as a quality engineer, this weld is acceptable. why waste money doing full weld when u can just tack weld and get the strength needed?
door frame is not structurally integral to the car so it not critical and that weld is probably stronger than the base metal surrounding it.

I'd love to see the welding on other more expensive cars.

   

i mean take the pic at far and show its original pic and proof that is preve...

coz i cant figure out where is the poor welding is also...

It is Preve.

Whether this constitutes poor welding or not, this question is best to be answered by those in the industry.

hmm no one bother to check whether honda or others to see if its the same? 

it looks more like a tack weld to me, spot weld, absolutely not~ spot welds in automotive industry are mostly automated with robotic articulated arms. . .

and what do you know about welding ???

there a reason why not to weld the whole thing

you simply simply say shit welding but i doubt you cant even know how to weld

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

i've seen that picture everywhere on the web way before preve.
nice try ts

Do you know how to compress the photo before upload it?

If you email this to your client, he will scream and curse you.
