Default all front panels off the car, anywhere to add some weld?

I will have my 1992 DX naked by tommorw night for some paint, is there any areas that would benifit from some additional weld?
I should ahve taken pics but forgot. Where i was thinking was where people put the triangle braces behind the front fenders. There are some places there that are either just spot welded or stmaped together.
any insite
thanks

What are you trying to accomplish? Is it legal for your class?

Reinforce the battery tray? Like it's posted above, what is legal for the class? If it's a production car, I've seen some nifty cross bracing, but you'd be best served talking to someone about how-to. The fit was really tight.

check with rally car guys.. they normally "seam weld" the chassis.. i'm guessing this is taking whatever is stamped/glued together and weld it all!!

i'mma do this to my 86 when i get the chance to.. it's structural integrity is lacking slightly after 18 years....

i just run track days and want to do some autocross this year. I know it might be overkill but i figured it could not hurt since it was apart anyway and the welder is jsut sitting 10ft away :D

any idea how to get the glue **** off?

Uhm... sounds like a bad idea unless you really know what you're doing.

i am not gonna start cutting things and welding them back together, what i will do though is run a beed of weld where there is only spot welds or where there are seems punched together.
i'll post some pics tommorw night of what i did

i'll probably be bumped to some crazy open class right? No matter it;s already too modified for anything but, i am sure.
This is just my fun car that i drive most days in the summer and take it to track days, and i'll try out some autocross too.
BAsically i do whatever i want with the car to make it faster or better

You fail to understand something here. The reality of seam welding is a very specialized piece of business. Not only that, you may make the car illegal for any event other than open track and certtain classes that allow this modification. I would take a look at the long term plan for the car and decide if it is to become a track car or remain a daily driver/occasional event machine. If a track/HPDE/autocross car-then please read the rulebooks before taking your welding machine out. For that matter some rally rules may not permit seam welding. As I suggested-be very careful where you apply seam welds-they can cause chassis failures if you stiffen things too much.

Enjoy your car and the events that you plan to go to.

You'll be glad you didn't do it - and should already be...

Having participated in the seam welding of a couple of rally cars, I can tell you that it's a lot of work. It will also likely result in the early rusting of a tub (particularly up north). Understand too, that we don't do this to rally cars to make them stiffer: We do it to make it less likely that they will unzip when we beat the crap outta them.

Care to elaborate on that a bit further?
thanks.

If you dont seam weld, after 12 or so good rallies, your shell is toast.

Gotta get a new one.

The constant banging and vibration that rally cars see can fatigue the OE spot welds, causing them to break. If one breaks, more load is carried by those next to it, so they fail or sheetmetal starts to crack. If enough of them give, the car litterally comes disassembled.

Seam welding just reinforces the connections between the OE pieces of sheetmetal, providing more weld area and therefore more resistance to cracking. It doesn't make the shell enough stiffer that anyone will notice in most situations. If one were using really high spring rates on a road racing car, the instantaneous loads might be high enough to warrant seam welding but it's not legal in many classes.

It makes NO sense on a street or track car.

ya those where the 3 reasons i did not do it,
1 - alot of grinding, and wleding such paper thin mental is a pain.
2- I was worried about the rust (even though it;s only driven in the summer), and 3 - man is it alot of work LOL i just didn;t have the time to do it right

now i am very glad i stopped after a couple spot welds
