weld that baby up

 

[scf84]

could it be welded on the outside or need to seperate the bar and weld inside?

If you have access to a TIG welder and can use it by all means weld it on the outside. It is a heck of a job to separate the halves. If not proficient with TIG welding then find someone that is. Regular arc welding will blow a hole in pretty quick because the metal is thinned out by wear.

I have mig welded them, as well as stick. Some big gun will tell you other wise, but I'd turn it upside down, and use a 6011 rod. You can see your puddle with a 6011, and have a decent idea if your fixing to blow through.

i hit a old post on theg roudn with mine a couple weeks ago and bent the blade at 90 degrees.. it cut a huge hole in my cutter bar. I couldn't believe it.

I welded it with a stick welder and she's like brand new again

Tap around it with a small ball peen hammer to tell if the leaking area is thin. If it's not, put a root in with 6010 or 6011 and cap it with 7018. The 7018 is harder and will not wear off as fast as a 60 series rod and if you show three beads, the two outside ones will protect the one that actually sealed the crack. If a crack has developed, be sure to drill each end of the crack with a 1/8" bit before welding. Weld over the drill holes. The holes will keep it from cracking further after the repair is done. Have a water hose or fire extinguisher handy. Oil can burn. I would also do it outside.

You schooled me on drilling a hole at the end of crack. Thanks. That's going in my mental folder.
