Fully welded a top wishbone in my shiny newly built jig, after the old wishbones warped when I welded them..
Not 100% confident about the welds, would like opinions from you chaps. If you can't tell from the pics then please let me know.
I know this is a critical part on the car, tell me if I'm not up to it and I'll buy some / get them professionaly welded.
Concerned about 3 spots of aero I have noticed, and smoothness where one run ends and another starts. Penentration overall I think was good (see what
you think)
More pics + higher res if you want to see on my gallery (click here)
By the way, this is 1" OD 1.6mm wall tube for the arms, bit more studly than the book spec.
Looks ok to me! Have a look inside the tubes and see if the welds penetrated all the way through, if it has you should be fine.
Neater than my migging thats for sure

Was the gas not up high enough? Maybe marginal?
Just trying to think of reasons for the aero!
It could always be it's hot gas excaping from the now sealed tube!
HTH,

The welds look pretty good to me especilly the middle pic.
However try a little less wire and or a touch more current. This will increase the penetration and reduce the amount of surplus weld you have.
If you get the setting just right you get a spray transfer where the wire is close to melting back into the nozzle and is actually molten from the
nozzle to the work.
ditto the above, more than adequate IMHO but a little less wire would make it less raised (though in places it looks very nicely sunk in, ie good penetration)
That doesn't look like mig welding to me, more like conventional stick?!
Looks good but as mentioned previously the penetration in some areas looks slightly suspect.
good luck!

It is arc isn't it?
Certainly looks like my arc welding although seem to be a lot of people suggesting its Mig so I'm confused.
From my completely unprofessional point of view, the first picture, right hand weld looks ideal apart from the air pockets, the left side looks like
the penetration wasn't/isn't there and the weld is sitting on top. Not enough juice!
Possible the left side was the first weld?
Thanks chaps. It was MIG.. I see what you mean about the left bead in the top pic, I think it's partly illusion due to shadow and a pronouced
blob at the near end of the run where it ended.
There are more pics on my gallery - I put a link at the bottom of the original post but it's not obvious.
I'm generally reassured, think I'll keep em, now to get them heat treated.. going to try speaking nicely to a local pottery and see if they
have good temperature control on their kiln..
Look good to me, certainly better than the ones that I bought some time ago from ARA Racing and sent back because they were sh1te!
nice cutting, i must say. How was it done?
Asking me? the cutting of what?
Looks as good as anything i've migged! And heat treated? You must be serious! What exactly do you mean - this aint something i've heard
of people bothering with before...

Ah, sorry, I just mean stress relief. At the moment it's trying to twist out of the jig and I can't move the bar that lines up the
bushes.
I wasn't talking about heat hardening or trying to change the strength characteristics in any way.
like everybody else says right one looks ok apart from the porosity, need more heat on the left one but as long as its penertrated enough they may be ok unless you fancy another go, now go clean that spatter off my welding teacher wouldn't like that lol

Paper and file all the way
templates with "tubemiter.exe" that's floating about, rough cuts with hacksaw, the rest with lots of file and fit, file and fit.
