Thread: What did you weld today?

Can you tell what it is now ?


When it was all done


How the S475 sat in the car, wrapped and braced to motor. Pie cut some aluminum, added 3.5" AL vband, did a flare at end of 3.0" pipe to mate up to Vband.


Downpipe, internal welding to smooth transition


Get some perception on how deep the the transition was

We use a buffer wheel on our stainless steel mig welds and it cleans the joint up super nice. Mostly we mig carbon steel, but we do a bit of stainless. A buffer wheel works great to clean both. We don't clean our stainless before welding either.

Bet that was fun to weld. Fill the tube up with argon and stretch the tungsten way out??

What kind of piping are you using?

Some old pics from an is300











Downpipe with o2 sensor bungs. Had to put two upstream and two behind the cat because the 2jzge has three cylinders as bank 1 and three as bank 2.



Intake piping.

That is some nice welding. I welded professionally for about 2 years (all day with TIG and MIG for a tubing company) and your welds look about as good as ours. You've got the touch. We found that when new guys came in, if they couldn't figure it out within a day or two, they never did. It's something you are born with a knack for (mechanically inclined) or just not going to have the touch.
Great job and you should be proud of those welds! Welding all day is a crap job, so I quit. can't believe I stayed as long as I did. It's a hot sweaty job in the summer. Plus I can't tell you how many small weld bb burns I got. Got serious "weld tan/burn" a few times.

believe it or not, I am using a 17 torch and I used the Pyrex clear cup kit from HTP, and short cap and shortened tungsten, I haven't used backpurge in a long time, when I was doing titanium work repairing exhausts. I started to use solarflux last year, but a good cleaning/ prep work and proper heat control, I've been good so far.
The vband flange is 5" from BW to some crazy sch reducer 5" to 4", used 14ga 304SS 4" bend to single 3" exhaust terminating in twin 2.5" Greddy mufflers.

looks good nismo.

i use the solar flux on all the long piping. like midpipes and downpipes.
if im doin a small pipe like j pipe i like to backpurge with argon.

usually with flanges and collectors theres no need to backpurge.

Testing with demo Miller Syncrowave 250DX AC Pulse 60-100A 18cfh argon, HTP 3/32" 1.5% zirconiated, HTP 1/16" 4043 rods, cleaned with acetone, Hitachi koki drill press, MSC 3.0" hole saw MSC 2.5" hole saw, BluePoint air saw, Merit 80Grit flapwheels 3.0", 1/0". Side piece cut from 3.0" straight section, and leveled w. Dayton belt sander.

Never been so terrified of welding, have over $1000 in wiggins clamps, and ETS end tanks/ intercooler.

i like that. super clean set up.

those clamps aint cheap at all.

i like using red tungsten for aluminum 2% thoriated. every book u read will tell u green pure. it aint that great. any good welder will tell you red. but they say there is alot of bad stuff in the red so there trying to phase it out.

i switched to these arc zone light blue hybrid tungstens for aluminum. they work great.

Arc-Zone.com :: ArcTime All Purpose Tungsten Electrode

they can be used for any type of metal but i still like other tungstens for steel and SS.

usually S.S. i use orange which is ceriated.
steel is use the good old red thoriated.
