Dubya...not George W

OK you bought a tig welder, you bought a tig welding torch, and you got some tungsten electrodes.

Now its time to get some Tig Welding Rods.

Its kind of hard to find information on what tig welding rod to use for what metal. So I will give you some down and dirty advice on what rods you need to handle most anything.

Disclaimer....

I am not an engineer or metallurgist and I dont even play one on TV.

But here is what I do...

get some E70S2 mild steel tig welding rod

E70s2 mild steel tig welding rod - use for welding 4130 chromoly tubing, all mild steel, and even cast steel. (tip....if you have a roll of bare mig wire like e70s3 or e70s6, it will work great in a pinch...just snip some off and straighten...

if its too small, double it up and chuck it up in a cordless drill and twist it tight so you wont have to feed so much wire)

ER308L tig welding rod

ER308L stainless tig rod - when you know that you are welding 300 series stainless steel, (304 is the most common 300 series stainless used), you cant go wrong with er308 rods.

there are others like 316L and if you know what you are welding, its best to use a match.

Hastelloy W tig welding rod ( the W doesnt stand for "wonder rod" but maybe it Should!

Hastelloy W - this is all I need for welding steels that I am not sure of and a whole bunch of other stuff like... stainless steel of unknown grade to carbon steel? use Hast W

Tool steel welded to Stellite? use Hast W.

get the picture?

When you know it is some type of steel, but you are not completely sure exactly what grade of steel...., Hastelloy W covers a multitude of sins.

CYA note: if it is a critical weld, you need to know what kind of steel you are welding

update.....since I originally posted this page hastelloy W has gone way up in price.a really good all purpose rod for welding most stainless to most carbon steel is ER312...its easier to find and a lot cheaper

Aluminum Tig Welding Rods

4043 aluminum tig rod - the most versatile for 3003, 6061, a355 aluminum castings etc.

and do yourself a favor and get some 4047 rod for castings where porosity rares its ugly head.

4047 contains 12% silicon. That makes it flow better, and crack less.

Tig Welding Rods for Disimilar metals and more - ER309

er309 stainless - when mild steel is just too dirty and you need to tig it. 309 stainless will weld hot rolled steel without porosity.

This is not for critical welds that will kill somebody if the weld fails...but it works.

309 stainless is used routinely for making critical welds in the power generation industry. It is designed for welding stainless steel to carbon steel.

Common sense would dictate that if that is the case , the resulting welds would be of a different chemistry on the carbon side of the weld than on the stainless side. Still, they hold up for years even under stress and thermal cycles...

So a bracket on your car should be no problem.

Tig Welding Rods for pot metal

Alladin 3 in 1 for tig welding pot metal jobs. and remember, when you are welding pot metal and things start to flow good, its about to go south.

so when things start to flow...STOP and let cool.

Cast Iron Tig rod

Chronatron makes some pretty good nickel tig rod for welding cast iron.

but I found another rod I have been using with good results.

aluminum bronze - for tig welding cast iron repair jobs on A/C....What??? dont laugh it works great.
