    Default Pictures of Boom repair...

    Was going through my camera, and I came across a broken Takeuchi boom I fixed, welded this up about 2-3 years ago. This was done with a LN25 and My maxtron...Wire Outershield 71, .045...All welding was one with the boom attached, so not in postion..Funny thing only reason I took pictures was to contact takeuchi and figure out why...Now I work for the dealer which sold it..

    Nice welds,
    Just one comment on booms fish plating like this, on each rounded point of the diamond shape you made, you shouldn;t be welding around the round end but from the straight edge you keep welding straight off the fishplate on to the boom end flare it out. Kind of look like this coming out of the rounded end point )(

    On some booms yes that is a better way, but on small track loaders, your best bet is do the full weld, looks bettar, and does not draw attention to the repair. I actually did both sides. Anytime any welding is done on a boom it kills the resale, the newer machines actually have these gussets in them. Just like I welded them in minus the bottom piece.

    On small little boom, I guess it doesn't matter. But it is a good habit to do it the right way regardless of how it looks and what ever the size.
    One other pointer is the fish plate should never be of a thicker and harder metal then the metal it is going to be welded on .
    Again, very nice weld.

    On larger booms you will not see my fishplate as I put the plate inside the boom, If it means cutting the crack out to fit the plate then so be it. Then I use the plug welding techique. Again fishplating booms kills resale. Only time this gets tricky is excavators tend to have ribs inside the booms.
    Also Im always amazed at how thin the booms have become on large excavators, last boom I did was a pc400, 100,000lb class machine, boom was hardly 3/8 thick! Amazing how strong steel is when engineered!

    Hey Kevin: You run mixed gas or straight CO2 with 71M? I've run both, seems like it runs better with 100% CO2.
