Tig Repair

[Chaz]

Yes , I called it "purging" in my post .
I also use "Solarflux - B "
The picture I posted was of the small weld I put at the top and bottom of the flange . Not an ideal place to put a rubber stopper while welding .... LOL

There are people that can weld and than there's Welders. Some one close told me that

I used 4043 on my block. It's held together now for 3 years. (knock on wood) Oh, and I used some 6061 scrap to cover the big holes. But I tried to use any large chunks of the original block. (The flange, and the fuel pump mount boss)

A rod cap bolt walked out... and in turn... the cap blew a part, and then the crank mashed what was left of the rod though the block. It beat the piss out of the back of the fuel pump, cracked the block internal... and shattered a sleeve. But, a little TIG time took care of most of it. The home oven was employed to put the new sleeve in. (boy, the wife was pissed. LOL)

I Love the '' muffin and block '' mixture. The wife ( mine at least ) would be pissed at this. Keep yours, she is a rare specimen.

Cool, went back and read it , I was just looking at the pictures and not reading, some things never change. I'm gonna break down and get a pyrex lens some day. Just welded some .020 inconel with a .040 tungsten and .020 rod amazing what you can do with the right stuff,strong glasses and no cafene.. Dave

I plan on it.

When I told her what I needed to do... she gave me a funny look. But... she did want the boat to run a gain. And if using the oven could save $4k over buying a new powerhead... she was OK with it. Her response was... "Well, let me bake my muffins, before you ruin the stove."

That is correct .. !
A welder is a machine ...
A welder is a man who welds like a machine .... See the difference ...

No caffeine ...

That's were I have to draw the line ... beside's , I thought the shakes are where all those nice beads come from ...
My purge / back gas / argon leak to the inside , is just a ball valve thru a nitrous jet ( some habits are hard to break ) then thru some tygon hose and a ACE hardware stopper (another one on the other end too ) .
I have a .040 gas lens set up . Had it for a couple of years . Just cant seem to bring myself below .062 for some reason ...

I have the same machine, inverter at work has craped out several times but the 250 keeps on tickin. Yea bought the .040 thinking probably melt/burn right off but cool looking little bead that I never thought I could do and the machine has never been on 20 amps. Dave.

I have the Synchowave 180. Originally I was looing at a small inverter, but the local dealer made me a heck of a deal on it, since it was "Last years" model. I got mine for $1k out the door, with a new bottle, rods, and a dozen tungsten tips. (a few of each kind)

On aluminum... I can get good welds... just could never make them pretty.
