Hey thanx Gary, ..... good question! I had that exact consultation with the tech working on that drive train. It's a little hard to see in the photo but i tried hard to keep the build up height to a minimum, but also concerned with retaining as much strength as possible. I advised him to go ahead a grind it down if necessary, but the oil seal ended up sliding quite nicely right over the weld! The root pass was hot, going for some real penetration and spread across the foot of the bevel. The weave was done with out the benifit of a mechanized device so i had to just work manualy around the circumference, welding 1/4-th at a time, opposite each other to try and control any warpage and minimize any undue additional heat input. No cup walking so just tried to keep the weave fairly uniform. Thanx, Lou
