'67 GTX ripped in half....holy crap

[69bronzeT5]

This GTX had to have had the front end cut and replaced sometime in it's life for this to happen

      yeah think your right Cody ...   & the guy who stuck the frontend on was a crap welder

OMG  The suspension is even ripped away from the engine, wow what a hit!!!!!!!!!!

Well....to be honest, this opens up a whole can of worms.
In particular, the entire issue of welding in the process of restoring a car.

Within the realm of metallurgy in automobiles, there are numerous topics, but the one I'll mention now has to do with the strength of metal and the effects of heat upon it.

In a nutshell: the reason cars are spotwelded together isn't just for the sake of expediency. It is primarily done to minimize the effect of the heat of the welding to a smaller, localized area.
Why?
Because heat will alter the molecular structure of metal.
How?
By removing whatever inherent strength the stamped (or forged) structure may have.
Theoretically, and as an example, take a tool (like a screwdriver or chisel) or a knife, and heat it to cherry red. What happens? You remove the temper (or strength).
What is Temper? read this: http://en.wikipedia.org/wiki/Tempering


Long story short: Localized welding on HSS (High Strength Steel) or heat-treated sheetmetal (like a frame rail) will essentially remove the strength from that area.
Therefore, a shear impact at the same concentrated area will produce results such as those exhibited on that GTX.

As a last note, this is somewhat applicable to sheetmetal as well, although to a lesser extent. Frame rails, in theory, should never be welded - unless they can be retreated to original specifications.

well, from that small picture, it looks like it will just need a new subframe and front sheetmetal, but who knows... either way, it'll buff right out!

Bad welds are rampant in the old car restoration field.  Rampant.  So many restorers would rather have weak welds that look like factory job than a strong repair that looks imperfect.

That's where I saw it

yeah thats a lot of true stuff !!  even worse for that s the new cars, with thin gauge (super metal) or something its called these days
               i had to be a certified welder , for my job  
 like was said  prolly just butted & another front end on  
should always splice or fit ,  as factory ....
