Broken Fork on Forklift

A Front Loader Fork lift had a broken fork.  Some folks say they don’t have much luck with welding the fork on  a forklift back together.  I do my best to not depend on “luck” to determine what I can or cannot do.  There is a specific procedure to weld these together.  First you must make certain the forks are parellel and they are lined up right.

Then preheat the forks to ensure the weld does not cool down too quickly as the forks are being welded.  It is critical that the filler rod is tougher than E7018 because the forks are typically a medium carbon steel and tougher than mild steel, I used E10018.

Here I used the back of my truck to align the forks, as if the truck needed the additional weight on it, it held up alright.

Repair Cracks in Front Loader Bucket

This project was off Eight Mile Road in Stockton.  Mark from Blue Iron, Inc., www.blueironinc.com, called and asked that I repair the cracks, there were several.

This was a crack around the lift pin boss

 I used an air arc, or arc gouging process to clean out the crack.  Sometimes the crack does not go all the way through the material and it is imperitive the crack is removed from the material or gouged out then welded up completely. 

Same crack repaired.

Some welders like to use the Stick welding process , SMAW, to weld these cracks up typically a rod with the 7018 designation.  This process is adequite, it provides a strong weld and when done properly the crack should not come back.  However it has one down fall and in my opinion only one, its speed.  I was able to utilize the wire welding process, FCAW, I used NR 232.

There were a total of 12 seperate cracks with a total of about 55 – 60 lineal inches combined.  This project was completed 2 – 3 hours faster because I used the FCAW process instead of the SMAW process.
