I am repairing a hydraulic tank in my old bobcat skidsteer. Problem is..the tank is part of the frame cross member, so replacing it or for that matter, cutting it open can not be done, unless I cut other frame cross members out of the way. I am trying to avoid this...the tank has a number of deep surface pits in it. One pit was deep enough that the tank started to leak. There is no pressure in this tank, just ATF fluid. I welded the pitted area ( but burnt through, as it is very thin due to the pit, but I managed to weld it up) would brazing be a better fix? what could I do to prevent other pits from leaking? Braze over the deep pits now, before they leak? I do not have good access to weld a new cover on the tank. My plan is to use a really good gasket sealer and seal a metal plate over the pitted area. At least I could remove it in the future if I need to make another weld....any ideas are apprecated. I really would like to hear opinions on brazing the pits verses welding them....I have no experiance with brazing.
