  • Welding forklift forks?

    Has anyone successfully weld repaired a broken fork? I broke a fork today on my tractor. The tractor weighs roughly 8,000lbs and a careless move on my part put a backwards prying type of force one of the forks. Anyways, it broke clean off, sounded like a gun shot when it went too. It broke up above the bend. I'd like to weld it back up, but being a spring type of steel I'm not sure if it will hold together, and I don't want to fix something just to have it come apart again, possibly making for a dangerous scenario.

    Thanks in advance.

    I have had great success at welding forks. The biggest was for a 966 loader, and quite a few smaller warehouse types. I have a PDF file on how to weld T-1, but I don’t know how to post it. Here is a link to Lincoln’s site.

            That is interesting, I never would have thought of 7018! I always used 110-18. Preheat to 300°, peen each weld and wrap with insulation, to let cool as slow as possible.

              For some reason I thought forks were of a spring type of steel, not just T1. If they're T1 then I've got this cat by the tail

              Thanks for the input, its appreciated. AA, that's how I broke this one, moving a log at my mill, and it got me thinking, that they would be even easier to break come winter.

                When i worked for my father years ago there was only one rod we used in the shop. And 7018 was it. My uncles forks were 3" thick and about 8" wide. We torched the vee and tacked them square then ran an angle brace to keep them from pulling. Some pre heat and about 4 or 5 hours of welding welding one side then flipping to the other. I saw some that had been there at the sawmill 15 years later and they were still fine...Bob

                    Osha and Cal osha strictly prohibit welding or drilling holes in the forks.
                    As quoted from Osha
                    Modifications and additions which affect capacity and safe operation shall not be performed by the customer or user without manufacturers prior written approval. Capacity, operation, and maintenance instruction plates, tags, or decals shall be changed accordingly.

                    I can't believe you guys would even consider welding a fork back together Thats just asking for trouble.
                    Our company just had a technician killed by a fork lift that failed. The only thing the tech did wrong was stand to close to the load when the lift did fail But how often does that happen.

                              Well said.

                              I understand that some would like to do this for the sake of it being their own equipment or other reasons. I just look at it this way If there was ever an incident Osha would for sure notice the weld on the fork even if it had nothing to do with what happened. Plus i would never trust that fork again
