My main concern is not to have a weld competition with the rest of the world, It's making sure things don't break and perform the task as to which they were intended. All visible gusset pics above were intentionally "rainbowed" on a second pass for visual flair if you will,since 90% of anyone buying a welded titanium anything expects to get something pretty,lightweight and functional.All actual tube joints are silver to spec.The reflective nature of the gusset welds against the dull background make photographing it a pain and really don't do it justice.I'll surface condition the next one just to prove a point, and since I'm officially irritated... Oh yeah, here's a pic of a Ti dragster jack handle that I welded that's been surface conditioned

Yeah,that's this post being written in the background. Any questions?
To save myself the time of answering any conceivable questions regarding why I chose not to surface condition these, the answer is that they don't fit in the tumbler I have access to, and after investing a couple days in making a vessel to weld these in any extra time/costs added to the already preposterous venture of a run of any specialty produced piece being a one man operation- deterred me from taking it any further than what was necessary. We good with the whole welding bit now? Great.
you are still convinced those are top notch welds. amazing.

guys down here at NASA weld on things like shuttle parts, and they are absolutely perfect. welds like the bike a few posts up are done at that level hand held all day long. it does not require a robot. send us the radiography from your welds.
