Welding a bumper

[tubman]

I never had a problem welding ed rails; they make great battery boxes. Maybe it's because I use an old stick welder?

Maybe those hard to weld bed frame rails were "work hardened".

Maybe those hard to weld bed frame rails were "work hardened".

And with lots of "stress cracks"

Ok so I read this post and start working on my 1939 bumper and it shattered. My bumper has extra holes where something was bolted on. Before welding up the holes I put it in the press to push a dent out and the bumper shattered like I was trying to bend glass.
YMMV but it seems this bumper is very brittle so now I have to weld it back together but in my experience with steel like this (bed frame angle iron) it will crack right at the weld.
Do I persist of try and find another bumper?

So I am back to trying to repair or get my bumper repaired it needs to be straightened and welded
