Volvo-Champion welded ball stud ?

Welder Dave said: 7018-1 has better low temp. impact values than standard 7018. I think the minimum requirement for 7018-1 is 20ft./lbs. at -40*. Std. 7018 is 20ft./lbs. at -20F. Something like 8018(C3) with 1% nickel would be a good choice as well with min. 20ft./lbs. at -40*. Click to expand... Thanks I was not aware of the -1 rating differently for cold weather. I have a bunch of 8018 but not sure if it’s C3 or what. Most of it is 3/32 tho.

The first go around my helper got hot rolled steel TGP pin instead of 4140 like I asked for. So it’s not a surprise to me it failed. That’s basically all we have available here.

I went ahead with some more fab time and made a double shear mount plate and 4140 pin assembly to get rid of the problem forever. Wish I got more time to fab stuff I actually enjoy the work.

It had a crack in there that had been working for a long time, I’m guessing when city of Anchorage broke the moldboard (there’s a big weld in the middle)

Esab Atom Arc 8018 is actually 8018C3. It just says 8018 but the specs. say 8018C3. I haven't seen any 8018 that isn't 8018C3. Fabricating stuff and fixing stuff yourself can be very rewarding. It looks like you welded the mount with 6010/6011? Should be fine. If it was done with an xx18 rod it shouldn't be whipped because it can get slag inclusions. Can't tell exactly what happened with articulation cylinder. Did the mount rip off that the cylinder attaches to?

Yes I had decided to burn it on there 3 passes with 6010, I was running short on time. if it works out I will cap it with 7018 later. I’ve had really good luck with 6010 on thick material like 1” or more. Yeah these hiem joint style bearing setups are pretty fragile. Once they get a little worn they destroy the bearing / race in short order the busted pieces fall out and then there’s 1.5” of play in the joint instead of 1/8” like a worn bushing. Pretty sorry setup really.
