Dipper snapped

[selftot]

It happened digging out a large rock.

I expect a good welder can fix this but is there a reason not to go that route ?

I know a good welder - this is beyond my skill level.

FYI-The black line on the cylinder is a zip tie.

easy to repair, four fish plates, four hours

Wow, never seen that before, if it was mine, I’d pull it all off and do some heavy horizontal arc welding

Impressive!

I'm no expert on metal fatigue, but that break seems to have a lot of rust on it. No shiny metal anywhere except where paint is flaking on top side.

I hate it when my dipper snaps.

What Jay said - plates and weld er up.

The corner seen in the photo is not nice at all. At the edges on the other corners, the metal looks clean.

Metal fatigue is why i asked the question. The work i was doing was not excessive and I believe this problem had been building over time - just waiting to happen.

I agree with might as well reinforce it while the welder is hooked up.

The break is remarkably straight!
Welding will repair that however I would carefully inspect the interior.
The metal reinforcements should be cut to ensure proper overlap and yet look good once painted.
Goodluck with it.

Wow, thats quite a "crack"

I agree that a good welder should be able to take care of that.

Hell, I would even attempt it myself.

I would pull it off so I could weld it on a table. Then cut it apart, grind it clean and weld it with some “strategically placed” reinforcement plates.

Thats just me though…….

It's been slowly failing for some time.

Interesting that a stress riser was created at the end of the weld for the gusset plate even though the weld was extended beyond the corner to prevent that! I see no issue with repairing this.

If it's not completely broken in 2 pieces, I'd Vee it out a bit / put a chain or come-along on it and close up the gap and tack weld it back into position first...

THEN take it apart and put it on the bench and fully weld the crack/grind it flush/then fish plate it and weld it up better than new.

Not a difficult job. If you delivered it to me I'd probably charge $500 .... plus the cost of 3/16 or 1/4" plate if I didn't have some hanging around.
