OA Filler Rods

admin

I am trying to repair a rusty tractor battery tray which was originally made of 1/16" sheet metal.  It is mostly good, as there are only three small spots with deep pitting.  I am planning on cutting out the thin spots and welding patches in flush (I am trying to keep it as original as possible for the restoration).  I have heard of people using RG45, RG60, RG65, ER70s6, and coat hanger as filler material.  Which one should I use, and are there any other ones that I should know about for welding steel?  I don't want to braze it.
Reply:Is this a xx00 or xx20 series JD? I have two of these and have replaced all of the battery boxes. Once I cleaned them up to bare metal, there wasn't much left to work with. Coat hanger works for me, just make sure everything is very clean. I was surprised with how little metal was left after a good wire wheeling.Lincoln Precision Tig 185Lincoln Power Mig 256Hypertherm PM 45Everlast 140STSmith O/A
Reply:Stick with the RG series fillers. RG45 would be my first choice for that with RG60 being second due to workability after welding. Since it was previously rusted metal, give yourself about a 1/2X  ( excess acetylene feather 1/2 the length of the inner cone ) reducing flame to help consume the oxides in the pits.-AaronP.S.

Reply:It is a Case VAC-14 tractor, and the battery tray is built into the back of the dash.  I am very fortunate to have found one with only two or three bad spots.  Most won't support a battery anymore.
Reply:Cleaning up with a light duty sand blaster before welding will help the weld quality.  If you could tig it would reduce the heat input and distortion.Dan
