Hi everybody,Can i weld a broken hydraulics shaft? Have you a special procedure for the pre-post heating and the kinds of smaw rods or wire?Thank you for your answer!
Reply:I dont think those are high carbon,  at least not on small scale stuff.but by the time you weld it,  straighten it, have it re-machined and re-chromed you could have bought 3 replacement rods..

Reply:Yes, i know...Is that i weld heads on cylinders sometimes
Reply:The only input I can give on this I machined up a whole new chrome rod from blank chrome bar then welded the old eye onto the new rod. I machined the end of the rod to give me a cone point where it would be welded (the rod material was 20MnV6). I preheated before welding to reduce post weld distortion, and made sure I had plenty power on the mig. I definitely didn't want any pretty looking mig welds with s..t fusion. I gave four tacks of high power to get decent penetration and check the eye / rod alignment before commencing the weld. I used the lathe to rotate the bar while I welded it, but I did a test run on some scrap bar first to check the lathe speed was OK.Anyway that weld has taken multiple tensile pulls and hasn't gave way. As for joining a broken bar I wouldn't even attempt that unless the join was external to the cylinder and you could keep the alignment pretty close.Last edited by mancavedweller; 11-24-2012 at 10:17 PM.
Reply:The eye to the shaft are butt welded from the factory..As long as it's tight all is good..Decent penetration in the "V" and you are good to go....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:If you are welding an eye back on it, just vee it and weld it.  You have to make sure its still long enough it won't self destruct when it retracts. After welding, a simple file will knock off any high spots or spatter and just slide over the chrome.
