Well here's a little job where I remembered to take a few photos. It's an old 12 ton tipping trailer with a seriously worn out towing eye - would you trust this this ring pulling 16 ton up a hill?
Well I didn't get a photo right at the start, the drawbar on these is an enclosed box which has to be cut open to reveal the rest of the eye assembly.
Having cut the top out I then cut the sides at the bottom to bend them out a bit. This isn't essential but it does give more room to work and more importantly allows you to get the right rod angle for the fillet weld on the new eye.
The old eye is chopped out with a combination of a 9'' grinder and a gouging nozzle. It takes some doing as a tiny amount of weld is enough to hold it in place even when beating hell out of it with the sledge hammer. Cut or gouge too deep and you take a lump out of the drawbar, a little care and patience is required.
Eventually it's out and cleaned ready for the new eye, the only thing that I haven't done for the photo is run a bit of weld in where I gouged too deep:
Now I begin welding. I have done a far better job than the previous person who's welds had a lot of porosity!
Preheat is used, the root run is done with a cellulose rod (sorry, no photo of that) and the rest is with 7016 from a vac pac. It 'ain't going to drop off!
Right, now to weld up the sides. V'd out, but I couldn't really say that the joint prep was brilliant...
Bear in mind that this is in the horizontal position:
