Welding the frame rail?

Hi guys, what type of steel should I use to weld the frame rail! Mine is rusting out at the elbows in the front.

Thanks in advance

if it’s hard, and you can’t bend it by hand. DO IT! :slight_smile:

I used square stock. Cut it open and trimmed to fit. Basically boxed the frame.

I would say use an HRS sheet that you can get at most metal shops. you want to use a softer metal so that the weld will just pull the new metal more then the old metal. and the softer metal will be cheaper, so I would say 1/4 inch HRS sheet would be the best/easiest.

i used 22 gauge steel…bought a sheet 3 ft by 3ft at crappy tire…its worked good for me…

This works I’ll be going by the metal refinery tomorrow to buy what I need.
Once I fix this i’ll have a minty fresh 240sx!
