fixing tractor loader

What do you mean by grinding the start and back stepping on the welds? ?

Sorry but ain't %100 sure what you mean

Grinding the starts/stops is done because that's where the weld is often bad. If you stop welding, then re-start the weld, you have a start and a stop in the same place. Twice as bad. With MIG you may have a cold strart, and when stopping, you may lose gas coverage while the puddle is hot. With stick, you may not have the rod up to tempature right away at the start, and at the end, you might leave an unfilled crater.

Grinding away where the weld stoped gets rid of the bad part, and striking the arc for the re-start ahead of the tie in point will let the rod (stick welding) get up to temperature before you start making the bead. This will reduce the possibility of having defects in the weld.

Here is a good example of feathering the start, and stop of a weld. This was on an aluminum gas tank I built years ago.

Unfortunately I can't see any of the pictures on the app. Won't load abs can't view them off off my phones Browser.

Ain't going to try to reweld anything because it seems to hold but will try to grind down the ends after my plow truck is up and running. Thanks a bunch for the info shield arc!!

I think you could weld better than that.

Who me? Nope that's as good as I can do, I'm just a hobby welder.

And if your talking about me. I can't weld. I had my dad weld it in his sheet metal shop

Sure you can weld. I have only been welding a couple months ( a real couple months unlike shield arc). That weld was pretty bad, with a small amount of practice you could have done better.

The welding wasn't mine.

I've only welded twice in my life. First was at a job where I had to tack weld duct work with a stick welder because our welder was a no show. Second was actually trying to fix this loader. Just ran tyne normal functions and when the curl got extended out as far as it could go the weld broke instantly

I know the welding wasn't yours. You said your dad did it.
