Hi all,
I've got 4 brackets (12mm) to weld to an agricultural axle for a slurry tanker, the axle is 70mm solid bar and is brand new so I'd rather not muck it up.
I've not posted this in mig/mma/automotive sections as it applies to all I suppose!
I'm wanting some advice as to best practices welding this heavy a section. I've access to a 250a mig and a 200a mma welder (same inverter machine) and have oxy/propane to preheat but only a standard cutting torch no rosebud.
I realise preheat would be advised but I doubt they bother in trailer factories like Marshall and Fleming, and I'd ideally need to dismantle the bearings etc as I don't want to damage them with the heat, which is a lot of faf tbh.
Basically can I get away with just welding the axle without preheat and will I be ok with multi pass mig as I'm more comfortable with it over mma. Though I have plenty spare plate to practice getting a good weld on/tuning settings etc.
Any help much appreciated,
Dan
