What type rod do you use when welding chomoly tubing?

Thank you, this is for a repair and will be a big help.
Actually I would NOT suggest ER series fillers for OA welding. Many of the alloying elements in the ER fillers are un-needed in the OA process and just lead to excess sparking etc.
RG-45,60 or 65 are suggested to be based on joint configuration, material thicknesses and heat treatment if the OA process is used. ER70 series are suggested for the TIG process.
RG-45 for sure. Don't waste your time with electric rod for O/A. Been there done that.
Hey, what keeps us from brazing things together with one of the high strength brazing alloys? Race car person said braze joints were more flexible and resistant to cracking. And those joints have to be lot easier to get right. Tack-weld the frame together then braze over that for the best of both? Just a thought. Guess that's why Young Eagles run away when I offer them a ride?
The journey is the reward.
I don't know of any sanctioning body that allows brazed joints on a race car chassis.
