  • Or you can do it yourself if you know welding work. Weld the crack all the way around, with the frame tightly secured to prevent warping. Now grind the welds flush.
  • Put a patch plate of steel. It should be at least 1/2 the thickness of the frame steel over the weld. Then execute a thorough fillet weld around each plate.
  • If you can’t put a plate on one side, don’t grind the weld on that side back. It will be twice as sturdy as the original frame if done correctly.
