i also use a kempi tig....they are top shit. Good to see that atleast someone on here knows a little about pipe purging to protect the root peno from contamination.....not many people are aware of it and why its done...good work troy.

Welding whilst sitting on a good level bench is awesome for nice welds. Try welding pipe in the 5g position. My neck and back are killing after the root run and hot pass, let alone a few capping runs.

Michael,

Have you tried a product called "solar flux" ?? it seems widely used in the US as a paste flux purge to use on the inside of pipe welds where purging the entire pipe is either not viable or will waste a large amount fo gas ..

been trying to find it here in AUS but none of my welding suppliers have got it.

no i havent chris. haha i know the theory and prac behind purging....but ive never bothered myself, not unless i was making something and it was specifically required. The closest thing ive done when doing exhaust and i/c piping is stuff rags in the ends of the sections im welding to stop air running through the inside and contaminating my weld area. I suppose thats a basic form of purging if the gas was filling the section through any root gap i left.

yeah fair enough, i have the y adapters and stuff at home, but atm the cost of GAS overrides the need for true purging ...

all the exhaust work i have dont has been section cuts for wastegates - which i die grinded after each section was welded one.. making it smooth internally

if your good enough you dont get any real peno sticking through and dont need to grind it out :thumbsup: For most piping on cars the strength isnt needed like it is in a structural job. If you can get it aligned spot on and dont get any peno it makes the job that little bit quicker and easier.

just thinking about doing that is hard lol

what filler would you use thats thin enough to melt before you blow a hole in the can?

might be a noob question but anyway. I've seen electrodes for an arc welder that are suitable for stainless steel. Is it possible to weld stainless with an arc welder?

Anyone tried it if it is possible?

Yep your lookin for 316L electrodes or better, the rule of thumb is whatever material your welding always at least match or better it.

Best you just tig it much better in every way

    • Oh, also, forgot to add these photos I believe.
    • Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !
    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
