If the frame is heat treated steel, then by all means DO NOT weld. Doing so will change the physical attributes and crystalline structure of the steel at the weld location due to the high temperature of the weld. Every semi-truck frame I have seen has a "Do not Weld" warning affixed to the frame in a prominent place along with the fact the frame is heat treated.
