welding parts with increased difference in thicknesses

[seryoga]

Originally, we were GTAW-welding two tubes together, 4130 steel: .750 x .049 and 1.00x .049.(within a truss structure). Now the latter one is almost twice as thick: 1.00 x .083. Should we expect any problems? In fact, if no problems, I need some facts to submit to a cerification body, showing that there are no structural problems to be expected, after thickness has increased. Are there any sources that can be recommended, to substantiate that?
