TIG and 309L ?

I'm rebuilding a damaged tractor attachment used for moving those
round hay bales . The highest stresses are on the round "spike" that
pierces the bale . That's part of the failed structure , and I'm
wondering if it would be a good idea to use the TIG welder and some 309L
to weld this to the framework . Everything is mild steel , and will be
welded with either 6013 or 7018 . I noticed that (before the last damage
occurred) the spike had been repaired before from metal fatigue breakage
. This is why I wondered if a SS weld might hold up better in that
location . A set of small triangular reinforcements will also be
considered to spread the stress out over a larger area ... but I don't
want to get into a situation of chasing stress breakages on this thing -
I'm already beefing up the failed mount area by going from 3/8" to 1/2"
plate ... The problem is that these hillbillies are always coming up
with new ways to break shit . So us repair types gotta keep coming up
with new ways to stop them !

My experience with welding steel with stainless rod is that the
stainless tends to absorb carbon from the parent metal and sometimes
gets awful hard. I had a welder friend weld up a crack in a cast iron
engine head and the weld beads were so hard that it took the end off a
high speed end mill. Ultimately I had to reface the head with a
surface grinder.

"No" to welding the spear to the mounting -- if like any we've got
had/ever seen it (the spear) should be threaded on the rear in a near
friction-fit housing. They're hardened and never even tried to weld the
spear itself--can't think you'll have much luck there.
If you weld it to the frame then really stuck (so to speak :) ) about
just replacing it...
Unless, of course, this is a smaller unit for the little round bales
instead of the large ones and is from Northern Tool or HF or somesuch
instead of a "real" equipment supplier in which case may as well just
build a new one on top of the existing mounting brackets, probably...

Start with rebuilding it with replacement sleeve/spears...they're
readily available and not particularly expensive.

Definitely run rod. DCEP weld if possible, 6010 would be OK, but 7018
is stronger (if you are breaking the weld this could be important)
7018 is easier to run than 6010/6011 too and is low hydrogen - so less
chance of a brittle weld (if the rod was properly stored, anyway)

that mounts to the bucket mount points . That spear is not hardened
steel but I don't know what it is . It's being stuck together with the
7018 I have on hand . If I run out I'll buy more ... I started with some
6013 , beads looked like crap . The 7018 looks better , but not much .
Some days I wish I had a 300 amp MIG machine ... others I wish I had a
new Harley . Chances of either happenin' is about even . Somewhere
between zip and zero .

for the stinger and just weld the end of the stinger to the end of the
socket, with the DOM tube supporting it with no HAZ in the stressed
area????. Gusset the DOM tube any way you can - with no weld heat
compromising the stinger??

and 4 feet "long" . Just a guesstimate from my hay haulin' days of youth
I'd say the weight is well under a thousand pounds . That spear is 2" in
diameter and will be welded at the butt and again at 3" , and there will
be gussets . I'm using a Lincoln Tombstone 225 amp AC welder , but have
a baby MIG too - it just ain't got the ass for 1/2" plate . Got a 250
amp TIG welder too , but that ain't happening . By the time I finish
this I may even be able to make a bead that doesn't look like a string
of pigeon droppings . I've never been all that good with stick ,
probably because I do it so seldom .

That should be "stout enough" for those, then... ours are 6' D and a
5'W; grass weight about 12-1300 while silage can be 2000 or a little
more. It's losing one of them in the air I worry over; even tho the
only time I ever actually broke a spear was while "gathering up" and
found a gopher hole and one snapped clean right at the base of the socket.
I've seen guys get in a hurry and catch a point in the ground or try to
move something other than hay that's too heavy and bend one a
little...then they never last long after straighten having once been
strained that way...

I have a good welding inductor in the cupboard in my garage that
I've had for years - came with the aircraft generator I used as the
motor on my electic Fiat "Electra-Mobile" (to use the generator as a
welder) Too bad the darn thing's so heavy - shipping it would cost
more than it's worth.

Similar here, but what I'd really like is my old 97FLHT back or a 350P pulse

Do you have 3ph power available anywhere you can weld?
