You should never, ever weld on a truck frame. The only exception is to extend the frame towards the back as is done on some motorhomes but you better have a welder who is certified by the AWS for that particular procedure. The heat from welding will affect the temper and strength of the frame.
Slight change. Maybe
You should never, ever weld on a truck frame. I have cut a 350, a 250 and several class 8 trucks in 2 replaced or added sections with no issues. I have also had to plate a few factory frames on class 8 GMCs when the owners tried to do the same work as I was with my spliced 9000 Fords. (GVW 67,000. GCVW 110,000)
