Yes SS, as a matter of fact they were. Does that means all BMW bikes are gonna need to be recalled??????
And Carl, when did you "review" the welds?
I know you weren't here in the Mojave desert at my shop when I took these pictures, because my perimeter fence mounted bullshit detectors never went off.
And no, I did not do these welds, I am repairing centerstand mounts, WITH A MIG WELDER.

Nothing wrong with Mig for a technique.

I would be proud of those welds if I did them, but I expect everyone else to be better than me.

Hey Super can you point out which one youre referring to? I'd like to see the cold weld.

I think the shaft man was referring to the bead in the bottom of this picture which appears to have been a bit on the cold side. See how the bead appears to be sitting on top of the tube rather than melted into it? Not perfect, but also not horrible. Penetration could be better though. I haven't picked up a TIG torch in near ten years so I can't really say anything too bad about it.

The green primered frame with the HPN brace welded to it. The bottom weld. See how the bead is piled up on the frame and doesn't flow into the frame. The factory weld right beside it does the same thing to a lesser degree. That is a classic indicator of a cold weld. The other side of the weld wasn't cold but it is easy to get a thin sharp edge of sheet metal hot. A good welder should know going into that weld that the majority of heat is going to have to go into the frame for it wicking all the heat away. Good welding IMO is mostly about knowing where all the heat is going. You become very aware of this phenomenon welding the last couple of tubes onto a multi-jointed intersection of a fuselage. Welding aluminum will school you real quick on heat sinking too! That stuff just SUCKS the heat up!

I wouldn't call it horrible but it isn't good either. I sure wouldn't want a picture of it floating around on the internet!

Thanks guys!

Oh no, the straw dudes from the blizzard of oz are posting again....

For your reading pleasure.

Rather than waste time replying to the twisting and distortiong that was done on my brief posts, it is time for a test comparison of the welds in the pic versus the HPN (or similarily done) welds. Are straw dudes game for a bet?

Cheers,
Carl

p.s. Straw dudes, are you building any gems like these:

I'm not sure who the straw dudes are, or even what that means, but if you're referring to me, then yes as a matter of fact my frame is at HPN right now.

Does HPN double up on those swingarm pivot plates?

No reference to you as a straw dude.

Also, most everyone on this airhead forum probably already knows that you have a frame at HPN.
