absolutely ! i'm not a fan of weld on joints. one wrong zap with the welder, and the joint is history. if you need to weld on your steering shaft, i would suggest obtaining a solid shaft with the spline count of your choice. turn down a 1 1/2-2" section past the splines that will press fit into your present shaft. bevel both ends good for the weld, plus add a couple holes 180* apart for plug welds. then, use a splined joint.
gene knows welding, so please listen to him.
