Bobs 2024 Build Off Build

Kinda hard to read the weld after you grind it. It looks like the weld is just sitting on top with little penetration to the metal. Can you show a back side of the weld? You should be able to see the bluing.

how's the new helmet?

Those larger joints where the heat has time to "move in" look better than the spots. I have basically the same machine. I would slow the feed and raise the zap.

Lets see yer work B4 ya grind it. Ya should be able to see the blue heat signature on the back as stated above.

I think that the wire feed control also has some effect on amperage too. More feed more amps. Less feed less amps.
I also think that thickness of metal is the limit of that welders capability. It just can't heat the metal well enough.

Try a destructive test. Make a 90 weld and then set it on the ground like a tee pee. Then BFH the top making the legs split.

Keep at it bobO.

I think I have some photos before grinding.
Here was one of them.

Tried to photo the backside.
Theres a few tacks “inside” the tube, on the back side of a couple of the beads.

Wonder if I should try without this anti-spatter?
I’ve been welding through it. Mostly water I think. Maybe it drips into the weld?

The guy who I know that put the steering head on said he was only familiar with ceramic sprays with cannot be welded through. He started covering the area he wanted to weld and was surprised when I told him you should be able to weld right through it.

Maybe with such low voltage / amperage the anti-spatter coating causes issues?

I think that get sprayed on the nozzle not the work. To keep the spatter from funking up the tip.

Ya but it also works to keep spatter bb’s from sticking to the work. I did micro GAB and watched some of this video of a dude testing 47 anti spatter products.

 

[bob58o]

In my mind. The water in the spray absorbs the heat as it evaporates reducing the amount of heat going into the work…

No idea if this is significant or not, but worth testing IMO.

Wow! 200# of packing materials!

I was implying that I will need two pounds of welds to hold the 200lb bike together. lol

 

[Master Hack]

First look i saw a huge wooden crate.....
Don't be so negative, you could very well use more, B4 yer done!

Spatter sticks to my titanium wedding ring like bonkers. I have to sand them little things off there.

That is a major safety violation! Where are yer gloves?

Bob if you finish it this year you just may win the build off.

That seems like excessive spatter, is that a characteristic of flux welding or an indication of sumpthin wrong?
I don't flux weld, i'm curious.

Flux core is known for spatter. I guess.
I only know this machine.

It a mig with out the gas. So it's like a stick, it has flux in the wire.
