@MrShakesFist i fukn recon
@MrShakesFist In America, they spell it and pronounce it differently.
Did you say AL-UM-IN-UM?
That is not right.
“AL-UM-IN-I-UM”
Is that too difficult?
good info on your vid. but tig is not so easy. mig is easy. practice makes perfect. most peoples problem is they dont know what gas to use… argon or helium mix? helium mix sems to work best for aluminum, pure argon for most everything else.
Good info on TIG. Search brazilwelds to see tig through the lens. good series of vids and info.
Very usefull!
sir,cn i ask what are the BLUE PRINT? thank`s im new in weldeng i want to know more about weldeng thank` a lot and more power!!!
lol easy you say huh
you have sharp end for stainlesss, black steel, steel and almost every metals exept light metals like titanium aluminum and metals like that you will have ball end and AC current not DC
Nuke-you-ler?
@OfForceAndChaos not quite the rule but close i guess with MIG if youre getting a lot of buckshots or feel the wire kinda pushin you away then you have too much wire if you see the wire meltin all to heck as soon as it comes out of the nozzle then u have either too much heat or not enough wire MY basic settin is a 28-30.5 at about a 2 and a half on the feeder but thats just me and not every machine is the same
Buenos Dias, Aqui les dejo una pagina donde encontraran información como libros, manuales, etc. todo para el amante de los fierros y la soldadura (PROFESIONALES SOLDADORES). A precios muy comodos, pero de un gran valor el contenido.
Pueden descargarlo como tambien pedirlo en libro físico. Aqui les dejo el link juntenlo todo:

you don’t essentially have to go to school, but the school will probably have an intern/extern program that helps.
or you can apply for any number of jobs at a manufacturing plant. and keep as close of an eye on the welders as you can.
just a thought. also if you know any welders that helps too.
i averaged a score of 96 on all my MIG weld tests and a 98 in TIG welding. My adviser is giving my a internship for being the top welder in my class, thanks for the tip about MIG it helped me when practicing for my tests. if i get hired on the spot in my internship my teacher said that i will automatically get my diploma
General rule of thumb for MIG (and I’m sure you’ve heard it before) If you’ve got your dials set right, your weld should sound like “sizzling bacon” If you don’t know what that sounds like, get cookin’.
It is! You need a bit more coordination though, seeing as you have a pedal controlling how much amperage you’re sending through the tungsten – usually you set your TIG welder so that you can just give’er and push right down on the pedal and just start feeding your filler rod into the puddle. I’m 19 and I’m already better than most of my high school teachers.
Is TIG welding similar to soldering?
you dont want to mate when tigging alloy you want a ball end i had the same problem then i got put threw nvq1 ages ago and i asked the bloke and he said a sharp point for every metal BUT alloy hope this helps
Mig welder is quite easy to use, the only hard part of the mig is getting all the settings right. A mig has a wire that shoots out at a certain temperature. I havent had as much experience with a tig welder but I’d imagine that it would be easy after some expirience.
I’m currently in school now and my adviser wants me to test early for my last brazing lap weld test, so i can start mig, i have experience in mig welding but i was wondering if there is a easy rule to determine to correct setting like the rule of thumb for stick
you need to be ICAR certified for automotive work
don’t use shitty ass pure tungstin
how can i do welding as a career…do i have to go to school….
Balling happens on pure tungsten electrodes when welding in AC (like for aluminum).
On a higher end, inverter based TIG welder you can adjust the wave form in such a way that you are mostly putting energy into the material (electrode negative) vs.into tungsten. So the tungesten stays cooler – and doesn’t melt. See Miller’s dynasty series fore example
how do I stop the tungstin from balling when doing alloy ?
YOU NEED A NEW TIG WELDER!!!!!!!
You need an argon/helium mix 75/25%….. use green, brown, or orange tungsten(personal preference is orange, then brown) if you use orange tungsten you will have to ball it up with dc+ for best results. I like to use a size 5 lava cup or larger.. prefer 8. 1/16″up to 80amp.. 3/32 up to 130amp… 1/8″ around 200… green tungsten doesn’t hold up to the heat so well…. so 200+amp green needs 5/32″… Make sure to clean your aluminum w/ a scraper/grinder/stainless brush and with acetone..

if you’re working thicker material, you can also MIG weld aluminum, it work very well. Some years back, I worked at a youth detention center, and we made beds from aluminum piping and sheet aluminum, to put the matresses un. Expensive? Yes, but it did not rust from water and urine. Don’t ask. jp
you are very very wrong you can dc weld aluminium the but you have to polish it up very well because there in no cleaning action and it will only really work on thinker bits of aluminium and requires alot more heat then you would use on ac but some of the postives is that it gives awsome peno …
u cant dc aluminium. and u cant get rid of the oxidisation . u can polish it to get the shiny look.
the evil sounds arcs make
Its because its AC welding. you are probably using DC.
Clean your aluminum . Deoxiding your surface will help with the shiney look . Getting rid of the gray ashy look .
im new to tig welding, but whats that evil sound the arc is making?
I wana know what kinda lense that is you are useing to cover the camera with????????????
What’s your gas mix and what kind of tungsten do you prefer? Thanks and keep posting more TIG stuff!
keep your work clean and your filler metal cleaner! dedicate a brand new ss wire brus to aluminum and wrap the bristles with foil when storing it. your are way too hot and dirty. turn the amperage down on the background and shorten the hot phase timing
very nice uniform .
beautiful weld on aluminium
Perfect!!
sexy weld man, looks nice!
That is gorgeous work..
I’m trying to get into aluminum in order to build a movie prop which requires the “dime stack” look just like what you just did. I have no idea yet why its not working. I have a nasty gray ashy skin on my passes. I’m welding 0.063 aluminum and I’ve tried on cleaned/brushed surface and non brushed surface. Argon gas, and AC setting. Tried pulse on and off, frequency 100 to 120 Hz. Still trying to find the problem..
Do you have it set to pulse, or are you just leaning on the pedal?
Too cold, too much distance between weld ripples and he shouldn’t have stopped halfway through. At least he chased the heat out to the end of the job though, to avoid the inevitable cracking.
Aluminium welding is on AC.
I ran outta rod half way through …….LO(L
i dont think this guy needs any advice like that it obviously isnt a structal peice so im pretty sure his just making it look pretty
Not bad!
Try to keep your dips a little closer together – but not bad at all!
i can do the same weld the only problem is that i m ilegal in this country and is hard to find a welder job now
