All good concerns about the welding TJ. I'm a still 'novice' welder, using fluxcore, but I was welding some joints yesterday, and man, what improvement over when I first started out last spring. you using mig?
I now get the penetration I want, and know the settings by feel now , so I no longer worry about poor or weak joints...but , they still aren't real 'pretty' without a lot of sanding and filing, ya know?
Your welds actually are looking great with the finishing you did. I don't know maybe just a little hand sanding with fine paper may be all you need..but I agree, taking them down 'too far' it does weaken the joint. Globbing on more weld- Ive done that, it just creates more work that isn't 'fun' work. lol It's sortof like getting a decent smooth bondo joint, and then starting over with another heap of bondo.
I too would be leary of adding more heat...it's bound to pull something out of alignment..especially on all of those little 'bridge' joints on that beautiful frame.
I like what PhilTmonx said above about the aluminum filler...I was going to try that on some bars that I welded together, but decided to just let the bars go a little crusty rusty on that build.
I saw one post of someone smoothing out JB weld with some water and his finger..looked to make a super smooth joint...and you wouldn't have to go real thick...Maybe try a little clear on just one of your sanded joints..clear over JB weld, and clear on aluminum putty on a joint underneath or on the bottom somewhere not that visible see what looks best...
I hear you, it's probably pretty tempting to paint it...but that is just such a sweepingly beautiful frame..I know my mind can't picture it anything other than bare steel either....
I know exactly what you're saying about the welds not looking "pretty" without some sanding and filing. Thanks for the compliment on finishing off the welds but, there's lots of room for improvement in my opinion.
I'm using a MIG welder with an argon / carbon gas mix. I've used fluxcore on past projects. Especially for areas where I was welding together some thicker pieces. The difference between using gas for shielding verses fluxcore is pretty dramatic in the way the welds look. I've been able to get a far better looking weld using gas.
Once there's no deadline and, before finishing off this frame, I think I'll run a few tests. Weld up a few samples and smooth the connections with solder, jbweld and aluminum filler for a direct comparison. Will give me a solid understanding of what it's like to work with each and what the final results look like.
