Check my welds

admin

ok dont be real harsh lol. I know i need better puddle control but i just picked this tig up a week ago and read up on cleaning and tungstons. This is .063 aluminum ic piping done with 3/32 red, 3/32 filler. This is my very first piece of aluminum piping ive only been running beeds on flat stock. Also wondering if i should go back over it and make the welds wider? Will it hold lol?
Reply:Red tungsten is thoriated. Switch to green, pure tungsten. I see a potential pin hole in the first pic you may want to fix. Nice clean up job. I don't see any indication of you dipping the tungsten, thats good. Could have gone a little slower in the first pic. Will it hold? I have no idea. Whats it for?

Reply:hook it up to test it and run the system. i agree with Grimm - you have a problem with the pinhole. i would for sure re-work some of it but probably dont need any filler rod.not bad at all for just picking it up.my favourite thing about tig is that you can rework the weld. id also turn up your amps a little more. the guy that helps me tig always tells people the same thing - go get a piece of scrap aluminum or SS and cut it into 1-2" pieces - weld the whole thing together and by the time youve got a foot or so you should have it down for a good sturdy weld. might not be pretty but you should have the hang of it by thenI break things for a living...
Reply:heck youre doin ok for just picking it up..................just keep practicing its all in keeping the angle of the dangle in direct proportion to the heat of the meat

Reply:I think I have heard about some inverters having trouble with pure (green) tungsten. You could look into some of the other tungsten alloys. I think lanthinated tungsten may be the one you want. I'm used to the old transformer rectifier welders, pure tungsten is the way to go with those.
Reply:Orange or gold for aluminum with an inverter.  Green can be substituted in a transformer machine if you're desperate, but red isn't real good for AC use.Hobart Stickmate LX AC/DC, Millermatic 252 & 30A spoolgun, Thermal Arc 185 TIG, Miller BWESmith Oxy-AcBridgeport 2J , South Bend 42" 9AHusky 7.5 HP 22.3 CFM 80 gal compressor

Reply:You really need to be using 1/16 filler material on tube that thin.  As a rule of thumb, your filler should never be heavier than the material you're welding on.
