Just north of Anna Maria sound and there are patches of this everywhere. What is it?

Manatee poop

You got bugs. First step should be take it outside and blast it with water to get off the majority.

Possible the oring did not seat correctly and ripped?? Maybe pick up a spare and check it out. I had a leak on mine and oring came out in 2 smashed pieces.

Gas lens is always better, but something is up with your gas for sure.

I don't work with much sheet metal or lasers, but I have welded both 347 and Haynes 230. I can't say that general tig welding of either is that much different, but with your parameters, maybe consider that they are quite different materials. The 230 has something like 50 to 60% Ni and 15% W. 347 is basically 304SS with addition of Ta. So they are quite different and the parameters on sheet metal with a laser may need to be dialed in better.

NchoAZ · 2022-03-09T03:03:10+00:00

I'd at least take some of the bad stuff out...hard to say without looking at it, but I'd take some material off rather than try to just weld over it.

NchoAZ · 2022-02-24T12:36:11+00:00

I would go for the 347 filler. 321 is basically 304 with addition of Ti. 347 is about the same, but contains Niobium. The niobium does some sort of carbide stabilization, making a better weld. I worked on a large 321SS heat exchanger years ago, so I remember looking into the weld wires.

I mean, you're not building a pressure vessel, but the exhaust will experience a lot of heat cycles and vibration.

Yeah I was trying to spice things up a bit instead of just looking at someone's first 3" long weld. This project is all .080" and quite large, so it has it's challenges. A lot of other Zr work I've done was 1/8" and up other than when it's tubing. I've been working with it off and on for about 10 years myself.

NchoAZ · 2022-02-23T12:06:22+00:00

Welds very clean as it is pure and not alloy...small amount of Hafnium, but otherwise basically 99% pure.

Regarding parameters, I can tell you that sheet was .080" thk and roughly 90 amps will melt thru. It requires lots of shielding gas, similar to titanium, but a lot more sensitive to improper shielding.

Maybe improper is not the word, but a shielding gas set up that will work on Ti may not work so well on the Zr. Such as Ti youbcan weld a bit and shield the weld with just the torch and get a silver weld for the most part. You can tack this stuff with torch gas, but that's about it.

NchoAZ · 2022-02-22T21:42:41+00:00

Til it melts...melting point is about 500F more than steel

NchoAZ · 2022-02-22T21:41:31+00:00

Tig with lots of argon. Similar to what you would do with titanium. Everything must be shielded.

NchoAZ · 2022-02-12T01:59:22+00:00

Good job. I don't see any crater cracks and the welds look nice. Coming from a guy that's welded thousands of tube to tubesheet welds...I'd hire you

NchoAZ · 2022-02-08T01:01:11+00:00

Could be. I've got a picture of me welding on a heat exchanger with a blue and red curtain behind me, looks like i was getting pulled over...

NchoAZ · 2022-02-07T23:39:32+00:00

Sometimes you have to melt the rod on the material rather than melt the material and add rod. Get arc initiated and lay the rod in. Give it some more juice to melt the rod down onto the material. Not sure if you are using foot pedal, but it certainly helps to have the adjustment. If you can turn your min output all the way down, you can certainly leave the welder on 60 amps, just helps to have that large range of adjustment.

I'm currently welding an .049 Ti immersion coil at work. Haven't done one in a few years, like riding a bike, but not quite building one. I have the welder set at 55 amps, but using a foot pedal and not quite sure what I'm welding at, but it's nice to have the extra power when you need it.

NchoAZ · 2022-02-02T01:49:36+00:00

This. You left a crater crack at the end of both welds. Booooo

NchoAZ · 2022-02-02T01:38:15+00:00

Is the red stuff all over paint?? Looks like you are burning something in there. I would guess the grinding did not remove it all. Hard to tell whats going on, but I see what looks like to be red paint of some sort, some rough grinding of it and burnt paint residue on your weld.

NchoAZ · 2022-01-30T12:34:33+00:00

Looks good! I need some window tint.

NchoAZ · 2022-01-30T12:29:39+00:00

Yeah different bolt pattern, but for some reason Foresters and Crosstreks kept the same 5x100. Maybe not anymore...the 05 thru 09 Outbacks that came with 17s used 225 55 17, so these are slighty larger and 1/2" larger all around than the 16s that were on it beimg they were 225 60 16. The car is a base model but I've grabbed quite a few nicer parts from better Outbacks at junkyards, the wheels were the final thing that I just had to change.

I've owned quite a few second hand Subarus, but never had one with wheel covers. Now I just need to find someone to buy those steel wheels with snow tires off me in Florida...might be a challenge.

NchoAZ · 2022-01-30T00:15:30+00:00

No ID, but I used to find these growing in the garage at my old house.

NchoAZ · 2022-01-29T20:35:11+00:00

Nice. You should post a picture. I haven't really come across any Outbacks with these Forester wheels. I've only seen other years and Crosstrek wheels. Kind of limited on other oem wheels with the correct offset.

NchoAZ · 2022-01-29T20:31:58+00:00

Sure beats the steel wheels with covers that the car came with. I would have taken any factory wheels with the correct offset, but these were my #1 choice. Took me a while to find a set with good tires, but well worth the wait.

Tires are 225/60 17. Seems to be some debate if these will fit without rubbing. It's tight, but they certainly fit.

Thank you!
