i think need to quote back what i said coz still many professional welders here, hu...hu...
erm, if not mistaken, prtn already used one piece door stamping gen2, tailor welded blanks door saga,exora, and preve i think, door sash + doorpanel, using double spot, robotic plasma welding, new n latest for prtn, better weight, better design for sash n better strength.
I thinkla :-), dengor2 khabar anginla, ingress corp supply the door to prtn preve. So, better ask them lah, ha...ha...
The door sash is made using roll forming method, only using this method, u can used advance high strength steel(ahss) aka ultra high tensile steel(uhss) as the material coz in cold forming method, its really hard to shape ahss to complex shape coz of its rigidity.
Then the door structure is normally used high strength steel low alloy(hsla), and the trapezoidal impact beam, unique to proton n lotus, start in satria neo n upward(not tabular impact beam as some others using) inside the door also ahss using roll forming.
So, combining the door sash n door panel is using robotic(not human, unless humanoid :-)) plasma welding, double spot, for strength n better corrosion resistant. Ops, forget to mentioned, all high strength steel using in car are galvanised steel(corrosion resistant coating steel), yup, the whole body n panel, deep into pool, electro charged, the pool is in tanjung malim, maybe u can visit for swimming n diving training :-). Plus, its painted in white(thats why they called it body in white as the preve chasis during power of one event), then another layers of colors paint.
So, in other words, using this method, the door will enhance its strength by combining two type of steels(ahss for door sash n hsla for door structure), n door sash is stronger than before as in using tailor welded blanks. Coz previously, only being protected by ahss impact beam inside the door, but door sash still not as strong as ahss(trip or dp), but now, the whole door has the same strength. Yup, i think better they (prtn)conceal with rubber or plastics next time, so that people will not do their own professional analysis coz they only familiar with house grill welding, not robotic plasma welding.
I think better those who curious just google for image using plasma welding, spot, how is it look like, the marks from plasma welding.
yeah, tell that to diamond boy, buy in my opinion, i also a bit worried. looking at the so call welding, it is not so much on the welding, it is all about the finishing, if you can have lousy welding but great finishing, the product will look nice also, the eyes see everything,
i also agree this car, has much much more to improve, but within the proton range of products, it is the best so far.
still again, we not comparing this against inspira and persona, we are comparing Forte, dugong, siti and so on within that price range.
what i think most of us dont like is that, proton, in the last years were making half hearted cars. Mass market, no safety and crappy quality, and protected by Gomen, so many op not to get one and rather buy the rip off J's which we see on the road.
IF proton was making great cars with great quality, selling at about J and Siti price. i am very sure we or most of us will buy one and support the gomen or local car market.
like japanese, they rather buy a toyota, cause they are proud of their product. Why buy a german? when my local product is as good,
Here we are not the same, we all know, but IF proton, makes great quality car;s cars that dont break down easily, i am very sure we will all buy them, we will even buy them in other countries, because we know the quality.
Here, terbalik pulak, Malaysia model, no airbags, no this no that, cheaper plastic, useless performance. Oversea export, proton cars. Comes with airbags, come with auto sensor this and that. great quality plastics and so on.
So how? DSZ ? u wanna make malaysian proud and buy the Preve, improve the quality. if toyota and honda can do it, or even Naza can do it. Why not you? Because u got the most back up, make us all feel proud owning a proton. Not by bashing u useless.
u should know that most ppl buy a proton because they cannot afford other makes at the moment, But they swear that will never buy a proton once using a proton. That is why u got a lot of bashers.
IF you make a proton my first car, my next car also i want to buy a proton in a malaysian consumer ,mind, then i say u are the real Steve Jobs , the god of marketing in Malaysia.
2 to 3 cents only, my feeling towards the company. i love the preve, but i still doubt it, my heart still tell me, if i buy i may regret, so make me feel i wont regret.
