Crack in repaired frame

Is that outer rail Steel or aluminium ???????

 

Looks like the welder was on crack!

 

Lol!

I was looking into stretching my frame a while back. Google "stretch truck frame" and go to the first link on diesel garage. Pretty good discussion over there.

Oh, and I agree, whoever welded that should be smacked on the back of the hand with the pointy end of a slag hammer.

 

No kidding. That's the worse weld I have ever seen.

 

In order to properly repair a crack, you clean the crack, take a metal plate in a diamond pattern the same size or larger than the crack, weld that plate to EACH side of that cracked area. That way should it fail again it will have to fail across two plates before it fails again.

I see that someone covered the crack passing a welder back and forth. That person should have been shot. And Im not even a welder.

 

Based on the thickness of the original frame I'd be willing to bet that frame is aluminum. Not many guys are skilled with welding aluminum. I'm not an experienced fab guy by any means but that fatigued area needs to be ground flush, then ends of crack drilled to help prevent the crack from spreading. Vee'd out from both sides and welded from both sides. A few more bolts into the reinforcement sleeve will help prevent it from moving.

 

Looks (to me) like an ancient aluminum frame that someone had a steel liner rolled to fit. That aside; I would respectfully differ on welding a liner to the parent rail.

 

Somebody needs to be beat with a hammer. Lol. For not welding it properly.

 

I have to tell a story about my so called brilliant company, so might as well be here...
We had a truck yesterday literately fall apart, a weld on the frame broke open. and collapsed the frame.
The brilliance was it started life as a single axle truck, got the frame extended and a second drive put on. Not too bad a ting really, but I'd not want to drive to. That wasn't the bad part, the company for some reason decided to take this tractor and plate it heavy haul 4-5 axle trailers and 105K pounds. Ok, not only am I surprised the frame lasted a few years, I'm surprised the motor and tranny could even get it up to speed...
