Enrolled in a TIG class at the local JC Been in school for 3 weeks now, got some training on different techniques, some history of GTAW, learned how to sharpen our tungsten, the do's and don'ts, basic machine operation (Miller 250 Syncrowave, Lincoln 255 Square Wave, Miller Dynasty) yada yada.
Laid my first pad of beads using a #6 cup, 3/32 tungsten (2% thoriated) on 1/8" steel plate, DC-, @ 100amps.
don't forget to turn ON the Argon!
here are some lap joints I did fusion welding, this was on our first night on lap joints. we had to square the corner instead of rounding it. bottom corner bead(on the metal stack, not the picture) was the first, top corner was the last.
this was later in the week:
this is from this last week, 6061 T6 1/8" aluminum plate, 5356 filler material, pad of beads using the Miller Dynasty & 2% tungsten
I know they aren't pretty but its a start

Then I would only need $4000 for a good tig welder & gas

Moregrip, looks good man. I am by no means the more pleasing tig welder to the eye, but you just get better the more rods you burn. To me, its the most enjoyable form of welding, and as you know, the most "artistic"

I do a lot of TIG welding at work along with stick and MIG. Being that we have TIG capabilities I rarely want to go with the other processes because it's so much cleaner and so controllable. MIG is nice also depending on what job you're doing, but TIG really is the Cadillac of welding. I am currently saving so that I can have my own machine some day.

Great job by the way, not bad looking beads, aluminum is so much fun to weld.At least when it clean that is, now trying to repair a 10 year old dump truck body full of blacktop and stuff that sucks.
looking good man!i started welding 3 1/2 years ago, basically when i started my apprenticeship, and it's by far the saving grace of my job, i love doing it......and i'm with machinist, if its possible to tig it, that's what i use......learn how to walk the cup and you'll be laying down art gallery quality welds in no time.....
Shoot, I just looked into taking a course like this myself here in Cypress. To take the TIG class you have to take 2 prerequisite classes. That sucks. All the classes are in the daytime too. That sucks even worse.
Those welds look good. I have a certificate for sheet metal but took a bunch of tig classes, those welds look good. Have you welded before? I remember when i first started tig welding and my welds looked like ****.
your doing what i used to do on the laps, your running the edge of the puddle into the metal on both sides which is good, but your doing it more like a weave. try and get them a little more convex and they will run in better and a smoother. always watch the puddle. you should work on starts and stops and try more tie ins instead of only stoping once or twice. and for the people who dont want to take the prerequsite class, take it you will benifit a lot from it. most places i think its stick1/2 with learning how to cut with a oxy acetline torch. the prerequisite classes wouldnt be there for no reason.

I am a fabricator and have been for quite some time. I am new to the site so as soon as i figure how to post pics i will post some of my micro tig beads. I work with custom motorcycles and cryogenics and pretty much every thing else. I love it and once you get good at welding start getting into fabrication it pays very well and its a blast. good luck.
Make sure you are sharpening your tungsten vertically to prevent swirling of your argon keep it as sharp as a needle( unless alum ). Also if you are not running high grade argon you will start getting porosity when you near the end of your tank, trust me its not worth fighting those damn bubbles on your stops just change the tank. This is exceptionally annoying when you use a turn table. If you do get bubbles just lower your heat gradually while making small circles around the bubble. When bubble pops simply increase your heat and allow to fuse add some metal to fill if need be or if working with pressure vessel. Always make sure your electrode is as close to the weld as possible a all times. This is one of the most precision applications in fabrication but once you get the hang of it its a blast. I can walk a bead straight up into the air it looks amazing from inside the helmet. Practice makes perfect and if you an artist you will find yourself around the learning curve faster than you thought possible.

I have an awesome auto-darkening helmet and love it... makes alot of difference
With a dynasty, I run 2% thoriated for everything and run a sharpened tip on everything. Getting the ball isnt necessary with todays technology and it is really an old welders (Wives) tale
