premature power-window issues.
4. the poor welding finishing may cause water ingression and develop rust in future (as you can see on top right photo, there might already be some rust mark there)

Just my 2 cents. Hope that proton can improve in this
