    Default DS - panel thickness for welding?

    I'm sure it will have been covered here before, but i couldn't easily find anything. How thick are the body panels (doors and wings) on a DS please? Was it consistent through the Ds lifetime, or did thickness/ quality reduce near the end of production?

    Always very thin ... not as bad as a 2cv (that is like trying to weld aluminium foil). I'd have to measure one. Probably 1.6mm ?

    Most external panels are about .8mm. We used 1mm cold rolled deep draw to fabricate a replacement boot floor.
    1.6 is very thick!

    Thanks gents. I know that modern car panels are only about 0.8mm - which makes them tricky to weld. I just wasn't sure whether, being older, the DS panels were slightly thicker. Even a step up to 1mm makes a big difference in terms of welding.

    Door skins are made of a heavier gauge steel than the door frames. They have (some) strength due to the shape. 1mm will suit most of it.

    Shane is thinking of a Simca Gerry! Boy that "Some car this Simca" had thick panel - never seen anything like it since. It probably was in excess 1.6 mm. Without measuring 0.8mm would be about right.

    Simca was a real dud, every panel was welded onto another

    I have done some repairs to D front Guards! .8mm is the thickness.

    Come on Driven - it was not a dud. Did it not win the Armstrong 500 some years back!

    In 1960, class win in Class B, not only the win, but second and third as well and the leading Simca was only three laps behind the Class C winning Peugeot 403

    There is panel steel and mild steel. Two completely different materials and they work/form/weld differently.

    I am no expert in this area, but was advised by an engineer who's opinion I value, that I should use cold rolled panel steel when patching forming panels on the 404.

    BRIGHT SHEET


    AS1595 is the standard grade steel in Bright Cold Rolled Sheet. Cold rolled sheet is sheet metal that which has been rolled to thickness at a low temperature in a continuous cold rolling operation. This process will produce steel with closer dimensional tolerances. Cold rolled sheet is a workable/soft material that is used in panel repairs on cars. It has no scale and a bright finish.

    Just one, of a number of sites that have information on the topic.

    Hope this helps.

    All very helpful thanks! I've bought myself a welding machine off Ebay and, at it's lowest setting, is running at 20amps. So I'm hoping that, (with lots of practice on my part!) it should be able to cope with 0.8mm metal.
