A friend has a rudder made of silicon bronze that some cavitation (the propeller pushes water away faster than it can full in, creating vacuum, which creates basically what I understand as steam bubble that eat away at the metal) erosion that he wants filled in. What rod and what setup would I use t...

Sent from my Commodore 64???

Is that a joke?

On my everlast machine, I can set the machine to limit the top amperage that the peddle can reach. To me, it seems that the lower I set this top amperage the more control I get at low amps, Just make sure the top amperage is high enough to do the job.

I have used a piece of paper several times wit good results. Marking the cut is only half the problem, making the cut is the other. I know hand tools are not the fastest, but, accuracy not speed is the main goal here so I would use a hand hacksaw. Block it up on several saw horses so it doesn't roll...

sorry posted the above on wrong page

Thanks for the input. Being able to weld them to the yank will enable me to keep things tighter to the and and space is very tight.

wire is clean

I have done a few more and It seem to have stopped. I cleaned the weld table maybe I was pickng up something from the table

Nice job
doing those kinds of repairs just ups your skill set for repairing a part you can't buy

Just started tig last year with an entry level DC machine Everlast 160 STH. Nothing fancy Post flow, Lift and HF start. I have added a peddle and a CK torch.

Correction on fist time back purge

torch had 20 cfh

I better proof read more

Mark

first time back purge Finally got set up to do back purging. The results amazed me. Even though it looks like I need more flow on the purging the sugaring disappeared. The joint welded easer, flowed better and much cooler. I have a hard time getting any color but grey on my stainless welds so the co...

Not quite razor blades but both tubes have a .025 wall thickness Square tube about 11mm outside dimention

Just did another one. Switched to .040 tungsten and a #6 cup and it went better. I could not see any difference in prep but almost no sparkles and flowed better. First tries 1/16 tungsten and #8 cup since I keep reading that with a sharp point one of the larger tungsten will work well thin stock. I ...

Thanks I didn't think it should. I guess I will have to try cleaning better or just try a different material

I my quest to get better at welding thin material I tend to forage through old junk. Today I have been working with some small square steel tube from a desk lamp. About 10mm x10mm by .025 inch hall thickness. It welds but no mater how well I clean it, I still get sparkles as if mill scale is still t...

Yes an everlast 160 HTS

I have been tig welding for about a year now, have made several posts and am getting better. Still have a lot to learn to be at the level of many of the members

Hi from Mark in New York City I have been on the forum for about a year and have loved it. I am an old dog trying to learn new tricks. I have always enjoyed building thing and now since I retired in 2013 from a maritime job, I have the time to try and add the fine art of tig welding to my skill set....

It's more of a general interest question.

I have nothing at this time that I am worried about, but, with my general skill level it might pop up

Thanks for your help The epri web page gives interesting reading and I hope the last paragraph gives me at least hope, that the contamination does not go through the entire weld and can be dressed down. I am still new to TIG welding but I am improving just not there yet. Hopefully soon these concern...
