What happened to the cut out? Ali express?

I edited the picture but the damage was done.

Oh shit. Prolly is On-Here?

Lulz

Nope, I am one of those weirdos who thinks aluminium welds should be done neatly and accurately in the first place, others manage it.

prolly isn't user amey?

If Prolly has moved to Catford then yes

Catford is the new Santa Fe

Thanks for clarifying - got an example? I'm really not seeing the issue with the Rock Lobster welds, and I'm curious.

They're OK, but they're not going to #stackofdimes likes on insta

Paul doesn’t seem to be a person prioritising form over function. He has been welding long enough to make clean welds but that isn’t why he churns out frames. Utilitarian - and some people find that a quality to aspire to and ipso fatso pornworthy. Different strokes etc etc

ipso fatso

I will find a reason to use this malapropism, and it will probably involve @hippy 🙂

it's so fatso is how mum greets me at xmas.

Good aluminium welding yes?

Bad alu welding yes?

That was the beauty of C’dale right? You couldn’t tell until they cracked…

Were they (Cannondale and Klein) doing welds accurately and neatly in the first place or do they just file/grind them down? GT's high end alloy bikes in the 90s had rough looking welds, but I recall reading that this was done purposefully.

Strength innit. Those neat bulging beads are way stronger than the filed C'dale above it.

Some of that C'dale tubeset will be paper thin through filing.

They didn't file the welds, in the old days they did a double pass weld, which results in the smooth look.

Internet Quote -

Most like Klien, Cannondale use a handheld belt sander to do this and will use different grade of belt to clean them up. However they use a form of welding where they will build up multiple layer of weld before they smooth them out. If you do this to your GT you severely weaken the welds and this is not recommended.

What about rainbow coloured welds on titanium?

I'm sure some people who can't weld have something to say about those.

Discoloration on ti welds is objectively bad.

I... don't agree

don't agree

The colour is oxide, so the Ti must have been exposed to oxygen while hot. It's not exactly confidence inspiring that, at best, the welder was in such a rush that they pulled away the shield gas before the weld had cooled. At worst, the Ti wasn't properly gas shielded while molten, in which case the weld will be porous and not long for this world.
