Not bad BigD. We were going to to get some titanium donated to the school by a local business but we still don't have a 300 amp torch and we were concerned about ventilation. So: How many amps did you use? Did you feel sick afterwards breathing it in? I had peak set to 90 but I didn't use full jam ...

Still waiting on the 4943 so I just refilled it with 4043

Got my titanium sampler kit from Ticon industries and gave it a shot. I'm an instant fan. Was nervous at first but it actually went quite well once I got comfortable. I used high speed DC pulse, made it quite easy. Welded 3/4-1" at a time letting it cool, with a Furick 12 and 20-25cfh. It's def...

Yeah, I got a hold of an aluminum expert from a very respectable company but I've been waiting for his express permission before I share his words verbatim. But to paraphrase, he said it takes hundreds and possibly thousands of hours of exposure to stress in a corrosive environment and high heat bef...

A friend of mine is building a pit cart and asked me to help weld it up as his welder wasn't up to the job. The frame is 1/4" aluminum which is normally no problem for my Dynasty 210. This was quite the pain. I didn't anticipate how much effect the size of the heatsink would be. He brought it t...

That's what I'm going to try next, sounds like the magic bullet - nice properties of 4043 and strength closer to 5356.

This may be interesting . http://www.esabna.com/us/en/education/blog/the-most-suitable-filler-alloy-for-6061-t6-component-operating-at-250-deg-f.cfm Also there was a thread on here a while back on the welding of AN fittings. That was mine too :) At least I'm finding out about these things before th...

Yep, definitely the right way to go. I'm one of those guys that doesn't sleep at night knowing I didn't do something right, so it will be redone.

The reason I ask about a cover pass with 4043 is that according to what I've been reading, it's the magnesium deposits that are problematic when exposed to corrosion under stress. Furthermore, one paper I found showed that the failures in the study were limited almost exclusively to 7% content metal...

Having a bit of success finding more technical articles incl research papers. The corrosion bit seems important. Eg weld in a boat hull with exhaust running along the weld.

Just to clarify, I'm not looking to find out whether or not it's ok to use the rad, I always play it on the safe side when I don't know so I'm going to toss it. I just want to learn. Also, I have some bungs welded on which I'm not sure which rod I used, can I just go over the welds with 4043 or cut ...

I understand they didn't make it up but I'm looking for specific metrics. Stress is not a measurement. 1 bar +- is certainly stress, so is a gentle touch, neither is a big deal to 1/8" aluminum normally. According to the metallurgists, some level is to 5356 above 150F... I would think what that...

I've seen all of those but none of them define what they mean by corrosion stress cracking. What stress? Suspension component or a fluid container? I really doubt that boiling any joint of 5356 in water and holding it there a while, then gently pushing on it will make it crack - that's corrosion and...

So my go-to rod for aluminum lately has been 5356 because I find the welds look nicer and it has higher strength than 4043. I recently built radiator end tanks for my old rad for fun and I happened to come across a 5356 spec sheet and saw that over 150F it is susceptible to corrosion stress cracking...

Other than appearing slightly larger than the 17, the 20 is water cooled That doesn't sound right, the 20 should not be larger than the 17. My CK 20 is a hair larger than the Weldcraft 9 (the middle rubber cylinder is a tiny bit larger in diameter, I guess to accommodate the waterflow, but it also ...

Thank you guys, means a lot coming from you!

Finished product, well just need a drain petcock

I think it depends on what you weld. If you're usually welding on a workbench with clamps and fresh metal, you don't necessarily need to keep the MIG. Beyond being faster, the main advantage of MIG for me is simplicity. When I have to tack something in when badly out of position in the car, like rol...

Part of my AN plumbing conversion project will be a nice custom PWR core so I don't need my stock one anymore. I'd always wanted to try building a radiator out of a core, for myself and as a service to offer. Ripped out the plastic end tanks and started making my own using some 1/8" plate and h...

I want to learn to weld titanium so I started playing with building a purge setup. Bought some 063 copper to build a little purge box. Never welded copper before, got some 14 gauge romex as filler but I actually found if I pulsed the pedal while moving quickly, I had better luck using no filler at a...

Just wanted to show the finished product finally installed. It was to hold up my end of the bargain where I got to claim the other side of the garage as a workshop if I could provide a way for my wife to park the truck under the hoist in the winter. Needed to get the racecar higher up and the rear a...

Yeah, implied respect is a dangerous thing when it comes to technical knowledge and ability. It's one thing to be nice to grampa over his bigotries he expresses at Thanksgiving dinner but having to respect someone's opinion with regards to something scientific, just because they've held it for a lon...

I've got a 1000hp one myself Where do you run that? Still testing it on smaller local tracks. I designed it for time attack at the big tracks, specifically my 2nd home, Mosport. But I've been finding various issues to work on and have endless scope creep. This winter I was just going to put in a cu...

Got the independent AC expansion for the Dynasty and played around with it today. In short, my findings were the same as Zank. The recommended Miller settings didn't do anything for me except cook the tungsten because decreasing the EP makes you have to jack the EP balance. But doing 50% more EP all...
