Ken - while welding Chrome Moly is no trick - just use mild steel rod -
be very careful about doing it, and perhaps consult a professional
engineer. I would not use an electric welder to 'run a bead down each
side' - I would gas weld it, as the temperature transients are much mre
severe with electric welding. Or .. conversely .. reheat and draw the
metal after the welding.
